Abstract

A method for imaging a media is provided which includes supporting a substrate and the media in a layered configuration. An imaging head is operated to image the media by directing radiation beams towards a surface of the imaged media while effecting relative movement between the imaging head and the support. A roller is brought into contact with the imaged media. The roller can be brought into contact with an un-imaged region of the surface of the imaged media, the un-imaged region corresponding to a region of the surface of the imaged media that is not impinged by the radiation beams. The un-imaged region could be an edge portion of the media. Relative movement is effected between an axis of rotation of the roller and the support to cause the roller to roll on the regions of the surface of the imaged media impinged by the radiation beams.

Description

200925799 IX. Description of the Invention: [Technical Field of the Invention] This invention relates to a method and apparatus for stripping or otherwise removing media from a substrate. Particular embodiments of this invention are provided in an imaging machine in which a medium imaged into a donor material is imaged to impart a donor material to a substrate and removed from the substrates after imaging. RELATED APPLICATIONS This application claims the benefit of U.S. Provisional Application No. 61/049,423, filed on May 1, 2008, and U.S. Application Serial No. 11/975,418, filed on Jan. 17, 2007. [Prior Art] A color display (such as a liquid crystal display or the like) generally incorporates a color filter for supplying color to a pixel. One technique for fabricating a color filter involves a laser-induced heat transfer procedure. A particular prior art thermal transfer procedure is schematically illustrated in Figure 1A. A substrate ι (often referred to as a "receptor element") is covered with a donor/zero 12 (often referred to as a "body sheet. In the case of a color filter manufacturing, the substrate 10- The system is made of glass and has a generally flat shape. The body member 12 is generally a sheet which is relatively thin and relatively flexible compared to the substrate 1 。. The body member 12 can be, for example, The body member 12 is incorporated into a donor material (not shown). The donor material may comprise a colorant for producing a color filter, a pigment, etc. The body member 12 is exposed one by one for imagewise application. The bulk material is selectively transferred from the donor element 12 to the substrate 1G. Some exposure methods involve controlling the light source to emit a radiation beam. For example, as shown in Figure 1A, one or more can be controlled using 135104.doc 200925799 The laser 14 provides one or more corresponding laser beams 16. In the presently preferred technique, the 'laser beam 16 initiates the transfer of donor material from the imaged regions of the donor element 12 to the corresponding regions of the substrate 1". ^ (Multiple) controllable lasers may contain (multiple) diode lasers, It is relatively easy to modulate, has a relatively low cost and has a relatively small size. This (equal) laser 14 can be controlled to directly expose the donor element 12 image by image. In some embodiments, a reticle is used (not Displaying) exposing the donor element 12 image by image. Once the donor material has been imagewise transferred from the donor element 12 to the substrate, it is generally necessary to remove the imaged donor element 12 from the substrate 1〇. For example, During the manufacture of the color filter, a first donor element 12 can be used to apply a red colorant to the substrate 10, a second donor element 12 can be used to apply a green colorant and a third donor element 12 can be used to apply a blue color. Colorant. After use 'Remove a given imaged donor element 12 from the substrate 1〇, then apply and use a subsequent donor element 12. In various prior art, the donor element 12 is incorporated into one or A plurality of rollers 18 of the plurality of absorbent features 20 are removed from the substrate 10. The rollers 18 are brought into close proximity to the edge 12A of the body member 12 (as indicated by arrow 19) and then the suction feature is applied through the absorbent feature 2〇 such that the donor member is applied 12 edge 12A tight To the adsorption feature 2〇. The roller 18 is then rotated (as indicated by arrow 22) and translated (as indicated by arrow 24) to wind the donor element 12 from the substrate 10 and onto the circumferential surface 18 of the roller 18. The substrate 10 strips the donor element 12. In some cases, some of the donor material corresponding to the exposed regions of the donor element 12 may remain partially adhered to the donor element 12 during the removal procedure rather than pressing Desirably adhering to the substrate 1 (the donor material portion is 135104.doc 200925799 attached to the donor element 12 may make it difficult to remove the donor element 丨 2 from the substrate ι. In some cases, a donor element 12 will be Removal from the substrate 1 造成 can cause an irregular separation between some of the donor material that has been transferred to the substrate 10 and some of the donor material that remains attached to the donor element 12. For example, the figure ... shows a portion of the donor element 12 positioned on top of the substrate 10. A region of the donor element 12 has been exposed to form an imaging region 25. The imaging area 25 is separated from the non-image area 27 by the imaging edge 25A. However, rather than being cleanly separated at the imaging edge 25A during removal of the donor element 12 from the substrate 10, the separation may occur within a larger area within the imaging region 25 that is adjacent the imaging edge 25A. As shown in Fig. 1C, after removal of the donor element 12, the donor material may not be uniformly distributed along one of the regions of the substrate 1 corresponding to the imaging edge 25A. Specifically, the amount of donor material that remains transferred to this region may be less than desired and the distribution of the transferred donor element along this region may be non-uniform. This may result in the formation of an edge 25B that contains cracks and other various discontinuities. These rupture edges may create annoying visual artifacts within the final image. In addition, the donor material can also extend into the non-imaged area 27, which is also undesirable. It is generally desirable to provide methods and apparatus for more efficient removal of an imaging medium from a substrate. It is generally desirable to provide a method and apparatus for more effectively removing a donor element from a substrate after it has been transferred from a donor element to a substrate.

