About this work
This patent model demonstrates an invention for a method of making multicolor prints on paper from special compound blocks of pigmented resin; the invention was granted patent number 123266. A series of steam-heated impression rollers alternating with cold rollers melted and then fixed the resin onto the paper. The press bed rested on wedges, so the resin block could be raised as its surface was used up.
