Photopolymer plates, usually used for relief and letterpress printing, can be used to make photogravure plates. These polymer plates, when developed, are a hard plastic, which allows for fewer impressions to be made. Some feel that they rival the quality of traditional copper plate photogravure, while others find that the lack of differential ...
The plate's ground side is then dipped into acid, or the acid poured onto it. The acid bites into the surface of the plate where it was exposed. Biting is a printmaking term to describe the acid's etching, or incising, of the image; its duration depends on the acid strength, metal's reactivity, temperature, air pressure and the depth desired.

Pad printing (also called tampography) is a printing process that can transfer a 2-D image onto a 3-D object (e.g., a ceramic pottery).This is accomplished using an indirect offset printing process that involves an image being transferred from the cliché via a silicone pad onto a substrate.
A print made in 1907 from a photoengraved plate. It reproduces a sketch of Parga's castle made by Ludwig Salvator.. Photoengraving is a process that uses a light-sensitive photoresist applied to the surface to be engraved to create a mask that protects some areas during a subsequent operation which etches, dissolves, or otherwise removes some or all of the material from the unshielded areas of ...
The transparency of the glass plate can be used to advantage, in that the plate may be placed over a preliminary drawing on paper to guide the artist in creating a drawing on the plate. This is done by placing the drawing face down on a light table (to allow for the reversal of the image in printing) and placing the vitreograph plate on top of ...
The process of stipple engraving is described in T.H. Fielding's Art of Engraving (1841). To begin with an etching "ground" is laid on the plate, which is a waxy coating that makes the plate resistant to acid. The outline is drawn out in small dots with an etching needle, and the darker areas of the image shaded with a pattern of close dots.