The drag force can be applied using a stop or can be applied by actuating the actuator. The imaging medium is then removed from the substrate. The roller can be stripped of the imaging medium from the substrate after or while rolling on the surface of the imaging medium. In a particular embodiment, the roller can roll in a plurality of different directions on the surface of the imaging medium and the drag force can be rolled over the surface at different times as the roller is in the same direction Different amounts are selectively applied to the roll. The roller can roll on the surface of the imaging medium while maintaining the imaging medium and the substrate in the layered configuration.

"This is for illustrative purposes only and other A suitable image forming device can be used with the present invention to process the media in step 00 to form an image. In this exemplary embodiment, the image is formed by imaging techniques (i.e., also known as exposure techniques). Imaging techniques can use a beam of radiation, such as a laser beam, to form an image on a surface. These images can be formed in a variety of ways. For example, imaging techniques can be used to alter one of the properties or characteristics of an image modifiable layer to form an image thereon.

In other cases, the substrate 110 is stationary and the imaging head 102 is moved. In other cases, both the imaging head 102 and the substrate 110 are moved. In some exemplary embodiments of the invention, imaging head 102 exposes donor body 112 in a one-step and repeating manner. In these particular embodiments, relative movement between the imaging head 102 and the donor element 112 may occur between exposure shots. In some cases, the donor element 丨 12 may be too large to be imaged within a single exposure or scan. Multiple exposures or scans of imaging head 102 may be required to complete an image.

In the illustrated embodiment, the support 101 is used to transport the substrate 11 and the 135104.doc -14.200925799 body 7L member 112 along the path of the aligned main scanning axis 42. In this particular embodiment, the support 丨〇丨 can be moved in a plurality of transport directions (i.e., forward direction 42A and reverse direction 42B). The forward direction 42A is opposite to the reverse direction 42B. The support 1〇1 is reciprocable between the forward direction 42 and the reverse direction 42B. The imaging head 1〇2 is movably supported on the support 105, which rides over the support 1〇1. In this exemplary embodiment, imaging head 1 2 is movable along a path that aligns sub-scan axis 44. In this embodiment, the imaging head 1 2 is movable in the exit direction a and in the return direction 44B. The exit direction 44A is opposite to the return direction 44B. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Here, the imaging head 1 2 can scan the radiation beam 116 bidirectionally on the donor element 12 to form an image. Two-way scanning technology increases imaging productivity because it can be scanned in each of these relative scanning directions. The motion system 109 is provided to cause movement of the support 1〇1 and/or the imaging head 1〇2 and may include appropriate drive, transmission components, and/or guide components. The motion system 109 can include one or more motion systems. Those skilled in the art will recognize that individual motion systems can also be used to operate different systems within the device. A controller ΐ θ8, which may include one or more controllers, is used to control the device 1 〇〇 or a plurality of systems ' including but not limited to the motion system 1 〇 9. Controller 1 〇 8 can cause the image data 104 to be transferred to the imaging head 102 and the imaging head can be controlled to emit a radiation beam 116 based on this information. The controller 1 8 can also control a system other than the device 100, which can be configured to execute appropriate software and can include one or more data processors, as well as appropriate hardware, by way of non-limiting!

