Abstract

Abstract Individual blocks with the register elements provided on one of their sides are fitted to corresponding register pins on a strip-like mounting device and are optionally affixed with small double adhesive tape portions. The mounting device is then fitted to the printing roller, where it engages in bores with corresponding pin-like alignment means. The printing blocks are affixed in conventional manner with double adhesive tape and the mounting device is removed again. In other embodiments, the register elements can also comprise projections on the block and corresponding recesses on the mounting device.
