Intaglio (pronounced in-TAL-yo, ) is a family of
printmaking techniques in which the image is incised into a surface, known as the matrix or plate. Normally,
copper or
zinc plates are used as a surface, and the incisions are created by
etching,
engraving,
drypoint,
aquatint or
mezzotint.
Collographs may also be printed as intaglio plates. To print an intaglio plate the surface is covered in thick ink and then rubbed with
tarlatan cloth to remove most of the excess. The final smooth wipe is usually done by hand, sometimes with the aid of newspaper or old public phone book pages, leaving ink only in the incisions. A damp piece of paper is placed on top and the plate and paper are run through a printing press that, through pressure, transfers the ink from the recesses of the plate to the paper.
