Abstract
A matrix board and the method of manufacture thereof are presented wherein the board has a relatively thin carrier sheet, a relatively thick layer of syntactic foam on the carrier sheet and a relatively thin layer of phenolic resin and filler over the relatively thick syntactic foam layer. The matrix board is capable of being molded at low pressures on the order of fifty psi, thus making it particularly suitable for use with rubber and photopolymer pattern or master plates and also making it particularly suitable for formation of deep relief matrix boards.
Claims10
A matrix board for molding printing plates including:
- a carrier sheet;
- and
- a layer of syntactic foam on said carrier sheet, said layer of syntactic foam including, by weight, from 25-50% thermosetting resin, said thermosetting resin being not more than partially cured, from 25-75% hollow particles and from 5-25% an aqueous latex dispersion binder;
- said matrix board being deformable under pressure of from 25 psi to 125 psi and curable on exposure to heat to form a matrix board for the molding of printing plates.