Controller 1〇8 may be associated with a material handling system. Figure 2B shows a schematic partial cross-sectional view of an image forming system of apparatus 100. In the illustrated thermal transfer process, the substrate 11 can be secured to the support 1〇1 by various methods known in the art, such as adsorption. In the illustrated embodiment, after the substrate 11 is supported on the support 101, the donor member 112 is positioned in a layered configuration with the substrate 11, wherein the donor member 112 overlies the substrate 11. In order to preserve image quality, it is desirable to prevent the donor element 112 from moving relative to the substrate u during imaging. As shown in Figure 2B, the support 101 includes a bracket 118 that is laterally spaced from the edges of the substrate 11 and has a height substantially similar to the thickness of the substrate U. The support 1〇1 also includes one or more adsorption features 120' that exert a suction force in the space 122 between the support 118 and the substrate 11〇. This suction secures the donor element 112 to the substrate 110. It will be appreciated by those skilled in the art that there are other additional and/or alternative techniques for securing the donor element 112 to the substrate 110 and it should be understood that the present invention accommodates such additional and/or alternative body member fastening techniques. Transfer of the donor material from the donor element 112 to the substrate 1O0 can be accomplished using, for example, various laser induced thermal transfer techniques. Examples of laser-induced thermal transfer procedures used in the present invention include: laser-induced "dye transfer"programs, laser induced "hot melt transfer" procedures, laser induced ablation transfer" Program and Laser Initiation "Quality Transfer" Procedure. In general, the substrate 110, the donor element 112, and the set of donor materials 135104.doc -16 « 200925799 are dependent upon the particular imaging application. In particular embodiments The imaging device 100 is used to fabricate a color filter for the display on the substrate 110. In such embodiments, the substrate 110 is generally made of a transparent material (e.g., glass), the donor element 112. Typically made of plastic and the donor material typically comprises one or more colorants. For example, such colorants may include suitable dye-based or pigment-based compositions. The donor material may also comprise One or more suitable binder materials. In this illustrative embodiment, the 'imaging head 1 〇 2 is constrained to emit a radiation beam 11 6 ' such that it strikes various regions of the imaging element 丨 2 of the imaging region 丨丨 2B Thus, the region U2A of the donor element 112 remains as a non-imaged region and may in some cases provide a boundary around the imaged region U2B. Accordingly, in this illustrative embodiment, the donor material is only from the donor component. 112 is transferred onto the imaging area 11〇B of the substrate 11〇 instead of the non-image area 110A of the substrate 11〇. In the illustrated embodiment, the portion 113 of the non-imaged area 112A is suspended above the substrate 11〇 and The support member 丨丨2 is removed from the substrate u 在 at the end of the imaging procedure. In this exemplary embodiment, it is desirable to have various features on the substrate 丨丨〇 The donor element 112 is removed from the substrate 110 at a manner that reduces the presence of cracks and other discontinuities at the edges. Figure 2C depicts an illustration of one end of the support 101, the substrate 11 and the imaging donor element 112. Partial side view. Removal of the imaging donor element 112 from the substrate 11 is accomplished by a sheet removal device 129, which is illustrated herein as part of the device 1A. specific In the embodiment, the sheet removing device 129 includes a chassis 136 and a plurality of 135104.doc 200925799 rollers (ie, the contact roller 130 and the take-up roller 132). The rollers are coupled by a pair of corresponding rollers (contact roller coupling 138 and The take-up roll coupling 140) is mechanically coupled to the chassis 136. The rolls 130, 132 are preferably substantially cylindrical in shape. The contact roll coupling 138 and the take-up roll coupling 140 permit its individual rolls 130, 132 to rotate about it. The shafts 130A, 132A are rotated. In the illustrated embodiment, the take-up roll coupling 140 includes an actuator 133 that moves the shaft 132A of the take-up roll 132 relative to the chassis 136. Actuator 133 is referred to herein as a take-up roller shaft position actuator 133". The take-up roller shaft position actuator 133 can be controlled by the controller 1A8 using an apostrophe 135. The take-up pivot position actuator 133 may generally comprise any suitable coupled actuator. Non-limiting examples of actuators that may be used to provide a coiled relative position actuator 133 include suitably coupling an electric motor and/or an air actuator. In the illustrated embodiment, the "winding roll face 14" further includes a take-up roll rotary actuator 139 which causes the take-up roll 132 to rotate about its axis 132. The take-up roller shaft position actuator Π 9 can be controlled by the controller 1 〇 8 using the signal 141. [Better, the take-up roller rotary actuator 丨 39 includes a suitable face motor, but the take-up roller rotates The actuator 139 may generally comprise any suitably configured actuator. In the illustrated embodiment, the take-up roll 132 also includes one or more attachment features 134. The adsorption feature 134 may include a hole that is fluidly coupled to a source of suction 143. As is known in the art, the suction source 143 may include a mechanism for establishing a positive or negative pressure differential, such as a properly configured pump or the like. The suction source i43 may be controlled by the controller 108 135104.doc -18- 200925799 using the signal 145. The signal can also be controlled by the source of suction! 43 Apply one or more valves or similar components (not shown) associated with the suction. In the illustrated embodiment, the contact roller 丨3 is a non-driven "idler wheel" In an alternative embodiment, the contact roller 130 may be rotationally driven/special removal device 129 further comprising one or more chassis position actuators 131' which cause between the support ι 1 and the chassis 136 Relative movement. The relative movement between the support 101 and the chassis 136 results in a corresponding movement between the support 1〇1 and the rollers 130 and 132. In the illustrated embodiment, the chassis position actuator 131 causes the chassis 13 6 to move relative to the support 1〇1 to effect relative movement between the support 101 and the chassis 136. In other embodiments, the chassis position actuator 1 31 causes the support i 〇丨 relative to the chassis! 