Definitions

  • the present application is concerned with a method for adjusting printing technology and other job-related parameters of a printing press.
  • the visual impression of a Printed images which can also contain text, are affected by many factors. This includes the condition and type of paper used, the type of paper used Colors and dampening solutions and their admixtures, the color density required by the subject, Color distribution, the order of the colors printed on top of each other and the Environmental conditions such as Humidity and air temperature.
  • planographic printing especially that Offset rotary printing also plays a role in the color and water flow Role that strongly influence each other.
  • the influencing factors mentioned are as follows referred to as input values.
  • Some of the listed values are assigned to the material used or can be read from the label and taken into account when setting up a printing press. This includes, for example, the color or paper used.
  • Other predefined input variables are, for example, the color distribution based on the predefined subject, the sequence of the colors printed one above the other, or the preselected printing speed.
  • Such input variables are taken into account in the machine settings of the press (such as, for example, ink zone openings, moisture setting, sheet air blowing, dryer output) at the start of the pressure or production print.
  • Result parameters such as the printed color tone and the color density achieved can be measured with some effort and adjusted on the press.
  • the subjective impression of the operator on the printing press is often more important than the measurement result.
  • One reason for this is that all of the parameters mentioned are subject to certain tolerances, so that the trained eye of the operator is more important for producing an optimal printing result than the results of predetermined machine settings.
  • the known control devices provide some help with the automatic setting of printing machines before printing or during printing however, a large number of characteristic curve fields can only be determined for the printer represent approximate guideline values, which are in the sense of an optimal printing result of Must be changed by hand. This applies to both setting up the press before Start of the production run as well as for the adjustment of the machine during that Printing.
  • the printer is often with settings in the color distribution or faced with faults that differed greatly from the specified characteristics Adjustment of the printing press is necessary, so that in some cases a complex and considerable wastage, which means adjusting the color or moisture, is required. This leads to partly due to the fact that the times for setting up and fine-tuning become a major part of the Machine times can be.
  • a certain remedy can be found through a special achieve a dense network of color presetting characteristics. This requires a lot of effort Characteristic curve determination necessary. Furthermore, almost every case is one of the characteristic curves deviating special case, which must be readjusted by hand.
  • the input values described at the beginning can be divided into the specified values of Input variables and special settings of the machine values by the printer, which the Printer due to his subjective experience must adjust the print result of the Improve printed matter.
  • the input variables are measured objectively or by corresponding description of the materials used for printing (paper, ink) to the printer announced, who then adjusts the machine accordingly.
  • under Input variables through material (e.g. paper, paint), environment (e.g. temperatures, Humidity) and template (for example color distribution) defined objectively measurable Understand variables that influence the setting of the printing press.
  • Under Machine settings are the settings made by the printer on the Understand the printing press that this undertakes to achieve an optimal result, especially the special settings that the printer, as described above, autonomously.
  • the values stored as successfully defined on the basis of the release signal form one Record of a successful setting of the printing press with regard to the underlying input variables describes.
  • the principle of the invention is that Input variables and the machine settings that are successful from the printer's point of view to make available to the control system that these stored data records are available later Print jobs can be used to derive suitable machine settings.
  • the special settings of the machine values by the printer are made by the printer done autonomously because they are either not at all or difficult to measure or because the printer to improve the printing result from the out of characteristic curves proposed or preset machine settings want to or must deviate.
  • the input variables are determined by the parameters of the substrate, the parameters of the subject, determined by the parameters of the environment and certain machine parameters.
  • the parameters for the substrate are, for example, the paper format, the grammage, the Paper thickness or the throw-away behavior of the paper.
  • the parameters of the Subjects are the color distribution, the color assignment or the contrasts or grids.
  • a The input variable for a parameter of the printing press is, for example, the intended one Print speed.
  • the input variables for the parameters of the environment there are for example the temperature and the humidity.
  • the input variables are the printer communicated by descriptions of the materials used for printing and then by this in entered the machine or read it automatically.
  • the special settings of the machine values by the printer concern i. d. R. the moisture (moisture management) and the color distribution (color management) as well as the Air setting for paper transport.
  • the special settings can also Predefined input variables concern the printer itself to improve the Print result of a printed product in the form of a machine setting changes so far that is possible at all.
