In platemaking, a means by which multiple images from a single-image flat are exposed onto a plate in accurate register. For example, when printing labels, a large size stock may be used for printing which will contain several copies of the same label, which can then be cut into individual labels during finishing. Rather than create several negatives and image the plate once, a single negative can be made of the label and repeatedly exposed to the plate in different locations. Step-and-repeat can be effected manually or by a photocomposing device.
