Definitions

the present invention relates to a device in a printing process-processing Machine with a register sensor for register measurement between at least two printed on one another printed color separations of a Print image, wherein the register sensor, the deviation between two superimposed lying color separations on the substrate optically detected and to a computer and register marks for acquisition with this register sensor.
Every printing press with multiple printing units generally has the risk that the color separations printed on one another are not printed exactly one above the other and have so-called register deviations. That's why every printing press offers at least two printing units the possibility of these register deviations by To minimize correction devices.
the changed registry settings can doing by hand by an operator of the printing press in the control of the same be entered or it is an automatic control device, an automatic Register adjustment, built-in, which by means of a sensor register deviations recognizes and transmits these to the control of the printing press, allowing the controller the press makes appropriate changes to the settings to the Minimize register deviation.
Such a device is known from DE 101 32 266 A1 known.
register sensors and thereby to be detected To provide register marks, which provides a reliable optical detection of the Allow register deviation of all inks involved relative to each other.
the new two-quadrant photodiode features an array of two photosensitive Elements on which by optics a field to be illuminated, which on the Printing material is present, is displayed. Such a field is one on the Substrate applied register mark.
the photosensitive elements change the image of the illuminated field into electrical signals around, which in a downstream electronics such.
B. a control computer of the printing press or a separate measuring electronics are converted into a measured variable, which is a measure for the size of the register deviation.
a control computer of the printing press or a separate measuring electronics are converted into a measured variable, which is a measure for the size of the register deviation.
a measure for the size of the register deviation Depending on how many measurement fields on each other relatively arranged color separations are present on the substrate are several Measurement runs needed.
the largely rectangular evaluation of the Two-quadrant photodiode obliquely with respect to edges of the conveyed substrate are aligned.
edges of the register marks on the substrate usually do not run parallel to the edges of the substrate, but formed as inclined wedges are, with a diagonal arranged photodiode the detection of these oblique edges be improved.
the register sensor a Four-quadrant photodiode is whose measuring surfaces at least partially oblique edges exhibit. With such a four-quadrant photodiode it is in contrast to parallel or diagonally oriented two-quadrant photodiode possible, both oblique and to recognize straight edges optimally.
the photodiode has four measuring fields, which once vertically and once diagonally divided. With a corresponding interconnection The evaluation electronics can thus provide optimal detection of both parallel and oblique aligned register marks can be achieved.
the register sensor is a CCD imager whose Signals evaluated by means of image processing electronics and the computer be supplied.
imaging elements are used here, which deliver the signals to an image processing electronics.
the CCD image converter thus work as a video camera, which the parallel or obliquely oriented edges of the Registered register mark, wherein the captured by the camera image in the image processing Electronics is processed by means of appropriate algorithms so that the location of the parallel and oblique edges of the register marks the calculator of the substrates processing machine can be transmitted. Even so, is a reliable one Detection of register marks possible.
a register mark for recognition by a register sensor which several wedge-shaped in the circumferential direction of the printing material Contains color areas, where one color is the reference color used as a reference and the others are the register colors to be controlled.
a register control is basically choose a reference color to which the other colors can be regulated in register.
this reference color is black (black) that all other colors are fixed on black.
the register mark is a field for length calibration contains, as well as a field, which consists of a wedge of the selected as a reference Reference color exists, and another field, which is the register color to be controlled contains.
a register mark is usually referred to as a coarse register mark, wherein the Measuring electronics, the width of the field for length calibration is known and so the Register sensor can be easily adjusted when scanning the field for length calibration can.
the register mark on the measured Substrate has a defined number of parallel lines. The parallel lines are used as a kind of bar code to increase the information content of the register marks enlarge. Based on the lines z. For example, check if it is actually a Position field is or is not yet another field of view. It is thus verifiable whether the Measuring electronics evaluates the correct measuring field.
the parallel lines have different widths are executed.
the different widely executed lines various built according to today known type barcode used to in the Register mark to encode different information.
the type of Code the mark so that the capturing sensors of the printing material processing Machine can identify the brands before their actual evaluation.
a measuring field for detection by a register sensor so build up that the measuring field is point - symmetrical and the color of a Color separation as solid shows.
