Abstract
Embodiments of a method of printing low volumes of paper bags on a digital printing press are provided. In the method, a plurality of orders are received. Each order includes a particular format relating to a bag size selected from a predetermined number of bag sizes and a graphic to be printed. In the method, the plurality of orders are organized into a plurality of batches. Each batch includes orders of the plurality of orders having a same bag size. A first batch is selected, and the graphic of the orders contained in the first batch is digitally printed on a first roll of paper having dimensions associated with the bag size of the first batch. The first roll of paper is fed through the digital printing press, and the digital printing press prints the graphic of each order contained in the first batch without stopping when transitioning between orders.
