Collagraphy is a printmaking technique developed by numerous artists in the 50's, 60's and 70's which involved creating 3 dimensional plates and printing them using intaglio (ink held in the depressions on the plate) and relief (ink applied to the surface of the plate) methods. Glen Alps who was one of my MFA professors at the UW is considered one of the innovators of collagraphy and I believe came up with the name. Though anything glued on a plate could be printed, Alps liked us to work with the paper based Upsom Board, cutting into it and glueing paper, string, or ground walnut shells on it. Before printing the plates were sealed with laquer.
