Method and apparatus for adjusting temperature of printing press

摘要

A method and apparatus are provided for adjusting the temperature of a printing press, which can effectively adjust the temperature of plate cylinders (12) and rollers (12-22) in each inking arrangement in a press for multicolor printing on cylindrical bodies (C) and make it possible to conduct the printing, without the appearance of scumming even in waterless offset printing presses. A first system conduit (25) for adjusting the temperature of rollers with an ink feed function in each inking arrangement and a second system conduit (26) for adjusting the temperature of rollers with an ink distribution function are provided, the temperature can be adjusted separately in the first system conduit and second system conduit, and plate cylinders (2) are cooled by blowing cooling air (61) whose temperature is set to a prescribed temperature from an axially extending portion of the plate cylinders in the axial direction of the plate cylinders. <IMAGE>
