Printing machine

Abstract

Abstract PURPOSE:Not to consume printing paper uselessly, by a method wherein a printer is, in a switching manner, driven everytime when the number of plural print products reaches respective print product manufacturing datum in the printer where print products of plural classes are successively continuously obtained. CONSTITUTION:The continuous printing paper 5 from a feed part 1 is successively alternately printed with the first and second printing apparatus 21A and 21B of print part 2 and produced as print products of plural clases via a process part 3. Hereupon, the quantity of good print products therein is counted by the pulse for counting print products and by the output from the print product quantity detection means 75 composed of the detectors of print quality and process quality 76 and 77. When said quantity reaches above-mentioned datum, switching signals are successively generated and the first and second print apparatus 21A and 21B are successively alternately driven by those switching signals. Thus, printing paper is not uselessly consumed and futher the reprint due to shortness can be prevented.
