ABSTRACT:
In a method for dry printing of a workpiece (1) or printed article through employing a hot embossing foil (6) and embossing die (15) and by the application of heat, pressure and time, a workpiece (1) and the embossing die (15) are moved towards each other, brought into contact with intermediate clamping of the hot embossing foil (6) thereby transferring heat and moved apart again. The hot embossing foil (6) adheres to the workpiece according to the embossing die (15) and, after a cooling down time, is detached from the workpiece (1) with the exception of the printed image. The surface of the workpiece (1), the hot embossing foil (6) and the thinly-formed embossing die (15) are moved in the same direction with equal or corresponding speed in mutual engagement with surfaces in contact. The contact time and the cooling time for the individual surface regions of the embossing die (15) are controlled through the speed and the angles of contact (9, 10).
