A digital print system for generating and printing selectably shaped shaped optical security devices onto the surface of a substrate, wherein the selected shapes may incorporate a pre-printed pattern. The system includes a digital print engine for generating selectable shapes, a foil assembly that includes a supply of thermal foil optionally carrying a pre-printed optical security pattern, a pressure mechanism for applying pressure between the digital print engine and a surface of the substrate, and an advancing mechanism for co-operatively advancing a substrate, either simultaneously with or independently from the foil, each of which may be operatively controlled by a microprocessor.
