Anyone see these extra bits of photomask after developing?
http://www.delorie.com/pcb/inkjet/mask-bits.jpgThis is at 200x, the gap is only 6 mil. I've tried extra developing,
rinsing under high-pressure water, and scrubbing with a sponge. I can
get them out one at a time with a pin, but that's not an acceptable
solution. I'm even exposing a step less than usual in case it's from
a pinhole.

run a heat-gun-heated board through the laminator, it comes out all
bubbly and wrinkled.
