Abstract
A method of controlling an ink transfer roller is provided. This method achieves stabilized printing quality by evenly distributing ink transfer actions of the ink transfer roller for the number of rotation of a plate cylinder. The ink transfer action of an ink transfer roller is controlled based on the fact whether a value obtained by setting the value of C after calculation as a hysteresis value and adding the number ratio thereto exceeds a predetermined basic value or not, thereby allowing the ink transfer roller to perform ink transfer actions evenly at the number ratio set by an operator. With this method, unevenness in printing quality can be prevented.
