Definitions

  • the invention relates to an image processing system for a printing press according to the preamble of claim 1, which is suitable for inspecting static and variable image data.
  • the invention describes a printed product according to the preamble of claim 9, and method according to the preamble of claim 10.
  • Permanent quality monitoring of printed products is state of the art in printing presses today, when an image pickup device in the form of a camera together with image processing is arranged in particular in the last printing unit or at any other suitable location in a printing press.
  • an image pickup device in the form of a camera together with image processing is arranged in particular in the last printing unit or at any other suitable location in a printing press.
  • the transmission of a digital image of a currently printed print image in a memory is possible.
  • There can be made by means of image processing a comparison with an image of a Gut horres. From the comparison information about quality and accuracy of a print are obtained. The information can be linked to operations for further processing of the printed products.
  • Such image processing systems are known inter alia from EP 1 190 855 A1 and EP 0 884 182 B1.
  • the data obtained by the image recording device are compared, for example, pixel by pixel with predetermined setpoint values, whereupon, in the event of deviations from setpoint values, either warnings are output or the printing process is intervened in a corrective manner.
  • DE 203 03 574 U1 describes a device for marking erroneous benefits on a sheet, these sheets later in single use separated and the benefits marked as defective can then be discharged, inter alia, in further processing by suitable devices.
  • variable data to a printed product during printing pass through the printing machine, for example numbering by a numbering machine, a code applied with an inkjet device, an individual cover text, company imprints or an address field.
  • Such variable components would have to be hidden in the previously known image inspection systems in a known manner in the sheet inspection, as they would otherwise produce error messages due to the variability of the print image otherwise.
  • inspecting the variable print image components would be highly desirable because errors in the variable print image, such as the failure of a nozzle of a drop-on-demand ink jet, could be detected immediately. Also, other disturbances, such as marks in the variable print image constituent would be detected immediately.
  • the object of the invention is therefore to allow in a system according to the preamble of claim 1, the error detection of variable data on a printed with static data sheet.
  • the object is achieved by the features of a method according to claim 10, for a printed product having the features of claim 9 and for a device having the features of claim 1.
  • the zones on the print image containing variable data are defined and passed to the image processing system which processes the data captured by the image inspection system. These zones, which contain variable data, are excluded from comparison with a static reference value by the image processing system. Nevertheless, the variable data subframes are captured by the image inspection system and fed to a second image processing algorithm which evaluates the variable data for correct content and / or pressure disturbances.
  • a content check could be carried out, for example, by evaluating the partial image with, for example, an OCR algorithm for font recognition and with a nominal data set, for example from the database or the computer system, which serve to control the variable data printing. For the assessment of the quality of the variable data printing, all techniques can be used, as they are today in the OCR technique or in the evaluation of codes, for example bar codes, today common.
  • a pressure disturbance check can alternatively or in addition to the listed methods, for example, by the fact that the average gray value or the gray value distribution of the partial image with the variable data with an absolute setpoint or setpoints that are between two tolerance limits compared.
  • variable length or variable length variable coding such as a bar code, has a relatively constant gray level distribution that can be described with statistical characteristics. Kicking in the Gray field matrix errors can be recognized as a deviation and the printed variable data field can be recognized as faulty.
  • the invention describes a method in which signatures or benefits are removed in a known manner from the printing process or marked by a suitable marking device when an error is detected in a variable data field by the image processing for analyzing the variable data field.
  • the invention describes a method in which the data processing system which supplies data to the variable printer is acknowledged when a sheet is ejected from the printing process or recognized as defective, so that the sheet with the variable data can be reprinted. Analogously, this also applies to the emphasis individual benefits that were recognized as defective.
  • the missing data record or the record identifier can be stored in any desired data carrier or database. These data can be used for analysis and, if necessary, later reprints.
  • the methods mentioned in the invention are preferably used for printed images whose static content is at least partially printed in the offset printing process and the variable content is printed by known methods such as laser printing, ink jet printing or a numbering during printing run.
