PURPOSE: To enable the rapid attainment of a prescribed printing density when transfer is made to a regular printing process after a forming process, by a method wherein the thickness of an ink film on a form roller or a plate cylinder is detected by a sensor to control the quantity of ink scraped by an ink scraping device so that the thickness of the ink film be the form reference thickness of the ink film in the forming process and that the thickness of the ink film be the printing reference thickness of the ink film in the regular printing process.
CONSTITUTION: A photoelectric sensor 31 for detecting the thickness of an ink film on a plate cylinder 3 or a form roller 7a just after transfer is made from the form roller 7a is fitted at a prescribed position of the main body of a printer, and an ink film thickness detection signal therefrom is inputted to a microprocessor. A construction is made so that an amount of intrusion of a doctor blade 7b, in other words, the thickness of the ink film on the form roller 7a, is adjusted on the basis of an instruction delivered from the microprocessor.
