Relief printing

The basic concept of relief printing. A is the block or matrix; B is the paper; the thick black lines are the inked areas. (The thickness of the ink is greatly exaggerated for illustration.)

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 or pressed by hand with a simple tool such as a brayer or roller. In contrast, in intaglio printing, the recessed areas are printed.

Relief printing is one of the traditional families of printmaking techniques, along with the intaglio and planographic families, though modern developments have created others.
