Definitions

  • the invention relates to the following methods or objects:
  • a rotary printing press in which the relative positions of rollers involved in the printing process can be optimized due to the monitoring of the printed image.
  • the aim of the scan is usually the acquisition of measured values to desired sizes of the printed image. Often the longitudinal or transverse registration of the printed image is in the foreground. More recently, measured values with regard to the completeness of the printed image (also the thickness and uniformity of the color transfer, see, for example, US Pat. EP 1 249 346 B1 ) and errors in the printed image, or on the parallelism of the run of the printing substrate, etc. obtained by such scans. Often, these measured values are then also used to control the corresponding characteristic of the print in online mode and or to set the print parameters at the beginning of production.
  • the DE 10 2004 044 341 A1 such a lighting system.
  • the field of application of the illumination system is the feeder of a sheet-fed offset printing press.
  • the lighting system includes a bar that provides substantially homogeneous light that falls on the sheets whose run is to be controlled. From these arcs, the light is reflected back to a sensor.
  • the EP 0 983 853 A1 proposes a method in which the sensor system side facing away from a transparent substrate is illuminated with homogeneous light.
  • the DE 103 52 174 A1 suggests something similar.
  • An additional illumination of the side facing the sensor system is also of the former EP 0 983 853 A1 known.
  • more effective illumination of the print image is a continuing need.
  • the JP 03808937 B2 therefore suggests the use of a plurality of lamps that produce both direct and diffused light.
  • none of the above observation methods is suitable, in a method for optimizing the relative positions of the rollers involved in the printing process, as z. B. of the EP 1 249 346 B1 is shown to be used. This is especially true when printing transparent or opaque substrate. For these reasons, the quality of the entire roll position adjustment process is still scalable.
  • the object of the present invention is to provide an improved method for optimizing the printed image generated by a printing press by adjusting the relative positions of the rollers involved in the printing process, which achieves better results even with exotic substrates.
  • the object is solved by the features of claims 1, 6 and / or 11.
  • homogeneous radiation is characterized by a relatively uniform intensity of radiation.
  • the scanning range of a sensor system is just the area - here the printing material - which is scanned by the sensor system.
  • the sensor system will be attached to the path of the printing material web through the printing press and scan parts of the printed images passing it. In general, the sensor system will be mounted on the side of the printing material on which the pressure is applied.
  • An illumination element is any device which aligns the electromagnetic radiation suitable for illumination with the scanning region. This means that a lighting element takes over the final alignment of the radiation on the substrate.
  • a lighting element may first be a light source that emits light "directly” to the scanning area or a mirror device that redirects the light there. Also mixtures between both systems or other alternatives - like glass panes - are possible.
  • homogeneous light The properties of homogeneous light include, as mentioned, a uniform intensity of the same over a certain area (probably the sampling range here).
  • a uniform intensity of the same over a certain area probably the sampling range here.
  • diffused light As a diffused light is generally understood a light that illuminates the "scene" contrast and shadow. Diffused light is created by flat light sources. In the production of artificial diffused light find light formers such as umbrellas, soft boxes or reflections on uneven, matte, reflective objects use. In nature, diffused light comes about when the sky is overcast. As an alternative, parallel light has crystallized out. Parallel light can be generated for example by Paraboloid- or Ellipsoldspiegel. When light sources are at the focal point of these mirrors, parallel light is produced analogously to the traditional headlamps of cars. As alternatives, light-emitting diode arrays or even laser diode arrays are advantageous.
  • This second electromagnetic radiation falls from the same side of the substrate on which the sensor system is located. This measure requires the presence of any lighting element on this side of the printing material. A rather random lighting by stray light is not meant.
  • the presence of direct, that is to say non-diffuse, radiation has proven to be advantageous.
  • the use of light or Laser diodes or planar arrays of these components has achieved advantageous effects in experiments.
  • the lighting element or elements emanating from the second electromagnetic radiation should advantageously be positioned relative to the scanning region on the printing substrate and the first lighting element such that the second radiation falls past the latter lighting element. By passing it is meant that the second radiation propagating rectilinearly does not fall on the first lighting element. This should also be the case when considering the proper refraction of light at the interfaces of the printing substrate. However, if scattering effects - such as dirt or material damage - cause small amounts of light to strike the first lighting element, this is irrelevant to the above definition. From the measured values obtained by the sensor device, control commands for optimizing the printed image can be derived. As a rule, the measured values are to be forwarded to a computing device for this purpose. This can be part of a system which comprises at least the sensor device and with which the printing press is equipped. However, the computing device can also be integrated as a hardware or software component in the machine control of the printing press.
  • this document proposes recording the course of the intensity of the light reflected by the printing material as a function of the relative roller positions. In the present case, of course, the transmitted from the substrate and possibly reflected light should be recorded, which is very advantageous in connection with the teaching presented above.
