GRAPHIC ARTS PROCESS SIMULATOR MODIFIED FOR LETTERPRESS SIMULATION

摘要

Disclosed is an improved graphic arts process simulator, which enables accurate simulation of a letterpress graphic arts process. Existing graphic arts process simulators generally include an analog signal processor in which various signal processing elements are used to process an electrical signal representative of a halftone transparency in accordance with the steps of a selected graphic arts process. The improvement described herein is a modified analog signal processor which simulates nonuniformities that normally occur in a letterpress graphic arts process and more specifically simulates the dot etch loss which normally occurs when a printing plate for letterpress printing is made from such a halftone transparency.
