A method of automatically placing N-up images for imposition on media sheet for printing in which, for a user selected value of N, the co-ordinates of the sheet cells are determined and stored; and, the co-ordinates of the media, trim and bleed boxes of each of the images is determined and stored. The user selects, from a menu, a desired set of alignment rules and the system then compares the location of the appropriate bleed, trim or media box with the sheet cell boundaries and shifts the images and automatically locates the selected box on the sheet cell for the desired placement. The method is particularly useful for eliminating the template making in large print jobs for roll fed presses.