To check the correct register setting are suitable point-symmetric forms outstanding. It is relatively difficult to get out of it To calculate adjustment recommendations, but symmetry errors can be relative easily detected by register sensors, so that these brands excellently are suitable for checking the correct setting of the register.
the measuring of the color can be done by a photodiode or a CCD image converter by measuring the full-tone field in the color separation done.

Printing units 4, 5 wherein the last in the sheet transport direction printing unit 5 with a Inline measuring device is equipped.
every number of printing units 4, 5 conceivable, wherein the inline measuring device is not necessary in the last Printing unit 5 must be installed.
the inline measuring device 6 serves primarily for Spectral measurement of the print control strip on the signatures 705 after the Go through the printing press 1 to make an automatic color control can.
the inline measuring device 6 which is the shape of a measuring beam has two register sensors 15 mounted, these register sensors 15th in principle also be integrated into the measuring beam 6.
the register sensors 15 are attached in the edge areas, so that they respectively the longitudinal in sheet running direction lateral edge region of the arc 705 capture. If in the printing press no Inline measuring device 6 is present, then the register sensors 15 by means of a separate suspension in the printing unit 5 over the transport path of the print sheet 705th appropriate.
the register sensors 15 are so close to the sheet transport path that they are the registration marks on the printed sheet 705 easily can recognize and on the other hand are not arranged too close, so that the printed sheets 705 the register sensors 15 do not touch and thereby dirty or damage.
FIG. 1 are on the inline measuring device 6, which is the shape of a measuring beam has two register sensors 15 mounted, these register sensors 15th in principle also be integrated into the measuring beam 6.
the register sensors 15 are attached in the edge areas, so that they respectively the longitudinal in sheet running direction lateral edge region of the arc 7
the sensors 15 on the measuring beam 6 are the Inline measuring device mounted and removable together with this, which is again installed in the vicinity of the printing nip 100 of the last printing unit 5.
This offers the advantage that the printed sheet 705 is measured by the inline measuring bar 6 or the register sensors 15 always from the printing nip 100, which from a Pressure cylinder 8 and an impression cylinder 7 is formed, and of the Sheet grippers 101 of the impression cylinder 7 is held and thus for measurement is stabilized.
the printing units 4, 5 of the printing press 1 each have side walls 14 on, in which the printing cylinders 7, 8 are mounted. In addition, each of the printing units assigns 4, 5 an inking unit 13.
a computer 10th To control the entire printing press 1 is a computer 10th present, which transmits to a setting commands to the printing press 1 and on the other hand monitors the printing machine 1 by continuously measuring values from the Inline measuring device 6 and the register sensors 15 to the computer 10 transmitted become.
the register sensors 15 are in the control of the Pressing machine 1 involved, so that occurring during the printing process Register deviations between individual color separations on the printed sheet 705 through the computer 10 can be adjusted.
FIG. 2a A first embodiment of the register sensors 15 can be seen in FIG Two-quadrant photodiode is constructed. Normally, two register sensors are 15 in attached to the lateral areas of the printing unit 5, so that they are the edge regions of You can scan sheet 705 with the register marks. The two quadrants of the Photodiode of the register sensor 15 are rectangular in shape and parallel to the Front edge of the funded by the printing press 1 sheet 705 aligned. The two surfaces of the register sensor 15 are connected so that the difference of Signals to the computer 10 is supplied. By means of the embodiment according to FIG. 2a, it is possible to the output signal of the sensor 15 for detecting oblique edges improve.
the photodiode is oblique to the front edge of the print sheet 705 aligned to better recognize the oblique edges of register marks. Even if this then horizontal edges of the register marks recognized worse be, so leads the oblique arrangement of FIG. 2a but to a more uniform Signal, which improves the detection of the position of the register marks overall.
