Abstract

An ink transfer pressure between cylinders in a flexographic printing system is controlled to provide consistent image quality. A flexographic printing plate is provided that includes an image region arranged to print an image pattern having printed image features and a pressure characterization region outside the image region arranged to a print pressure characterization pattern. Ink is transferred from an anilox cylinder to the flexographic printing plate with a first transfer pressure, and from the flexographic printing plate to a recording medium with a second transfer pressure. An optical property of at the printed pressure characterization pattern is measured and used to adjust one or both of the first and second transfer pressures.
