ABSTRACT:
An intaglio printing plate is prepared by coating a copperplate-engraved plate having a superficial chromium layer with an ink-accepting material such as a hardenable epoxy or acrylic resin, an enamel varnish, or a chemically or electrolytically deposited metal, and removing said layer from the non-grooved parts by treatment in a ball-graining machine. The ink-accepting material remaining in the grooves forms concave recesses suitable for wet offset printing with the precision, complexity and fineness of a copperplate design.
