And yes you would probably see the squares in the black over the red and white rectangles. We force black overprint on text that is 12 pt. and smaller and force knockout under anything larger than 12 pt.
Agreed. Although we have set our auto-tolerance for black overprint to 24pt and below. All depends on the artwork, but this has worked well for my (employers) shop.
