ABSTRACT:
A method of producing an indicia transferring surface including affixing an inert material in the shape of indicia to a base sheet containing a curing inhibitor coating. A curable compound is placed on the surface of the base sheet in contact with the indicia shaped inert material and is allowed to cure. After a curing period, the curable compound is separated from the base sheet. The curable compound includes a cured portion and an uncured portion. The uncured portion is removed, leaving raised areas of the cured compound that were in contact with the indicia shaped inert material. The raised areas may then be used to transfer the impression of the indicia to another surface.
