ABSTRACT:
A method and apparatus for effecting sublimation printing of a substrate wherein a matrix comprising the design to be printed is electrostatically charged in a given polarity and then a fine disperse dye powder, oppositely charged, is brought into contact with said matrix wherein the charged matrix attracts the oppositely charged dye particles to effect coating of the matrix with the dye, after which the coated matrix is moved into registry with the substrate to be printed, and specifically in overlying relation with respect to a surface of the substrate that has been coated with a dye receptive coating, after which the matrix is brought into pressurized contact with the coated surface of the substrate to cause sublimation of the dye pattern into said coated substrate surface.
