ABSTRACT:
A printing machine (10) is adapted for printing a plurality of imprints (12) onto a sheet (14) divided into a plurality of sequentially longitudinally spaced printing fields (16) having a selected field length and being divided into a plurality of longitudinally and laterally spaced printing domains (18). The machine (10) includes a plurality of spaced printing rolls (20a-20f) having parallel axes (22a-22f) and peripheral cylindrical surfaces (24a-24f) having image transfer regions (26a.sup.1 -26f.spsp.n.sup.f) adapted to print the imprints (12) onto the sheet (14). The rolls (20a-20f) each have circumstances (28a-28f) which are different integral multiples of the field length and which are not integral multiples of one another. Each of the cylindrical surfaces (28a-28f) has a subset of the image transfer regions (26a.sup.1 -26f.spsp.n.sup.f) positioned to print the imprints (12) on only a selected subset of the printing domains (18), the selected subsets of the printing domains (18) having a null set intersection. The rolls (20a-20f) are rotated about their axis so that the cylindrical surfaces (24a-24f) have equal tangential velocities. An image reproducing medium is transferred onto each of the image transfer regions (26a.sup.1 -26f.spsp.n.sup.f). The sheet (14) is moved longitudinally generally tangentially sequentially adjacent each of the cylindrical surfaces (24a-24f) at a velocity to match that of the cylindrical surfaces (24a-24f). The image reproducing medium is transferred from the image transfer regions (26a.sup.1 -26f.spsp.n.sup.f) to the printing domains (18).
