Abstract

Letterpress plates are inset into selected portions of a longitudinally grooved magnetic cylinder at the imprint station of a paper forms press or collator to facilitate minor modification of indicia during successive print runs. Axially extending grooves 1 at preselected peripheral positions on magnetic cylinder 2 receive letterpress plates 3. Each plate (enlarged in B) has print images 4 etched in conventional manner in a polymer material 5 (e.g., DYCRIL* previously mounted to magnetizable steel backing 6. Plate 3 is held in 1 by magnetic attraction between 2,6. Where matter to be printed is less than a full sheet wide, 2 is shorter than shaft 7 so it may be positioned therealong according to desired location of such matter.

Quick Change Imprinting

Letterpress plates are inset into selected portions of a longitudinally grooved magnetic cylinder at the imprint station of a paper forms press or collator to facilitate minor modification of indicia during successive print runs. Axially extending grooves 1 at preselected peripheral positions on magnetic cylinder 2 receive letterpress plates 3. Each plate (enlarged in B) has print images 4 etched in conventional manner in a polymer material 5 (e.g., DYCRIL* previously mounted to magnetizable steel backing 6. Plate 3 is held in 1 by magnetic attraction between 2,6. Where matter to be printed is less than a full sheet wide, 2 is shorter than shaft 7 so it may be positioned therealong according to desired location of such matter. Circumference of 2 equals that of the plate cylinder, not shown, that prints the nonvariable matter on the major portion of the form upstream of the imprint station. To print four forms 5-1/2 inches long, four identical plates 3 are set in respective grooves 1 spaced 5-1/2 inches apart on a 22-inch circumference. These four identical small plates may be imaged as one large plate with three registration lines along which the large plate is then cut to form the small plates.

Thus, where a chain store orders forms that are identical for each store except for specific identifying indicia (e.g., store number and address), the identical indicia is printed by a conventional plate cylinder and readily changeable plates 3 pri...
