Printing marks on substrate edge

Abstract

A system (10) includes a printing assembly (13) and a stacking assembly (59). The printing assembly (13) is configured to print: (i) multiple images on multiple respective substrates (50), and (ii) multiple marks on one or more edges of the multiple respective substrates. The stacking assembly (59) is configured to stack the multiple respective substrates on top of one another to form a stack (88) having a top surface (32) parallel to one or more of the substrates, and sides (21, 31, 41, 51) made from the stacked edges of the substrates. One or more of the marks are visible on a side-view of at least a given side (21) of the sides, and at least a position of the one or more marks in the side view of the given side, is indicative of a problem that occurred while printing one or more of the multiple images.
