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.
