ABSTRACT:
A business forms assembly and method of forming is provided wherein a continuous web defines a plurality of successive form sets and wherein the web is divided longitudinally by a slit indicator line to define adjacent form parts for each set. Carbonless transfer technology is employed, such that a back side or undersurface of one form part (the upper part) is coated with carbonless microcapsules, while a front side or upper surface of the adjacent form part (the lower part) is coated with a co-reactant resin coating. The arrangement permits variable information to be printed on the adjacent form parts as the web passes through a non-impact printer. Thereafter, the web is longitudinally slit, separating the adjacent form parts which are thereafter interstacked so that the coating on the undersurface of the upper form part lies in full surface engagement with the coating on the upper surface of the lower form part. The respective form parts may then be adhesively secured. Thereafter, information imaged onto the upper form part is simultaneously imaged onto the lower form part.
