ABSTRACT:
A matrix for plastic letterpress printing plates and the method of formation thereof are presented wherein the matrix material prior to molding is thicker than the desired molded matrix. The "non-printing" areas of the matrix are compressed to at least seventy percent of the density of the compressed "printing areas" in forming the matrix, and the matrix may then be ground to desired thickness to obtain desired heat transfer characteristics.
