Title:
THERMAL IMAGE TRANSFER BY SUBLIMATION OR FUSION
Document Type and Number:
WIPO Patent Application WO2004106082
Kind Code:
B1
Abstract:
Method to transfer decorations, from films on which are printed, to whichever decorable objects. This method allows sublimatic and physical transfers. Specular images are printed on films, with sublimable or physically transferable inks, they are then brought in contact with the objects to decorate and transfer heat is supplied. This is obtained creating vacuum between films and objects, by vacuum machines able to seal objects inside films under vacuum. The films are barrier type ( thermoretractable, on the occurrence), able to bear the heat treatment temperatures. The objects of very complex shape, sealed in the films, are dealt in a pressure chamber before executing the transfer. Transfers at low temperature are executed in a decompression chamber. It is possible to print decorations also on intermediate films, positionable on the objects by repositionable adhesives. These, vacuum packaged as said, undergo the decorations transfers treatments.