36 is moved to achieve relative movement between the support 1〇1 and the chassis 136. Chassis position actuators 131 may generally include any one or more suitably coupled actuators. Non-limiting examples of actuators that may be used to provide chassis position actuators π 包括 include suitably coupled electric motors and/or pneumatic actuators. When it is desired to remove the imaging donor element 112 from the substrate u, the controller 1〇8 uses a signal to cause the chassis position actuator 13 to establish a relative movement between the chassis 136 and the support ιοί, such that the chassis 136 and the wafer The remainder of the removal device 29 is positioned adjacent one of the edge portions U5A of the donor element 112 (see Figure 2C). In the illustrated embodiment, the sheet removal device 129 approaches the donor element 112 from a vertical direction. In other embodiments, the chassis position actuator 131 causes the sheet removal device 129 to approach the donor element 112 from other directions (or the donor element 112 is adjacent to the sheet removal device 129). In step 310, the sheet removal device 129 is moved toward the donor element 112 until the contact roller 130 is brought into contact with the donor element 112. Preferably, the contact roller π 接触 contacts the donor element 112 within the non-imaged region 112 (i.e., outside of the imaging region 112B). Although not required by the present invention, this positioning of contact between the contact roller 130 and the donor sheet 112 avoids the influence of one of the contact rollers 130 in the imaging region 112B of the donor member 112 and prevents such an effect. Any corresponding degradation of the image within the corresponding imaging region 110B of the substrate 11〇. • In the illustrated embodiment, the take-up roll 132 has not been brought into contact with the donor element 112. In this example, the take-up roll axis position actuator 133 is controlled to cause the take-up roll 132 to not contact the donor element 112. In step 3 20, the contact roller 130 is rolled over the surface of a portion of the imaging donor element 112. In this exemplary embodiment, the contact roller 13 is rolled over a portion of the imaging donor element 112 that includes the imaging region 112B. In the illustrated embodiment of the invention, the contact roller 13 is rolled during the step 300 by the regions of the donor element 112 that have been struck by the radiation beam. In this exemplary embodiment, the contact roller 13 is tumbled along a path extending from the non-imaged area 112A near the edge portion 115A on the imaging area 112B to the non-imaged area near the edge portion 1 Β5Β 112A. Controller 1 使用 8 uses signal 137 to cause chassis position actuator Π 1 • moves chassis 136 (including rollers - 130, 132) in a rolling direction (as indicated by arrow 148 以) to cause contact roller 130 to be in the supported donor element Scroll on 112. In the illustrated embodiment, the contact roller 13 turns (as indicated by arrow 144) as it rolls over the imaging donor element 112. As shown in Fig. 2C, this causes the rotating shaft 130A of the touch roller 130 to move in the direction of the arrow 148A. Figure 2C shows the rolling contact roller 13 在 on the imaging donor element 112 while the imaging donor element 丨丨 2 and the substrate 丨丨〇 remain positioned in the layered configuration of I35104.doc • 20-200925799. The inventors have surprisingly decided that 'rolling on the imaging donor element 1丨2, such as one of the contact rollers 130, can be used to reduce edge discontinuities such as edge discontinuity when subsequently removing the imaging donor element 112 from the substrate 110. The existence of false shadows. Specifically, the inventors have discovered that rolling the imaging donor element 112 prior to removal of the imaging donor element from the substrate 110 can result in reduced fracture of one of the donor materials at the edges of the imaging features, particularly When the donor element 112 is peeled off from the substrate 1丨〇. Although the inventors do not wish to be bound by any particular theory, one possible reason for such improved visual characteristics of the image formation may be due to imaging of the donor element 112 and the substrate 110 as the roller 130 is rolled over the imaging donor element 112. Between existence, micro-sliding " caused. It should be understood, however, that additional or alternative causes may result in improved image characteristics as provided by the present invention. Figure 4 illustrates a schematic force diagram representative of the movement of the contact roller as it rolls over the supported donor element U2. Except for the interface force F, it is shown that all the forces and moments act on the contact roller 13A. These forces acting on the contact roller 130 include a load w imposed on the contact roller 13A. The load w may include a force P imposed by the chassis position actuator 131 on the contact roller 13A to represent the force required to move the contact roller on the surface of the supported donor element 112 in the direction of arrow 148 A and It is illustrated herein that the specific embodiment is provided by a bottom disc position actuator 131. The force Μ represents the frictional resistance or drag force imposed on the contact and is opposite to the direction of rotation of the arrow 144. This drag _ ° is established by various factors, including the frictional resistance of the bearings of the contact roller coupling 138 (not shown in Figure 4). The contact 13G can include a compliant table that can be deflected at the point of contact between the roller 13G and the sensible support member 112 135l04.doc • 21 · 200925799. This variation is shown at region 170 in FIG. These deformations cause the contact between the contact roller 130 and the donor element 112 to occur not in a single contact line but in a specific area that can cause "rolling resistance". Although the deformation shown in Fig. 4 is limited to the contact roller 13A, it should be understood that the deformation may also occur on the surface along which the roller rolls. Figure 4 shows that the resultant force exerted by the supported body member 112 over this region on the contact roller 13 is applied to the reaction force R at point 171. The point 丨7丨 is not directly under the rotating shaft 13 0A, but slightly in front of it. Point 171 is displaced from the center of rotation 172 by a distance b. The distance b is referred to in this technique as the rolling resistance coefficient. It should be noted, however, that b is not a dimensionless coefficient, since it is expressed in units of length.

