A proof obtained by offsetting a wet proof or print onto a clean, slightly wet sheet of paper.
A counterproof is made by running the print, before the ink has dried, through the press against another sheet. The resulting image is in reverse of the print, but in the same direction as the plate. Artists often make counterproofs during the printmaking process to facilitate corrections. See offset.
An impression taken from a freshly printed, still damp sheet onto another paper. This produces an image identical to the image and perspective of the printing plate. With the confusion of the mirror image thus eliminated, the artist has an immediate and unbiased opportunity for assessment and final changes.
