Definitions

  • the relative position of the partial images must be can be adjusted to each other in order to obtain a pressure suitable for the register.
  • register setting devices with which the position of one of the partial images in the printing direction and across the printing direction Moving and twisting can be changed. It is known to be in contrast Specify rich color as the reference color and the location of all other drawing files used inks relative to the reference color.
  • the status of the partial images are used for crosses that are viewed visually with a cross-mark reader be or register marks, their reflection values with a photoelectric sensor be included.
  • the relative position of the Drawing files are kept independent of each other. Another option is there in determining a reference position regardless of one of the partial colors, all Drawing files can be set in relation to the reference position. In this case applies none of the part colors as reference color.
  • the actuating amounts are the register setting devices relatively large.
  • the control and Control devices for register setting speed-optimized.
  • the position of a partial color moves according to the timing behavior of the control and actuators Reference to its target position, with a certain overshoot around the target position can do what disappears after a period of time.
  • a reference color can serve as the leading color, the change in position of which other partial colors somewhat delayed due to the effect of a control device consequences.
  • the object of the invention is to provide a method for register control To develop overprint of several partial colors, which is the number of Reduced cleaning processes and which improves print quality.
  • the ongoing change in the position of the drawing files results in a cleaning effect for the pressure transmission material, especially for rubber blankets from Offset printing machines.
  • the change in position means that other areas of the Print transfer material are used in the ink transfer. Contamination is caused by the print transfer material during ink transfer peeled off and transferred to the substrate with the printing ink.
  • Register setting elements are the position of all part colors in the printing direction and across to do this, e.g. B. amounts between 0.01 and 0.03 mm in a cycle of approx. 2-6 minutes, changed. The amounts of the adjustment are significantly larger than the grid width of the Pixels.
  • the cycle duration can be based on the period mechanical natural vibrations of the printing press can be matched.
  • the amplitude, the stroke and the curve of the cyclical changes in position can be based on the grid width and grid angle of the drawing files are coordinated. It is the same possible the movements of the drawing files with regard to the mechanical To optimize the construction of an elastic cylinder lift.
  • the movements can vary according to the distance and direction of textile fibers of the elevator and / or align according to the pattern of a structured elevator surface.
  • the Speed profile of the motion sequences can change in the printing direction and across distinguish clearly. For example, the changes in position of a partial image in Print direction is faster than across the print direction.
  • the last printing unit of a printing press for printing is highly schematized in FIG represented on a web 1.
  • a printing cylinder 4 When conveying the web 1 in the pressure gap 2 between one Transfer cylinder 3 and a printing cylinder 4 is corresponding to a field Printing ink placed on web 1.
  • the drawing file is a color separation on a printing form 5 generated, which is located on a forme cylinder 6, which is in rolling contact with a blanket 7 of the transfer cylinder 3 is.
  • the partial image includes an actual usable print image 8 as well Register marks 9.
  • the position of the partial image on the web 1 is in the printing direction x and in Page direction y set so that the drawing is exactly the same as the previously printed one Drawing files.
  • Register setting devices 10, 11 are provided. When the register setting device 10 is actuated, the forme cylinder 6 and the printing form 5 are displaced in the lateral direction y. There is an equal displacement of the partial image on the web 1 in the lateral direction y. When the register setting device 11 is actuated, the phase position of the forme cylinder 6 and the printing form 5 is set in relation to the phase position of the transfer cylinder 3. There is a shift of the partial image in the printing direction x.
  • the register setting devices 10, 11 are connected to a control and regulating device 12.
  • the web 1 is scanned with a photoelectric detector 13 along a line 14 which extends in the pressure direction x and d r the register marks 9, 15, 16 of all the color separations are printed. With the help of the detector 13, the positions of all partial images on the web 1 can be detected.
  • the detector 13 ran the actual value signals for the register deviations r u , r s in the circumferential and lateral directions to the control and regulating device 12.
  • the control and regulating device 12 contains a setpoint generator 17, a comparator 18 and a control element 19 for each of the printing inks.
  • the actual value signals r u , r s are compared in the comparator 18 with setpoint signals w u , w s of the setpoint generator 17 compared.
  • Control variables 19 s s , s u are formed in the control element from the comparison signals and are supplied to the register setting devices 10, 11.
  • the setpoint signals w u , w s for a base color are subject to ongoing long-period changes, the actual value signals r u , r s of the base color and the other partial images rapidly following these changes.
  • the position of the partial image of the base color on the web 1 thus changes in accordance with the vector diagrams shown in FIGS. 3-6.
  • the numbers entered in FIGS. 3-6 describe the sequence of the displacements in the xy direction.
  • the displacements are in the range of 0.01-0.03 mm, whereby a cycle is completed in a period of 2-6 minutes.
  • the displacement ensures that always other areas of the rubber blanket 7 are ink-carrying, whereby dirt accumulated on the rubber blanket 7 is transported away via the color and the material of the web 1.
  • the register of the standard color and the other colors carries out one rectangular movement.
  • Fig. 4 or 5 there is the possibility to provide two or four rectangular motion cycles by one common position 20.
  • the variant shown in FIG. 6 is concerned a back and forth displacement starting from a starting point 20.
  • the displacements in the printing direction x and in the lateral direction y can be different run fast.
  • the displacements can run along curved paths. It it is possible to change the shifting sequences for different subjects to be printed to design differently. For subjects that tend to form moires or for Printing machines whose mechanical vibrations lead to cyclical register deviations can lead to the displacement processes with regard to phase, frequency and amplitude be dimensioned according to these phenomena.
  • In the tax and Control device 12 can be provided with several selectable displacement processes become.