135I04.doc -22- 200925799 A small amount of sliding sliding may occur in the region of the donor element to the substrate interface near the contact area. The interface force F depends on various factors, which may include a pressing force between the imaging donor element 112 and the substrate 11A (eg, an applied suction between the donor element 112 and the substrate no), the load w and Various friction parameters of the donor element to the substrate interface. Other factors may include such shear forces that must be overcome to shear the donor material at the boundaries of the various image features formed. "When the friction force is large enough to overcome the interface force F," the imaging features are such The donor material at the boundary may be sheared due to frictional forces 6 causing localized shearing of one of the imaging donor elements 112 near the boundaries of the imaging features. Localized shearing of the donor material can in turn reduce the number of ruptures that can occur at the boundaries of the imaging features when the imaging donor element 112 is stripped from the substrate 110. The inventors have discovered that the rolling contact roller 130 across the imaging area i12 significantly promotes reduction in the imaging area n〇B formed in the substrate 11〇 when the imaging donor element 112 is removed from the substrate The artifacts of the edges of the features. The friction force fl can be increased to a desired level in various ways. The relation (3) implies that the friction force fi can be increased by increasing the load W or by using the contact roller 130 having a reduced radius. This can be done in various embodiments of the invention, and various other factors in the other embodiments of the invention may limit the degree of permissible variation associated with the parameters. For example, an increase in excess load W can result in a contact strain that is sufficient to damage the donor material that has been transferred to the substrate, thereby reducing the visual quality of the final image. Reducing the size of the contact roller 13A can result in undesirable deflection in the roller, which can adversely affect the ability of the contact roller 130 to uniformly roll on the donor element 112. Reducing the size of the contact roller 135104.doc -23- 200925799 130 may also contribute to the aforementioned contact strain problem. Increasing the load w also increases the interface force F. In some exemplary embodiments of the present invention, the touch roll 13Q includes a material or geometry that, once the imaged donor element 112 is stripped from the substrate 110, causes a rolling resistance coefficient sufficient to achieve a desired image quality. b. In some exemplary embodiments of the invention, various frictional properties between the contact roller 130 and the donor element 112 are adjusted to achieve a desired image quality. The friction properties can include adjusting the material properties of one or both of the contact roller 130 and the donor element 112 to change, for example, the associated coefficient of friction. The relation (3) also implies that the friction force fr can also be increased by increasing the drag force established by the couple. In the exemplary embodiment of the invention shown in Fig. 2C, the stop-stop 2选择性 selectively adjusts the drag force on the contact stick 13〇 to a desired level suitable for reducing artifacts such as the aforementioned edge discontinuity. The stopper 2 is controlled by the signal 2〇1 Selectively applied as the rolling contact roller 13 turns on the surface of the subject member 112. The required amount drags the force to the contact. The stopper 200 can be controlled by the various signals of the actuator 201. To actuate. It may be particularly advantageous to use the stopper 2, especially in applications where the contact light 13 is performed to perform a variety of different functions. Different from the • other parameters, depending on the specific function requirements The value of the drag force to the contact roller can be easily customized by appropriately activating the stopper 200 in accordance with the required drag force value required for the function. In this regard, a specific one may be required according to the contact report 130. These requirements of the function to selectively activate the stopper 200, Thereby allowing the contact to perform a different function than the 13 。. In the present invention, one of the functions of the stopper 200 135104.doc • 24-200925799 is selectively applied during the step 320 - a sufficient amount The value drags the contact roller 130 to improve the visual quality of the image formed upon subsequent removal of the imaging donor element ι 2 from the substrate 11. In various exemplary embodiments of the invention, the contact roller 130 is controlled along Rolling in a rolling direction that is substantially parallel to a direction along which the donor element 12 is subsequently stripped to remove the donor element 112 from the substrate 。1. In some exemplary embodiments of the invention Debris created by the action of the stopper of the stopper 2 in a particular application (e.g., forming a color filter in a clean room environment) is undesirable. In these embodiments, such debris is minimized. The resulting stopper 200 is preferred. Such a stopper may include, for example, a magnetic powder stopper and a hysteresis stopper. In the illustrated embodiment, the stopper 2 is selectively controlled. To apply rotation Several forces to contact pro 1 0. In other exemplary embodiments of the invention, the drag force may be selectively used in other ways. For example, the contact roller 130 may be a driven roller that is controlled to The drive contact roller 130 rolls on the imaging donor element 2 to move the chassis 丨 36. Various stops can be controlled to selectively apply a force that limits the movement of the chassis 13. 