ABSTRACT:
A print-through form comprises a top and a base layer with the top layer having a pattern of openings in at least one region, the pattern of openings having center-to-center distances substantially less than the size of characters or other elements to be printed. Ink applied to the region or regions with openings forms characters on the top layer by marking the area between the openings, and on the base layer in the same operation through the openings, marking the area on the base layer exposed by the openings through the first layer. More than two copies in a single printing pass may be accomplished with forms of more than two layers, wherein the patterns of openings expose area on all the intermediate layers and the base layer. In various embodiments forms may comprise sheets affixed by peelable adhesive, by folding larger sheets, and by edge gluing with removable strips made by perforation lines. Some forms are made to be fed through traction feeders from continuous webs.
