Abstract
For the permanent printing of a substrate with fixed and/or variable data, a hot blocking-foil having a heated pigment surface, together with the substrate to be printed, is led through a stamping station in which pigment indicia are serially transferred by action of a print head towards a pressure-receiving surface, between which the heated pigmented foil and substrate are passed.
Claims24
A method of hot-stamp variable printing of a substrate, which method comprises:
- (a) providing a substrate to be printed, and a blocking-foil providing on one surface thereof facing the substrate, a layer of pigment which is transferrable under applied contact pressure when heated;
- (b) preheating the layer of pigment to its transfer temperature a temperature below its melting point sufficient for transfer of pigment to the substrate under subsequent applied contact pressure;
- (c) passing the substrate and blocking-foil having the preheated pigment surface, between a variable stamping indicia printer and a pressure-reaction member for receiving a printing force forming a stamping zone;
- and
- (d) serially transferring pigment as indicia from the blocking-foil to the substrate by contact pressure induced by pressing the blocking-foil having a heated transferrable-pigment surface against the substrate by action of a stamping force applied by movement of the indicia printer toward and against the blocking-foil and substrate.

A method of hot-stamp variable printing of a substrate, which apparatus comprises:
- (a) providing a substrate to be printed and a blocking-foil providing on one surface thereof a layer of pigment which is transferrable under applied contact pressure when heated;
- (b) preheating the layer of pigment to its transfer temperature a temperature below its melting point sufficient for transfer of pigment to the substrate under subsequent contact pressure;
- (c) feeding the substrate and blocking-foil having the preheated pigment surface between a variable stamp indicia printer having a printer head and a pressure-reaction member for receiving a printing force forming a stamping zone;
- and
- (d) serially transferring pigment indicia from the blocking-foil to the substrate by contact pressure induced by pressing the blocking-foil having a heated pigment surface against the substrate by action of the stamping force formed by movement of the printer head toward the pressure-reaction member and against the blocking-foil and substrate, said indicia being applied by movement of the printer head transverse to the direction of feed of the substrate and blocking-foil to the stamping station and while feed through the stamping station is interrupted.
