Abstract
A method for printing combined jobs having different blanks on a printed sheet includes obtaining area coverage values or inking zone presetting values for printing presses, with which the blanks are printed, from image data of the printed sheet. The area coverage values from an earlier job are compared with those from a subsequent job, in which the number, the configuration or the type of at least one blank differs from the corresponding value from the earlier job. The configuration of the blanks on the sheet is changed if the difference in the area coverages exceeds predefined values. An installation for carrying out the method is also provided.
Claims13
A method for printing combined jobs having different blanks for labels or folding boxes on a printed sheet, the method comprising the following steps:
- obtaining area coverage values or inking zone presetting values for printing presses, with which the blanks for labels or folding boxes are to be printed, from image data of the sheet to be printed;
- before printing, comparing the area coverage values or inking zone presetting values from an earlier print job with those from a subsequent print job, in which a number of blanks, configuration of blanks or type of at least one blank differs from a corresponding value from the earlier print job;
- changing the configuration of the blanks on the sheet, if a difference in the area coverage values or inking zone presetting values exceeds predefined values;
- screening image data of a print job with the changed configuration of the blanks;
- and
- printing sheets containing the blanks.
