ABSTRACT:
A system for producing decorative plates for photoprinting includes forming variously colored translucent wax layers into a laminar bar from which transverse thin sections are cut and mosaicked edge-to-edge on a transparent support, back-lighted and photographed to produce a positive transparency; both pre-sectioning and post sectioning distortions are employed and a matching "open face" disposition pattern provides symmetry.
