Abstract: A printing method and apparatus for printing different indicia, such as account numbers, on selected documents without changing plates or stopping the press during a press run. Different indicia are provided at two or more lines on a printing plate, each line being separated from an adjacent line on the plate by a predetermined distance relative to movement of the plate in a press. The plate transfers images to a blanket having a region that does not contact the plate and thus receives no image of the plate area that registers with the noncontacting region of the blanket. The plate and blanket initially are aligned so that the noncontacting region registers with one set of indicia on the plate, so that the blanket receives a partial inked image lacking that indicia. That partial inked image is transferred to sheets passing through the press.
