Abstract
AbstractA polyamide-type of commercial photopolymer was used to form a flexible gravure plate by exposure through a standard half-tone positive. The range of suitable exposures and resulting “etch” depths and cell volumes were determined. Comparisons with a theoretical model of cell volume were made. The plate was used to produce proofs whose densities were plotted against densities of the original. These results show that the variable depth-variable area cell obtained by the use of the 65° shoulder inherent in the polymer produces a final print density comparable with existing gravure systems.
