Re: Pre-shrink paper for gum (oa to Katherine)

Differing observations under very different conditions. You're coating
paper in a room "beside floor to ceiling (north-facing) windows and under a
regular light bulb if the outside light is dim." I'm in a sealed darkroom
with two 100 watt bulbs. There's likely a huge difference in ambient light
levels between our two production areas. Apparently indirect daylight will
fog paper as your experience shows.

Great website & beautiful photos, thanks for the link!
