Definitions

  • the invention relates to a device for controlling the printing process in a printing press based on the measurements of a reading device that scans the printing plate clamped on a printing form carrier.
  • measuring methods which measure a plate lying flat on a table or a plate mounted on a cylinder outside of the machine with a large number of measuring heads and the measured area coverage values between memories and in a further operation by means of different data carriers on the setting mechanism of the ink fountain key transfer.
  • a plate cylinder for a rotary offset printing press with a device for zone-wise scanning of the plate color has become known.
  • the coloring in the individual color zones is determined with the help of a densitometric measuring device during the rotation of the plate cylinder over the entire circumference thereof.
  • a system for printing press preparation and control has become known in DE-OS 2 922 964.
  • the default setting mainly affects the inking unit, the dampening system, the dampening and folding unit.
  • the task is to create a system with which the mechanical parts of a printing press mentioned can be automatically preset and further adjusted.
  • devices are to be provided, among other things, with which the necessary mechanical adjustments depending on the data entered are predetermined.
  • presetting parameters such as printing press, print product, printing area and workflow can be entered.
  • the invention is based on the object of storing and retrieving printing process, control and organizational data for monitoring and keeping the printing process constant to achieve from a print-related data medium during standstill and machine run to shorten the dead time of the printing press.
  • the printing plate in its print image-free area not covered by the printing material, namely in the area overrun by the ink and dampening rollers, has at least one information bar containing information data on which information carriers can be fastened during or after production of the printing plate, and that the work bar and the information carrier can be read and stored inside and outside the printing machine by means of reading devices.
  • the work bar with information data is arranged in the area of the ink and dampening rollers rolled over by the plate cylinder, the work bar always remains legible for the reading devices.
  • the printing plate has a work bar with information data in the area free of the printed image and not covered by the printing material.
  • the work bar is arranged in an area on the pressure plate, i.e. the printing plate is a print image memory. Light dust particles that can occur during machine operation are removed in the above-mentioned manner.
  • Data for monitoring the printing process such as: ink control, fountain solution control, maximum number of prints to be carried out with the printing form.
  • a large amount of data for monitoring the printing process is known before the machine starts up and is supplied to the machine by the individual departments, e.g. the IT department supplies organizational data from plate copies, provided plate pre-scanning devices are available using plate scanners, for presetting values of ink fountain keys.
  • the zone for the work bar on sheetfed offset presses is approx. 2-5 mm behind the start of the format.
  • the work bar can also be copied to the end of the print, then the work bar also starts approx. 2-5 mm behind the processing format edge, since the dirt running from the rear edge of the sheet to the print image storage will otherwise contaminate or destroy the work bar.
  • the coding of the work bar is done according to the well-known standard codes. The coding is written in such a way that each command has a unique address and therefore it does not matter from which direction the toolbar is read into the microcomputer.
  • the work bar has an information carrier that can be attached according to the manufacturing process of the printing plate.
  • the information carrier can e.g. be a magnetic card or the area of the printing plate can be magnetized or the information carrier is a punched card.
  • commands or controls even after the printing plate has been produced, can be applied or read onto the latter.
  • the reading unit consisting of a line mark reader, is arranged on an axially traversing common receptacle, parallel to the printing form carrier. A feedback of the axial position of the reading unit to the microcomputer is not necessary since the address of the corresponding command is always read. A precisely positioned (x; y) assignment of the data for presetting and process monitoring is therefore not necessary. In contrast to the previously known drive mechanisms, a simple, inexpensive construction can therefore be selected.
  • the pre-setting of the machine is started.
  • a retrospective check takes place automatically when the print image memory is installed in the machine and read again.
  • an evaluation unit or a process computer is connected downstream of the reading unit, which implements the instructions and commands and forwards them to the operator, to the corresponding servomotors of the machine or to a monitor.
  • no further control device on the machine is required for processing the preset data, e.g. that of the ink zone presetting.
  • the printing press is equipped with an electronic circuit, which allows the data on the work bar to be a) read into the process computer or evaluation unit by hand; the print image memory, i.e. the printing plate, can be located inside or outside the machine, b) when it is stationary Machine to be read by machine and by hand, c) machine to be read in while the machine is running and d) machine to be read in during process printing for process monitoring.
  • the known data carriers can be omitted by applying the work bar to the pressure plate. A previously dead space on the printing plate is used.
  • the printing plate 1 shows a section of the printing plate 1, which is arranged on a plate cylinder, not shown, of a printing press 7.
  • the printing plate 1 has an initial section which is not or is partially overrun by the ink and dampening rollers.
  • an area over which the inking and dampening rollers roll, in which a work bar 2 is located follows up to the start of printing.
  • a dashed line ends the space on the printing plate 1 which has not previously been used for the printing process.
  • the working bar 2 extends across the entire area of the printing plate 1. In the working bar 2 there is an information carrier 6.
  • the information carrier 6 can, for example, have a magnetic area the printing plate 1, which can be read out with a reading head 13, for example a magnetic head.
  • a reading head 13 for example a magnetic head.
  • the work bar 2 there is a Co dation, which can be read by means of a line marker reader 10 or two line marker readers 10, both of which are fastened in a receptacle 12.
  • Another variation can be selected by means of a contrast reader 8 in certain readout situations.
  • Another possibility of reading the work bar 2 can be done via a manually operated reader 9.
  • a further work bar 2.1 can, however, also be arranged in the lateral end regions of the printing plate 1, which can be read out with a fixed line mark reader 10.1 and reading head 13.1.
  • Copying one or more work bars 2 onto the non-printing zones of the printing plate 1 is possible depending on the amount of data.
  • the work bar 2 does not generate a print image on the printed product.
  • the printing plate 1 is thus used in a dead area, the free space previously not used by the printing. There is no risk of confusion between the different print jobs in the print shop.
  • a multifunctional use of the information content of the work bar 2 and the information carrier 6 for controlling organizational processes and machine presettings for printing processes is thus possible.
  • the different data are divided into three groups: organizational data, machine presetting data and data for monitoring the printing process.
  • a direct feedback system during printing can be carried out via the work bar 2 and the line mark reader 10, whereby a direct control or regulation of the printing process is achieved.
  • the printing plate 1, work bar 2 and information carrier 6 together are a print image memory 1.1.
  • Fig. 2 the two ways of reading the work bar 2 and information carrier 6 are shown in a flow chart.
  • the data are read into a central data acquisition by means of the above-mentioned devices 8 and 10 a) outside the printing press, b) inside the printing press.
  • the possibility of reading data during production leads to the printing process monitoring or printing process control processes.
  • the printing process control processes are combined in a central data acquisition composed.
  • the data reading device when the machine is at a standstill mainly concerns information for the printer, such as basic machine settings, work preparations, scheduling and machine allocation.
  • the data that are read outside the machine by the work bar 2 or the information carrier 6 also apply to the individual function groups, such as material procurement, information for the printer, this information being able to be optimally compared with the data reading while the machine is running.
  • the basic settings of the machine, work preparation, scheduling, machine assignment have similar effects. This data can all be compared during the machine run with the data given on the printing plate, so that there is a constant control.
  • the work bar 2 is shown in detail, with its three main data groups: 1) process control data, 2) machine presetting data, 3) organizational data. These data can be called up with the contrast reading device 8, line mark reader 10, 10.1 and reading head 13, 13.1 in the above-mentioned manner during the printing process for an optimal printing control, so that the printers have as little downtime on the printing machines as possible. It is no longer possible to mix up the different print jobs.
