A device for stacking selected sheets in an offset manner so as to facilitate print quality measurements. Certain sheets are automatically or manually selected to be offset deposited onto a stack of sheets so that an edge of the selected sheet including a number of printed measuring fields extends beyond other sheets in the stack. A measuring head transversely scans the measuring fields of the selected sheet for print quality measurements while subsequent sheets are stacked in the ordinary manner. Since subsequent sheets do not cover the extending edge of the selected sheet, sufficient time is provided to complete the scanning operation with a single measuring head without interrupting or slowing the normal stacking rate.
