PROCESSES FOR THE MANUFACTURE OR REPRODUCTION OF PRINTING SURFACES

Description

B41C covers processes and methods for creating or reproducing surfaces used in printing operations, including techniques for engraving, etching, lithography, and other surface preparation methods. This classification encompasses both traditional and modern processes for manufacturing printing plates, blocks, screens, and similar substrates that transfer ink or pigment onto paper or other materials. The scope includes chemical, mechanical, and photographic processes used to produce the image-bearing surfaces themselves, but excludes the actual printing operation or the resulting printed product, which fall under different classifications.
