ABSTRACT:
A method is provided for applying a watermark pattern along a length of photosensitive medium, the photosensitive medium having a frame pitch in the length direction that is the sum of an image frame height plus an interframe distance. The method exposes watermark tiles contiguously along the length of the photosensitive medium, wherein each watermark tile has a height dimension that is an integral divisor of the frame pitch.
