VARIABLE REPEAT PLATE AND BLANKET ROLLS

摘要

A printing press comprising a plate roll (20) and a blanket roll (21) mounted so that they are each individually removable from the printing press to allow a change of the print repeat size; an ink fountain assembly (10) that includes an ink blade (18); an ink train comprising a central distribution roll (12) disposed in adjacency to the ink fountain assembly (10); a first form roll (14) mounted in a first frame (40), the first frame (40) being movable to cause the first form roll (14) to contact the central distribution roll (12) at a different point in dependence on the diameter of the individually removable plate roll (16); a second form roll mounted in a second frame (42), the second frame (42) being movable to cause the second form roll (16) to contact the central distribution roll (12) at a different point in dependence on the diameter of the individually removable plate roll; and an adjustment assembly that is adjustable to move the ink blade (18) toward or away from the central distribution roll (12).
