<p>The present invention is related to an apparatus for paperless transfer printing, which includes a printer and a heat transfer printing machine, the printer is connected and assembled with the heat transfer printing machine by an endless belt of metal foil, the heat transfer printing machine includes at least a heating transfer printing roller, or a weight bearing crawlet belt, or a weight bearing plate, the heating transfer printing roller can adsorb the belt of metal foil by negative pressure of vacuum or by magnetic means, which result in the close fitting of the belt to the surface of the heating transfer printing roller. The paperless heating transfer printing apparatus also includes a heating device to heat the belt of the metal foil. A set process of printing and dyeing is also proposed in this invention, which used said apparatus. By using this kind of apparatus and the process, the problem, that the metal foil easier wrinkles than paper does is overcomed, and the substrate can close contact with the surface of the roller, the heat can be transferred more uniformly. The patterns the apparatus made are lucidity and less color difference or unsharpness, the pulling force acting on the foil is also reduced.</p> |
