Control unit and method for a printing press

摘要

A controller or print control unit (20) comprises an image analyzing part (26) automatically analyzing an image for printed matter and an inference part (21) adjusting the value of a control parameter related to a printing machine (30) with fuzzy inference. The inference part (21) acquires the feature of the image such as "solid", "halftone" or "light" with the result of analysis by the image analyzing part (26), and decides each control parameter in response to the feature of the image. The printing machine(30) makes printing output with the adjusted control parameter transmitted from the controller (20). The feature of the image may alternatively be supplied as an instruction from an operator through a feature specifying part (29). Thus, a print control unit (20) capable of excellently and simply adjusting the control parameter for the printing machine (30) in response to the feature of the printed image is provided.