  • the known efforts to set the settings have already been written above Accelerate or improve printing presses by adjusting the machine settings Store ready for retrieval or by fuzzy logic the control processes be accelerated to readjust the color guide.
  • the object of the present invention is it also shortens the duration of the adjustment processes and the quality of the printed product independent of the experience and qualifications of the machine operator.
  • the present invention is based on the basic idea that certain attitudes are very different have it carried out quickly (if necessary automatically) because it is clearly determined by the input variables are.
  • the special settings to be carried out by a printer take a long time Machine values (machine settings) are comparatively long and often have a lot of waste afflicted. These special settings also require a great deal of expertise and a great deal Experience of specialists who are not always sufficiently available.
  • the invention is therefore based on a method which results from the preamble of the claim 1 resulting genus and solves the problem by the characteristic parts of this Characteristic combination resulting in claim.
  • Material e.g. paper, paint
  • environment e.g. temperatures, air humidity
  • template for Example color distribution
  • machine settings are those of the printer made settings on the printing press understood that this to achieve a optimal results, especially the special settings that the Printer, as described above, autonomously.
  • the values stored as successfully defined on the basis of the release signal form one Record of a successful setting of the printing press with regard to the underlying input variables describes.
  • the principle of the invention is that Input variables and the machine settings that are successful from the printer's point of view the controller so that these stored values at later Print jobs with corresponding input variables can be used. This creates the Prerequisite that with considerable costs from the printer to achieve a good one Print result created values or correction values also for later comparable Printing units are available.
  • the controller searches for an earlier one Combination of input variables that correspond to the current input variables of a new print job are as similar as possible. Because of the previous most similar combination of Input variables are then concluded that the current machine settings have been successful. In order to is created from the stored data records (from input variables and successful Machine settings) to current successful machine settings for new ones Constellations of input variables closed.
  • the requirements for the control are thus when setting up the printing press for a new one Printed matter very diverse. It must be checked which previous combination of Sufficient input variables with the input variables of the new print job to be set up are comparable. It must be checked which tolerances in the event of a deviation from the new one Combination of the previous combination are permissible and for which input values only minor deviations can be tolerated. Based on the results found The new machine settings are then updated by the controller based on the learned Connections in the stored data records changed or the new one Operating personnel made appropriate suggestions.
  • Neural networks are ideally suited to the to meet the task at hand as they are capable of learning. They thus form the growing experience of a printer.
  • the neural network of the printing press is preferably configured in such a way that the processors or nodes working in parallel from the multitude of over time stored data records relationships between certain input variables with recognize successful machine settings.
  • the neural network learns via one Large number of data records, which input variables in which constellation for certain Output variables (machine settings) were of particular importance. It's about that able to weight certain input variables according to their importance.
  • the neural network outputs the most promising machine settings or makes corresponding suggestions depending on the current combination of input variables in comparison with similar previous combinations of input variables.
  • the output values are not necessarily identical to previously set machine settings, as there may well be an unprecedented constellation of input variables.
  • the input parameters to be weighted are, in particular, the paper parameters (such as format, grammage, thickness, stiffness) and color parameters (such as smoothness, emulsion capacity), the dampening solution properties, the environmental parameters (air humidity and air temperature) and subject parameters (such as Color distribution and area coverage).
  • the machine settings such as ink zone setting, humidity setting, blowing air settings etc. are to be selected as output variables.
  • the controller is tolerant of small deviations from certain Input variables is built up. That means the combination of the input variables too can then lead to the output of learned machine settings if the new one Combination of input variables with a previous combination is not identical, but can only be compared to it within certain tolerances.

If a portable code reader is available, the printer has the option of moving to Material and take the reading there, which is then carried out using a suitable Transmission channel is brought to the controller. If the code reader is permanently installed, it can Label with the barcode are brought to the code reader and read there.
  • a another possibility is advantageously that associated with a certain material Code reader in this way on a receptacle for the respective material on the printing press to arrange that when feeding the material or the equipment of the printing press the respective code reader can read the relevant label without further ado.
  • a smart label has the advantage that changes in the material during the printing process can also be taken into account. So can, for example, reduce a stack of paper during a previous one Printing process by a suitable code reader and writer in the smart label be registered.
  • the smart label looks something like a credit card, in which the last one Status of the property of the material is entered. This way you can also easily Changes in the properties of a material from a printing press when changing the Printing machine can be recognized.
