What distinguishes relief printing from other printmaking techniques?

Relief printing is characterized by the unique process of using the raised areas of a printmaking block to create the image. In this technique, the ink is applied to the raised surfaces, while the recessed or lowered areas remain ink-free. This distinctive method allows for a clear and bold impression, as the ink transfers only from the elevated parts of the block onto the paper or other printing surface.

This is what sets relief printing apart from other printmaking techniques such as intaglio, where ink resides in the incised lines rather than on raised surfaces, or lithography, which involves a flat surface where ink is both attracted to and repelled from certain areas. The specific emphasis on the raised elements in relief printing is fundamental to its process and outcome.
