Title:
REFERENCE MARK DETECTION METHOD FOR PLANOGRAPHIC PRINTING PLATE, PROCESSING METHOD FOR PLANOGRAPHIC PRINTING PLATE, AND A PRINTING METHOD
Document Type and Number:
WIPO Patent Application WO/2015/122513
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a reference mark detection method with high reference mark detectability, a processing method with high punch position accuracy, and a printing method with high printing accuracy. This reference mark detection method for a planographic printing plate is characterized by involving a step a, in which an exposed planographic printing plate with a reference mark is prepared, a step b, an irradiation step in which an irradiation light source irradiates around the reference mark position of the planographic printing plate, and a step c, an imaging step in which an imaging device images the reference mark; a polarizing plate and a 1/4 wavelength phase difference plate are arranged between the irradiation light source and the planographic printing plate, and between the imaging device and the planographic printing plate.
