Definitions

  • the invention relates to a method and a device for automatically controlling the register between impressions (printed images) in a multicolor rotary printing press according to claim 1 or claim 10.
  • the register deviations can be measured, for example, by means of a register controller and automatically regulated to the predetermined desired position. For this purpose, at least one marking of each printing unit is printed, whose respective position is measured to the mark printed by another printing unit. From a deviation from a desired position, a correction signal is generated, which is then carried out by suitable devices (such as register rollers).
  • suitable devices such as register rollers.
  • a register controller operates in such a way that the markings for measuring the register positions are printed in a relatively small acquisition window in the circumferential direction.
  • the print images of the printing units to be measured must be prepositioned to a few mm during the setup of a print job, so that the printed on a web markers in the detection window next to each other or come to rest.
  • a web path length (web path) between the printing units must be brought to a certain size, for example an integer multiple of the print format (cylinder circumference). This can be achieved, for example, by adjusting the web path length between 2 printing units by rolling in the web path, which are adjusted, for example, by register spindles, or by adjusting the relative angular positions of the cylinder carrying the printing plate happen.
  • the resulting roll positions or angular positions in turn depend, for example, on the web guide, the printing format and the stretching of the printing material.
  • the procedure is such that the entire printing system is brought into the register for new jobs by manually giving control commands to rollers in the web path or to the positioning means of the forme cylinder.
  • the result is checked by means of a web monitoring system.
  • the achieved actual positions are then taken over as set positions and stored and subsequently kept constant there, for example in a control process.
  • This process is very lengthy and depends on the skill of the operator, which inevitably but always has a large consumption of substrate result.
  • a quite conceivable solution is that due to unique presumed positions for each print size (cylinder circumference), a presetting of the forme cylinder or web travel rolls is effected by means of register spindles (hereinafter also referred to as spindle positions).
  • the EP 0 070 565 describes a method in which the brand printed by him in each printing unit is driven in each case under the sensor immediately following the printing unit. Investigations carried out within the scope of the invention have shown that this method is very time-consuming and, despite some improvements, still consumes a considerable amount of material and is not very precise due to mechanical engagement. It also depends on the skill of the printer, the brands of the individual printing units suitably place.
  • a clear improvement offers the EP 1 132 203 B1 with the approach to make such a pre-positioning automatically.
  • the basic idea is that by skillfully switching on and off of pressure in an iterative process, an automatic determination of any actual positions of marks and their correction can take place.
  • printing is first started in the last unit and the position of the mark printed there is detected by the sensor behind this printing unit and the position signal of a fixed rotary encoder in which the mark has been detected is finally registered for this position Position around a measurement window formed.
  • This operation is initially in the machine from the beginning back to the second Performed printing unit, so that now for each printing unit a measuring window is formed uniquely around the printed by the respective previous printing brand.
  • a disadvantage of this method is that a double pass each with a pressure in each printing unit is required.
  • the described method can only be used if only the register mark per printing unit lies in the scanning path of the web scanner. If other objects or marks are also printed within the scanning track, which is often the case, one code mark per printing unit must be additionally printed at a known distance from the mark for recognition.
  • the disadvantage of this is that the ID tag occupies an extra space, which increases the measurement window and thus reduces the usable area for the subject.
  • a rotary printing machine RD which has in the web running direction L of a web 10 successively arranged printing units D1, D2, D3 and D N. This means that, depending on the number of colors to be printed, corresponding numbers of printing units are present, with the printing unit D N symbolizing the last printing unit in the web running direction L in each case.
  • Each of the printing units has an associated printing cylinder 1, 2, 3 or N1 and an associated impression 4, 5, 6 N2.
  • a control and regulating unit 7, 8, 9 and N3 is provided for the impression roller position and the pressure.
  • each printing unit D1 to D N is associated with a drive controller 11, 12, 13 or N4 for the printing cylinders 1, 2, 3 or N1.
  • Encoder 14, 15, 16 and N5 for the angular position of the respective printing cylinder 1, 2, 3 and N1 are assigned to each printing unit D1 to D N.
  • a measuring system or a scanner 17, 18, 19 or N6 is also provided, which serves to detect the position of one or more register marks, the pressure units D1 , D2, D3 and D N are printed on the web 10 together with the impression or the printed image.
  • control unit 30 is provided for the impression rollers 4 to N2, which is signal-connected to the respective control and regulation units 7, 8, 9 and N3.
  • the control unit 30 is further coupled to a sequence control unit 33, which in turn is signal-connected or coupled to a control unit 31 for angle-synchronous positioning of the pressure cylinders 1, 2, 3 or N1.
  • This control unit 31 is in turn connected to the drive controllers 11, 12, 13 and N4.
  • the measuring systems 17 to N6 are, as is apparent Fig. 1 results, further connected to a computing unit 32 for calculating the angular position of the printing cylinder 1, 2, 3 and N1 in relation to the printed image.
  • the computing unit 32 is coupled to the sequencer 33.
  • Fig. 2 In the embodiment according to Fig. 2 are all elements according to those of the embodiment Fig. 1 correspond with the same reference numerals.
  • the Fig. 2 however, represents a rotary printing press RD R , with register spindles 36, 37 and N8 is provided.
  • the register in the web direction L In contrast to the rotary printing machine according to Fig. 1 is the register in the web direction L not on the relative angular position of the printing cylinder 1 to N1, but via the web path between the printing units D1 to D N by means of each one of the associated register spindles 36, 37 and 38 set, each in the web running direction L behind the printing units D1 to D3 are arranged.
  • Fig. 2 illustrated embodiment of the invention further comprises drive units 34, 35 and N7, which serve to position the associated register spindles 36, 37 and N8.
  • These drive units 34, 35 and N7 are connected to a control unit 38 for the register spindles, which is coupled to the sequencer 33, as shown in detail in the illustration of Fig. 2 results.
  • a sequential control - each printing unit D1 to D N following its preceding in the "mark-and-mark" mode - can be switched over to a control according to a stand color.
  • this operation is generally not required to achieve registering.
  • a method is referred to, in which the register error for each printing unit D1 to D N with respect to a predetermined printing unit that prints the so-called. Stand color, measured and adjusted accordingly. Conveniently, this is the first printing unit D1.
  • a sensor is the construction as a spectral multi-range probe (for example, RGB), which can be used in addition to the color code. This is very helpful insofar as it can be assumed that when known colors are used, spectral identifiers are also present, which can then be used in the second level to confirm the detected objects.
  • a spectral multi-range probe for example, RGB
  • Such an identifier may consist, for example, of data from a color database or a color parameter information transmitted from the prepress.
  • the coding and decoding described above is much easier if, as a register measuring head, it is advantageous to use a camera which determines the brand form in a simple manner according to conventional digital image processing methods of recognition. If a color camera is used, by means of the at least three color channels present there, the selective color information obtained there can additionally or also be used alone in the manner described above.
