Synonyms for "collotype printing" include plate printing, photolithography, and photomechanical printing. Plate printing involves the use of a flat printing plate to transfer ink onto paper, similar to collotype printing. Photolithography, on the other hand, uses photosensitive materials to create printing plates and achieve high levels of detail. Photomechanical printing involves a similar process, but also utilizes different types of equipment and techniques, including photoengraving, photogravure, and heliogravure. These methods are typically used for reproducing photographic images and are popular in the printing and publishing industries. However, they have largely been replaced by more modern printing technologies.
