Misprints can be removed from an edition of prints for a number of reasons. Sometimes layers don't line up properly, ink smudges or issues with the paper. Most of the print is still great but it’s not to the standard that artists want to present to their clients - printmakers pride themselves on the quality of their work.

I want to just define some terms here before moving on though..

Misprint - a print containing an error of some sort

Ghost Print - a print that has been deliberately printed using minimal ink to test the layout and qualities of a print block

Artist’s Proof - defined by printed-editions.com as ‘…a term used in printmaking to describe a limited number of prints that are made outside of the regular numbered edition of a print. Artist’s proofs are typically printed before the numbered edition and are used as a way for the artist to make final adjustments to the image or to experiment with different colour combinations.’
