Title:
STENCIL PRINTING APPARATUS
Document Type and Number:
Japanese Patent JP2014162141
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To secure an adequate density image to improve a plate life by controlling a printing pressure even when many sheets are printed in a stencil printing apparatus which operates printing by pressing a printing drum with a prescribed printing pressure of a press roller.SOLUTION: A control part 15 decides a basic printing pressure using the ink temperature detected by an ink temperature-detecting part 18 and first control data of a RAM 16. The basic printing pressure is corrected by the number of printing sheets calculated by a printing sheet number counter 20 and a first printing pressure correction coefficient obtained by second control data of the RAM to obtain a first corrected printing pressure. Further, the first corrected printing pressure is corrected by a difference between an ink temperature and an environmental temperature detected by an environmental temperature detection part 19 and a second printing pressure correction coefficient to obtain a second corrected printing pressure. A printing operation is performed by pressing a printing drum with the conclusive second corrected printing pressure of a press roller.
