I'm certain thats doable, but is there a guarantee that the watermark is in a fixed location? I would think the software would adjust placement to avoid being drowned out by blocks of yellow, etc.

Additionally, if the tracking dots use a specific shade of yellow, they could identify others that aren't the same shade. Still, I guess you could test the shading or placement theory easily with several printed examples.
