Abstract

The method for concurrently forming and hot-transfer printing a semimanufactured product which is of a thermoplastic synthetic resin or comprises a thermoplastic synthetic resin as a surface coating to be printed, which method comprises bringing said product, maintained at forming temperature, into contact under pressure with a sheetlike dye carrier suitable for transfer printing, said dye carrier being present on a heatable backing mold heated to a temperature suitable to effect dye transfer printing and having thereon a coherent layer of a moistened water absorbent material which supports said dye carrier, said backing mold being present in a forming mold in which said product is formed under pressure concurrently with said transfer printing.
