This is called thermal printing and was used in older model fax machines and is used in most ...
Relief printing is a family of printing methods where a printing block, plate or matrix, which has had ink applied to its non-recessed surface, is brought into contact with paper. The non-recessed surface will leave ink on the paper, whereas the recessed areas will not. A printing press may not be needed, as the back of the paper can be rubbed ...
Viscosity printing is a multi-color printmaking technique that incorporates principles of relief printing and intaglio printing. It was pioneered by Stanley William Hayter . The process uses the principle of viscosity to print multiple colors of ink from a single plate, rather than relying upon multiple plates for color separation.
