Abstract
In a double-sided color printing press, first and second color bars of a print are scanned to acquire alignment information of control patches, so that the first and second color bars are recognized whether they are printed on the first or second side of the print based on the alignment information. The alignment information of the patches acquired is compared with alignment information previously stored in a memory means so that when they are matched, information on the print quality of the patches evaluated is transmitted to the printing press in the order in which they are scanned in scanning directions, and when they are not matched, the information is transmitted to the printing press in the reversed scanning order. The amount of ink is thus controlled based on the information on the print quality in the order in which they are transmitted.
