Claims11
A multicellular compressible article comprising
- (a) a volume of compressible foam cut ot predetermined dimensions,
- (b) a design imprint on the surface of the foam desposited by direct heat transfer sublimation of sublistatic ink.
A method of making an imprinted multicellular article comprising the steps of
- (a) applying a transfer paper, carrying an inverse printed design in sublistatic ink on one surface, said one surface side down on the surface of compressible cellular foam material,
- (b) applying heat to the other surface of the transfer paper to cause transfer of the ink in the design to the surface of the foam directly under the transfer paper, without applying compression force on the foam.
