Abstract
A process for multi-color valley printing and embossing of thermoplastic sheets and the like is provided wherein the number of colors that may be printed on such sheets simultaneously with the embossing operation exceeds the number of different color inks utilized by printing such inks individually in certain area and by blending two or more of the different color inks to print additional colors in other areas. A plurality of such different color inks are applied to the surface of a rotatable embossing and printing roll in a manner such that certain discrete surface areas thereof receive individual layers of a single color ink and other discrete surface areas thereof receive overlapping layers of at least two different color inks. During the embossing operation, the roll is rotated in contact with a sheet of thermoplastic material to emboss a design and print single colors on such sheet in the areas thereof contacted by the surface of the roll containing the individual layers of single color ink, and to emboss and print additional colors derived from blending the overlapping layers of the different color inks under the pressure of the embossing and printing roll in the areas of the sheet contacted by the surface of the roll containing such overlapping layers of different color inks.
