Abstract
A printing press includes an ink roller group, image exposing section, pre-inking controller, and CPU. The ink roller group supplies ink stored in an ink fountain to a printing plate mounted on a plate cylinder. The image exposing section exposes an image on a printing plate before plate making which is mounted on the plate cylinder. The pre-inking controller forms an ink film thickness distribution corresponding to the image to be exposed on the printing plate on the ink roller group. The CPU performs image exposing and ink film thickness distribution formation concurrently at least partly by controlling the image exposing section and the pre-inking controller. A control method for a printing press is also disclosed.

A printing press comprising:
- an ink roller group for supplying ink stored in an ink fountain to a printing plate mounted on a plate cylinder;
- image exposing means for exposing an image on a printing plate before plate making which is mounted on the plate cylinder;
- ink film thickness distribution formation means for forming an ink film thickness distribution corresponding to the image to be exposed on the printing plate on said ink roller group;
- and
- control means for performing image exposing and ink film thickness distribution formation concurrently at least partly by controlling said image exposing means and said ink film thickness distribution formation means.
A control method for a printing press including an ink roller group for supplying ink stored in an ink fountain to a printing plate mounted on a plate cylinder, comprising the steps of:
- exposing an image on a printing plate before plate making which is mounted on the plate cylinder;
- forming an ink film thickness distribution corresponding to the image to be exposed on the printing plate on the ink roller group;
- and
- controlling to perform image exposing and ink film thickness distribution formation concurrently at least partly.
