Abstract: The business or other institution is provided with two complementary series of blank form parts. One of these contains one or more elements of a form of construction (multiple ply, window, glassine-patched window, glue spots, patches or strips) which would make it incompatable for use with today's commercially predominate non-impact printers. The other contains none of such elements and is suited for being run through a business computer-controlled non-impact printer for the purpose of printing of variable information thereon, and of being thereafter assembled and united increment for increment with form parts from the first series, using presently available assembling and uniting apparatus, whereupon the united forms may be successively severed into thus individualized communications and dispatched to their respective addresses.
