Method and device for pre-checking a multicolored printed product to be printed by means of several printing forms with different printing inks

摘要

The invention relates to a method and a device for the preliminary checking of a multicolored printed product to be printed on several printing forms (4) with differently colored printing inks. In order to reduce the amount of manual activities required for the preliminary check and to improve the quality of the preliminary check, it is proposed to produce on at least a part of the printing plates (4) a monochrome proof, which is then scanned with a scanner (8) generate digital image data of the monochrome proof. The image data of the Andrucks are then evaluated in a computer (12), wherein they are preferably compared with digital data for producing the printing forme (4) serving form template to detect deviations between the proof and the printing form template. For further automation, proofs of at least a part of the printing forms (4) and preferably all printing forms (4) of a color set are automatically produced in a press machine (2) using a single proof ink.
