what is the difference between a woodcut and intaglio?

Brief Explanations:

Woodcut is a relief - printing technique where the parts of the block that are not to be printed are cut away, leaving the raised surface to carry the ink. Intaglio is a printing technique where the image is incised into a surface (like metal), and ink is held in the incised lines or areas to be transferred to paper under high pressure.

Answer:

In woodcut, non - printing areas are cut away for a raised printing surface; in intaglio, the image is incised into the surface and ink is held in the incisions.
