Which of the following techniques is NOT part of the intaglio family?

Intaglio is a printmaking technique where the image is incised into a surface, and the ink collects in the grooves created. The techniques that are a part of the intaglio family include etching, engraving, and others that involve this incised method of image creation.

Relief printing, however, operates on a different principle. In relief printing, the parts of the printing plate that are raised above the surface are inked, while the incised or lower areas do not take ink and remain unprinted. This fundamental difference in the process distinguishes relief from intaglio techniques.

Therefore, relief is not associated with intaglio and is properly identified as the correct answer in this question, reinforcing the crucial distinction between these printmaking methodologies.