  • a target image contains one or more light intensity target values for a surface section.
  • Optimized relative positions of the rollers involved in the printing process can also be found by first measuring measured values relative to a relative position via a radiation intensity measurement and then changing the relative position by a fixed value, for example.
  • the optimization of the relative positions of the rollers involved in the printing process is according to EP1249346 B1 from suitable actuators, which are controlled by control commands of the control or computing device made.
  • the optimization of the roll positions according to these teachings can be done before (starting) or during the printing operation. This is also the case with registering.
  • a line scan camera is advantageous.
  • Systems with which printing presses can be retrofitted or retrofitted for the purpose of monitoring the printed image are advantageous. They include a sensor system, at least one lighting element and a certain intelligence, which provides in the form of software and / or hardware components for the evaluation of the measurement signals. If no hardware components are contained in the system, then the machine control takes over its tasks.
  • Fig. 1 shows a printing machine in the region of the scanning 1.
  • the scanning region 1 with first electromagnetic radiation 2 - preferably light - the radiation source 3 is applied.
  • This radiation passes through the transparent surface 4, the radiation 2 becoming diffused.
  • this diffuse radiation 2 is incident on the scanning region 1.
  • This 1 is scanned by the sensor system 5.
  • These two light sources together with the mirrors 6a and 7a, in whose focal points are the light sources, the lighting elements 6b and 7b. Each of these two lighting elements directs radiation 8 onto the scanning region 1.
  • the second radiation 8 is direct radiation.
  • the second electromagnetic radiation 8 does not fall on the translucent surface 4, which here forms the first illumination element 3 in the sense of this document.
  • the printing material or the printing material web 9 are conveyed in the direction of the arrow z via the guide rollers 10, 11.
  • the elements of FIG. 2 are largely identical to those of FIG. 1 , However, the first lighting element is formed by the mirror 13. This reflects diffusely, so that the first electromagnetic radiation 2 is again diffuse. This mirror 13 also transmits the first radiation 2 to the scanning region 1 as the last mechanical optically active element. As a rule (but not always), the printing ink will be located on the side of the sensor element 5 of the printing substrate 9.
  • FIG. 3 shows again the same arrangement as FIG.
  • a diaphragm 15 is located between the diffuse surface 4 and the substrate 9, wherein between the diffuse surface 4 and the substrate 9, a diaphragm 15 is located.
  • a diaphragm may form a shadow on the diffuse surface 4, the due to the second electromagnetic radiation 8 can be avoided.
  • Such shadowing can be achieved by the interaction of the second electromagnetic radiation 8 with patterns in or on the printing material web 9.
  • Such shadows can falsify the measurements of the sensor system 5.
  • Another way to avoid the shadowing is to choose the distance A between the surface 4 or another optically active first element behind the printing substrate so that the second electromagnetic radiation falls past this element 4.
  • this distance and the selection of the angle of incidence of the second electromagnetic radiation 8 on the printing material 9 can be matched to one another such that a second electromagnetic radiation 8 impinges on the first element 4 stored on the printing material from the point of view of the sensor system.
  • This is at a minimum distance B (see FIG. 3 ), which arises from the above-mentioned geometrical considerations, the case.
  • the extension of the element must also be considered
  • a further possibility of avoiding the shadowing consists in a coordination of the light intensity I emitted by the first radiation source 3 and the photosensitivity of the sensor system 5.
  • FIG. 4 again shows essentially the features of FIG. 2 , wherein a lens 16 is additionally present.
  • This lens assumes a bundling of the first electromagnetic radiation 2, so that first electromagnetic radiation 2 of sufficient intensity arrives at the printing substrate.
  • This measure can be very advantageous because the diffusion of the radiation often causes them to diverge.
  • the lens other light beam means could be used.
  • the mirror 13 could be pronounced as ellipsoid and / or paraboloid mirror. Incidentally, all measures relating to the provision of diffuse or parallel or to the bundling of first electromagnetic radiation 2 are made, also advantageous for second electromagnetic radiation 8 applicable and vice versa.
  • the Figures 5 and 6 take up another topic, the processing of which is advantageous in connection with the present invention. It is advantageous if, in the scanning region in the web running direction z and / or in the direction of the working or printing width x, the intensity of the first and second electromagnetic radiation has the same (local) intensity profile. This is symbolized by the same curves of the graphs 20 and 21, which represent the course of the light intensity on the illuminated part of the printing material web 9 in x and / or in the z direction. Similar light sources 3, 6 and 7 can do this. Also a same or similar color temperature (in FIG. 6 spectral intensity profile) is advantageous. For clarity, in FIG. 6 the wavelength ⁇ plotted against the spectral light intensity I.
  • Graphs 22 and 23 are intended to show that this pattern is the same for the first 2 and second electromagnetic radiation 8 (although the intensity here has other amounts).