6. Various actuators can be controlled to selectively apply linear drag. To the chassis 136. Suitable parameters for rolling the contact roller 13 on the supported donor element 112 will generally depend on various factors 'which may include the substrate of the donor element 112, the donor material, and the material of the substrate 120. Properties, such as the application of drag parameters, are generally determined by a repeated test procedure. In the illustrated embodiment of the present invention, the contact roller 130 is rolled in a rolling direction (i.e., in the direction of arrow 148 图 in Fig. 2C), which is 135104.doc -25 - 200925799 Π = image formation in ΐ During the 3°° step, the transport _ is along the direction of your movement. This is exemplary and ^/σ is parallel to the main scanning axis 42. In the example of the rolling direction, in the example of the rolling direction, the rolling direction can be substantially flat. During the various exemplary implementations, it is known that the radiation beams are also 丨ω·β 1 universal. In various exemplary embodiments of the invention, the feature pattern may be imaged during the step 300 of the bull. The imaging features within the pattern, ./T/〇 one or more directions are repeated and controllable Φ 接触 contact roller 13 滚动 to roll in a rolling too & farm direction, the rolling direction is substantially Parallel to the one or more directions. In various exemplary embodiments of the present invention, a continuous stripe feature or a pattern of broken stripe features can be imaged during the step fan. The contact roller 130 can be controlled to roll in a rolling direction. The rolling direction is substantially parallel to a direction in which the continuous or interrupted stripe features extend. In some exemplary embodiments of the present invention, the various imaging features formed in step 300 may be formed in a direction that is selected in accordance with a particular direction of scrolling along which the rolling contact roller 13 is subsequently rolled. A particular orientation of one of the imaging features can be selected to facilitate the improvement of visual quality within the final image as the roller is contacted on the donor element 112 and subsequently removed from the substrate m. The imaging donor element 112 is removed from the substrate 11A in step 330. In the particular embodiment illustrated herein, the donor element 112 is removed after the contact roller 130 has rolled across the imaging region 112B to the unimaged region 112A near the edge portion 115B. As shown in Figure 2D, signal 135 causes take-up roller shaft position actuator 133 to move take-up roll 132 to the vicinity of imaging donor element 112. Preferably, the take-up roll 132 is moved closer to the non-imaged area 112A of the donor element 112 at a position 135104.doc • 26·200925799 that is further from the imaging area 112B than the contact roll 130. In the illustrated embodiment, the take-up roll 13 2 is moved to the vicinity of the portion 113 of the non-imaged area 112A. In the presently preferred embodiment, the take-up roller 13 2 is moved to a position near the portion U3 at a position at least partially above the bracket 118. In some embodiments, the take-up roll 132 is moved to a position other than the non-imaged area 112A at a position spaced apart from the edge of the substrate 11 by the fastening feature 120 of the substrate member 112 to the substrate 110. When the 132 is in contact with the donor element 112, the controller 118 uses the signal 145 to cause the suction source 143 to apply suction through the adsorption feature 134. Applying suction through the absorbent feature 134 causes a portion of the non-imaged region 112A (including the edge portion 11 5B) to adhere to the take-up roll 132 (i.e., the absorbent feature 134 secures a portion of the non-imaged region 112A to the take-up roll 132). In some embodiments, the take-up roll 132 contacts the donor element 112 within the non-imaged area 112A and directly applies suction to secure the donor element 丨丨2 to the take-up roll 132. In other embodiments, the take-up roll 132 does not have to contact the donor element 112 prior to applying suction. In such embodiments, when suction is applied through the absorbent feature 134, a portion of the donor member 112 can be secured thereto after being pulled toward the take-up roll 132'. In some embodiments, the controller 108 can close or reduce the suction applied by the absorbent feature 120 before or during application of suction through the absorbent feature 134. In some embodiments, the absorbent feature 134 is located within one or more known locations on the cylindrical surface of the take-up roll 132. In such embodiments, controller 108 preferably uses signal 141 to operate take-up roller rotation actuator 139 in a "position mode". In position mode operation, controller 135104.doc -27 • 200925799 108 uses a control technique that causes the actuator 139 (at its controllable speed range) to move the take-up roll 132 at any speed to achieve a desired position. As illustrated in Figure 2D, the take-up roll 132 The desired position is a position in which the absorbent feature 134 is positioned adjacent the donor element 112. In this illustrative embodiment, the take-up roll 132 is shown to have an absorbent feature in a unique circumferential position on its cylindrical surface. The skilled artisan will appreciate that in other embodiments, the take-up roll 132 may include an absorbent feature at a plurality of circumferential locations on its cylindrical surface. Figure 2A shows that once the edge portion of the donor element 112 is deuterated and secured To the cylindrical surface of the take-up roll 132, the controller 1A uses the signal 135 to cause the take-up roll axis position actuator 133 to move the take-up roll 132 away from the substrate 11 (i.e., in the direction of arrow 146) At least one point One side up) As can be seen by comparing Figures 2D and 2E, the take-up roll axis position actuator 133 causes the take-up roll 132 to be in relative contact with the