Printing process with on press plate development

摘要

A printing process with a development-on-press type printing plate material involves washing surface of a blanket cylinder of a printing press with a cleaning solution and drying after carrying out printing on the plate material; and then printing on another plate material. The printing is carried by supplying dampening water and printing ink through dampening roller and inking roller of the press, to the printing plate material such that the ink is transferred onto a printing paper sheet through the blanket cylinder when it contacts the plate material mounted on plate cylinder. After printing step, the blanket cylinder is washed and then dried. The plate material is then dismounted from the plate cylinder and another plate material is mounted for printing.
