Print product e.g. paper sheet, production method for use in e.g. paper sheet processing rotary printing press, involves retreating printing substrate after printing and drying, and polishing immediately after drying

摘要

The method involves printing a printing substrate (111) e.g. paper sheet, with a print ink. The printing substrate is dried under utilization of an infrared radiation e.g. near-infrared (NIR) laser radiation, with high power densities. A print color is dried under utilization of the infrared radiation. The printing substrate is retreated after printing and drying. The printing substrate is polished immediately after drying. An independent claim is also included for a print material processing machine for lithographic offset printing.
