PRINTING ROLLER FOR CHANNEL-FREE PRINTING

摘要

A printing roller for channel-free printing, in particular for a rotary offset printing machine including a roller core on which a sleeve-shaped printing or transfer form can be positioned. The roller includes a thin intermediate layer provided at least partially between the outer surface of the roller core and the inner surface of the sleeve-shaped printing or transfer form for adjusting the printing or transfer form on the printing roller and for securing the printing or transfer form in an improved manner. The printing roller constructed according to the present invention allows a sleeve-shaped printing or transfer form to be adjusted or fitted precisely and in a stationary manner on the printing roller when slid onto the printing roller without limiting the principle on which the sleeve technique for printing is based.
