line plate
Quick Summary
Photoengraving is a technique used to create printing plates through photographic methods. A plate coated with a light-sensitive material is exposed to an image. Depending on whether it's for relief (letterpress) or intaglio (gravure) printing, the plate is then processed.
Line plates are a type of photoengraving where all image areas are either black or white, meaning no halftone screen is needed. Suitable for line drawings and etchings, the negative from a process camera is directly transferred to the metal plate. The non-printing areas are etched deep enough to prevent ink from transferring to the paper during printing.12