chassis 136 when the chassis 136 is held in the same position as the contact roll 130. The roller 130 moves. The edge portion 115B of the donor element 112 and possibly some of the non-imaged area 112A are removed from the wrap 101 when the take-up roll 132 is moved in this manner. As shown in Figure 2E, the touch roll 13 Preferably, the crucible is in contact with the body member U2 and can exert a force thereon. Therefore, a portion of the donor member 12 on one side of the contact roller 13 (i.e., the side away from the take-up roller 132) When in contact with the substrate 丨j ,, a portion of the donor member 112 on the opposite side of the contact roller 13 (i.e., the same side as the take-up roller 132) is peeled off from the substrate 110 and bent around the circumferential surface of the contact roller 13A. The characteristics of the contact roller 13 (eg, the diameter and/or material of the cylindrical surface thereof) and/or the manner in which the contact roller 13 is in contact with the donor element 135104.doc • 28-200925799 112 (eg, Class contact force and / or pressure) can be used in The effective contact area between the donor element 12 and the substrate 丨1〇 is controlled immediately prior to stripping. In some embodiments, the effective contact area between the contact roll 13〇 and the donor element 112 is less than the contact roll. 10% of the circumferential surface area of 13. In other embodiments, the ratio is less than 5%. ^ In some embodiments, the force applied between the contact roller 13A and the donor element j12 It is less than the gravitational force acting on the contact roller 130 (i.e., some of the weight of the chassis 136 supporting the contact roller 130). The removal of the take-up roll 132 from the substrate 110 may also involve moving the take-up roll 132 in one or more directions tangential to the substrate 11'. For example, the take-up roller shaft position actuator 133 may cause the take-up roller shaft 132 to move in a curved path. During removal of the take-up roll 132 from the substrate 11A, the controller 1A can use the signal 141 to cause the take-up roll rotary actuator 139 to pivot the take-up roll 132 about its axis 132. Such a tumbling motion of the take-up roll 132 can be used to take up any slack in the portion of the imaged donor element 112 that has been stripped from the substrate 11, or otherwise track the portion of the imaged donor element 112. A required tension. During this period, controller 108 can use signal 141 to control take-up roller rotation actuator 139 in "torque mode" In torque mode operation, controller 1 使用 8 uses a control technique that causes actuator 139 (at its controllable speed range) to move take-up roller 132 at any speed to track a desired torque. It will be appreciated by those skilled in the art that the take-up roll axis position actuator 133 can be moved to move the take-up roll 132 to achieve a desired strip angle of zero. In the illustrated embodiment, wherein the contact roller 13A and the take-up roller 132 are substantially the same size, the stripping angle Θ will be the same as the rotation axis of the rollers 130, 132, 135104.doc -29. 200925799 132A The angle is the same. In some embodiments, the stripping angle θ is less than thirty (30) degrees depending in part on the media (i.e., the donor material, substrate 11 and donor element 112). In the presently preferred embodiment, the stripping angle is less than five (5) degrees. Following, as shown in FIG. 2F, controller 108 uses signal 137 to cause 'chassis position actuator 131 to move chassis 136 in the direction of arrow 148Β (including roll 丨3〇, 132) and use signal 141 to The take-up roll rotation actuator 139 is caused to rotate the take-up roll 132 simultaneously with the support 101 in the direction of the arrow 147. Simultaneous movement of the chassis 136 and rotation of the take-up roll 132 draws the donor element around the contact roll 130 and strips the donor element 112 from the substrate no. The contact roller 130 rotates in the direction of the arrow 146 as it rolls on the imaging donor element 112 in a stripping direction (i.e., in the direction of arrow 148 。). As shown in Fig. 2F, this rotation causes the rotational axis 130 of the contact roller 130 to move in the direction of the arrow 148B. In the particular embodiment illustrated herein, the direction of arrow 148B is in line with the rolling contact roller in step 320! The arrow along the M8A is opposite in direction. In the illustrated embodiment, the braking direction associated with moving the contact roller 130 during step 3 3 与 is opposite to the rolling direction associated with moving the contact roller 130 during step 32. • Preferably, during this portion of the sheet stripping procedure, the controller • 1 〇 8 uses the signal 141 to operate the take-up roll rotary actuator 139 in a "torque mode," 1 〇 8 causes the take-up roll 132 (within its controllable speed range) to rotate at any speed to achieve a desired torque. When the take-up roll rotation actuator 139 is operated in the torque mode to track this required torque, the stripping tension on the donor element 丨 12 is maintained relative to the desired stripping tension. 