All objects intended for recognition (boxes, text items, bar codes) must be inside a quadrangle formed by the centers of the synchronization marks. The distance of these recognized objects from the closest wall of this quadrangle should be at least 5 mm. The distance of the text from the frame is at least 1 mm (i.e. 8 points). The distance of two neighboring boxes must be at least 2 mm (i.e. 16 points) to avoid confusion.
