#CMT# #/CMT# The method involves choosing a reference point in a print image, and measuring a position of the reference point in the print image. Deviation between the measured position and a corresponding predetermined expected position is determined, and the position of the print image is corrected based on the deviation. Another position of the reference point is measured in the print image, and deviation between the measured position and another corresponding predetermined expected position is determined. The position of the print image set against an edge of a paper (1) is corrected. #CMT# : #/CMT# An independent claim is also included for a device for checking quality of a print image on a substrate during a printing process by a printing press. #CMT#USE : #/CMT# Method for checking quality of a print image on a substrate during a printing process by a printing press. #CMT#ADVANTAGE : #/CMT# The method corrects abnormalities in the print image and efficiently checks the quality of the print image, thus reducing the amount of proofs or other material needed for setting the printing press. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a paper path. 1 : Paper 3, 3', 4, 4' : Margin sections 7 : Cutting line 9 : Folding line. |