135I04.doc -30- 200925799 In other embodiments, controller i08 uses signal 丨4丨 to operate take-up roller rotation actuator 139 in a "position mode" to synchronize with the translational position of longitudinal and chassis 136. Position. As the take-up roll 132 rotates in the direction of arrow 147 and translates in the direction of arrow 14, by taking up the roll 132 (ie, wrapping around its cylindrical surface) "roll up" 112. The contact roller 130 remains in contact with the portion of the donor element 112 that is still on the substrate 11A and may exert a force on the donor element i^2. As discussed above, in the illustrated embodiment, the contact roller The contact roller 130 prevents the donor element 112 from separating prematurely from the substrate 11 and ensures that the donor element 112 is separated from the substrate 11 at the desired stripping angle θ. In a particular embodiment, the stopper 2 is controlled to be separated during and after removal of the imaging donor element 112 from the substrate 11 比 during the post-imaging rolling sequence corresponding to step 320 with the contact roller Rolling application on the surface of the imaging donor element 112 Different amounts of drag force are applied to the contact roller 130. That is, a plurality of relative movements between the rotational axis 130 of the contact roller 130 and the imaging donor element 112 and the support 101 are enabled to cause the contact roller to be in the imaging region 112B. Rolling up a plurality of times (i.e., in steps 32A and 33B). During one of the plurality of relative movements, the donor element 112 is removed from the substrate 110 by the stripping method illustrated. In a particular embodiment, the detent 200 is selectively controlled to apply different amounts of drag force to the contact roller 13 在 during each of the relative movements. A different number of selectively applied resistances may include the ratio at step 320 The value of the drag force applied in the drag force value is greater or less. In the illustrated embodiment of the invention, the 135104.doc -31 - 200925799 stop 200 is controlled to apply the ratio during step 33 There is less drag during the step 32. In this particular embodiment, substantially no additional drag to the touch roll 130 is applied by the stopper 200 during removal of the donor element U2 from the substrate 110. Note that even in When actuated, the stopper 200 can still provide some form of minimum drag force. The stopper 2 can be actuated to apply different magnitude drag forces for different durations to the contact roller 130 and the magnitudes And the duration may vary depending on one of the applications involving the contact roller 13A. The stopper 2A may be controlled to selectively apply different amounts of magnitude at various locations along one of the paths along the rolling contact roller 13〇. The drag force is applied to the contact roller 130. The simultaneous rotation and translation of the contact roller 130 and the take-up roller 132 during the sheet stripping process also prevents a "through-print" effect. The blotting effect can occur as the roller is wrapped around a roll to deflect the donor element from the lower substrate (see Figure 1A). Since the media edge can have a non-negligible thickness, the media edge initially secured to the roller can cause a discontinuity in a portion of the unstripped donor element to roll the fastening edge thereon. Since the take-up roller 132 is spaced apart from the substrate 11A, the image applied to the substrate 110 is not affected when the portion of the donor sheet 112 wound on the take-up roll 132 overlaps the edge portion ii5B. The thickness variation caused by the edge portion 115B of the donor element 112 does not affect the image imparted to the substrate 11A. As the contact roller 130 approaches the edge portion U5A of the donor element 112, the controller 108 can use the signal 137 to cause the chassis position actuator ι 31 to move the chassis 136 away from the donor element 112 and can cause the take-up roller to rotate using the signal 141. Actuation 135104.doc -32- 200925799 139 rotates the take-up roll 132 to take up the "tail" of the donor element 112. The controller 108 can operate the take-up roller rotation actuator 139 in a position mode during this partial removal procedure of the donor member 112. Once the donor element 112 has been removed from the substrate 110, a second donor element 112 (eg, a different color one of the donor elements 112) can be positioned on the substrate 11 and can be used similar to the inventors of the present invention. A method to further image the second donor element 112 and remove the second donor element 12 when it has been imaged. In the illustrated embodiment, substrate Π0 is removed from support 1〇1 in step 340. The body element removal device 129 does not have to remove the substrate 11 from the support ι 1 because other mechanisms known in the art can be utilized. In the illustrated embodiment of the present invention, 'the enable in the previous step to cause the contact roller to roll on the imaging area 112B a plurality of times between the rotational axis 130 A contacting the imaging pro 130 and the imaging donor element 112. The substrate 11〇 is not removed from the support 101 during any of the plurality of relative movements. The "pre-scroll" imaging body element 112 can be used to reduce artifacts that may occur when the donor element 112 is removed from the substrate ι 10 prior to removal of the imaging donor element 112 from the substrate 110. Specifically, the transfer to the substrate 11 can be adjusted while the imaging donor element 112 is stripped from the substrate by pre-rolling the contact roller 130 on the imaging donor element prior to removal of the imaging donor element 112. The amount of the donor material on the surface. An artifact such as edge discontinuity can be reduced by this adjustment of the amount of donor material that is transferred to the surface of the substrate. In this regard, the inventors have discovered that the amount and distribution of donor material desired to be transferred to a particular region of the substrate 可j 可 can be varied on the donor member prior to removal of the donor member 112 from the substrate 110. The rolling contact pro 135104.doc • 33- 200925799 130 is reduced, especially when the specific area is near the edge portion of one of the features formed on the substrate ιι. Although the same contact roller 13〇 is used in both the pre-rolling step of the rumor and the stripping step in the specific embodiment, it is known that the person skilled in the art should (4) be more than (four) some (four) each— Different rolling parts are produced. The contact roller 13 can be used only for the pre-rolling dynamic sample of the present invention.
