Abstract: An embossing block registration system includes a base plate adapted to be mounted in a fixed position within a die chase, an adjustable plate supported on the base plate and adjustable with respect thereto, and an embossing block supported on the adjustable plate and adjustable with respect to the adjustable plate. Securing screws are provided to secure the adjustable plate in an adjusted position relative to the base plate. Fixing screws are provided to fix the embossing block in an adjusted position relative to the adjustable plate. Two adjustment carriages mounted on the base plate are actuated by rotation of associated lead screws and snugly fit within recesses formed in the adjustable plate. Turning each lead screw adjusts the position of the corresponding adjustment carriage to effect movement of the adjustable plate relative to the base plate. The embossing block pivots on the adjustable plate so that a skewing adjustment of the embossing block is also provided.

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.
