Abstract

A printing roller for channel-free printing, in particular for a rotary offset printing machine including a roller core 1 on which a sleeve-shaped printing or transfer form 2 can be positioned. The roller includes a thin intermediate layer 7 provided at least partially between the outer surface of the roller core 1 and the inner surface of the sleeve-shaped printing or transfer form 2 for adjusting the printing or transfer form 2 on the printing roller 1, 3, 4, 6 and for securing the printing or transfer form 2 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.
