Abstract
An apparatus and method for imprinting articles such as tiles by the sublimation transfer of dyes into a dye receptive surface coating provided thereon. A platen having a press member formed of liquid metal and a flexible confining membrane is utilized to heat and press a sheet having the dye imprinted design thereon so as to sublimate such designs into the adjacent coated surface of the articles. The press member is accordingly both capable of transmitting heat and pressure to the surface coating of such articles so as to simultaneously transfer said design and the texture of the membrane, sheet or separate texturing member disposed therebetween to the surface of the article.
