  • Process for printing a substrate by the hot-transfer printing method
    Patent number: 4681034
    Abstract: An article having a substrate with a synthetic resin surface that has an affinity for printing inks is printed with a laser-induced hot print method. A transfer medium, printed on a face side with an image formed of sublimable dyes is faced against the synthetic resin surface, and a laser beam is made to impinge upon the unprinted back of the transfer medium. The laser beam is of sufficient intensity to cause the dyes to sublimate and penetrate at least partially into the synthetic resin surface of the substrate.