FIG. 3 Another embodiment according to FIG. 3 combines the advantages in recognition straight and oblique edges of register marks with each other.
the Register sensor 15 a four-quadrant photodiode, which is a straight and an oblique Subdivision have.
the tapered register sensor surfaces 16 it is possible outstanding edges to recognize, whereby by the straight subdivision also straight edges can be detected very well.

the signals 16.1 and 16.2 and the signals 16.3 and 16.4. For the detection of straight edges, however, the signals 16.1 and 16.2 and the signals 16.3 and 16.4.
the summing operations resulting two signals are then subtracted.
the computer 10 therefore has four Inputs for the four fields of the four-quadrant photodiode of the register sensor 15.
electronics for evaluating the register sensor 15 can also be outside the Calculator 10 may be housed directly in the sensor 15 or the measuring bar 6, in which case the electronics still has two outputs for straight and oblique edges, their signals be passed to the computer 10.
FIG. 4 shows a register mark for fine register adjustment.
the Feinregistermarke 17 has wedge-shaped markings for four colors and allows so register-correcting the printed images applied in the printing units 4, 5 the print sheet 705.
One of the wedge-shaped color marks expediently the topmost mark in sheet transport direction, is in reference color printed, which is mostly black.
the other three wedge-shaped color markings represent the three colors to be adjusted to the black color Feinregistermarke 17 can be detected by the register sensor 15 by means of a measurement, so that when measuring over a print sheet 705 a complete register measurement all colors is made to each other. This can be at any occurrence of Register deviations by means of the computer 10 immediately in the settings of Pressing machine 1 are intervened to the next printed sheet 705th To bring about changes.
a so-called coarse register mark 18 is shown, which only shows two wedge-shaped markings for two colors.
the upper wedge-shaped Marking Reference color to which the color of the lower wedge-shaped marking points is regulated in case of deviations.
the reference color also located above the reference color one bar-shaped marking for length calibration, which has a fixed width of z. B. 4 mm.
the register sensor 15 readjusted, or checked, if this is a different length than that in the computer 10th stored 4 mm signaled.
the coarse register mark allows in contrast to Fine register mark 17 only the regulation of a color on a reference color, so that a complete set of register metrics only across multiple sheets 705 across is to transmit.
FIG. 6 shows the image of a location-coded identification tag, the components of which are all in FIG the reference color are printed.
the dog tag contains two wedge-shaped ones Markings and a certain number of lines.
the lines can be different be executed wide, the wedges are used to determine the lateral and circumferential position.
the lines are used to check whether it is actually a location field.
the location-coded identification mark 19 is therefore on the sheet in the sheet transport direction Seen ahead of the register marks and thus signals in good time to the register sensor 15 that at a predetermined programmed distance a register mark 17, 18th follows.
the lines of different width but also others can be Encrypt information in a barcode and read from the register sensor 15.
FIG. 8 A further embodiment of a register mark can be seen in Fig. 8, in which a conventional register mark with a reference color of a color to be controlled with a additional full-tone field of the reference color is provided as a combination mark 21. Also with that is it is possible by means of a mark both register deviations between reference color and To measure color to be measured, as well as the full tone of the reference color in the large to measure rectangular section.
a register mark for two colors 22 is shown, with both for the reference color as well as for the color to be corrected solid tone fields are present, so not only for the reference color but also for the color to be adjusted next to the register deviation in each case a color measurement can be made. It is clear to the person skilled in the art that all listed register marks 17, 18, 19, 20, 21, 22 basically arbitrary with each other the print sheet 705, in particular in the edge region in the circumferential direction and Side direction, can be present.
the fine register marks 17 serve primarily to the printing process of To correct the pressure phase, since there are only small deviations and thus All colors on each sheet 705 can be monitored. As soon as possible Deviations in the fine register marks 17 can be seen, the Grobregistermarken 18 are measured again by means of the register sensors 15 to the To explicitly measure the offset between the individual colors, so that the adjusting motors the register in the individual printing units 4, 5 from the computer 10 according to the Can compensate for deviations.
