I coat my paper under the light of a 60 watt incandescent bulb two feet
from the surface of the paper. Many of my negatives have a rubylith "mat"
around them to make a clean edge and not show brush marks. Naturally the
coated area around the print is larger than the image, and it clears paper
white, showing no evidence of fog. Also, to address the sub-threshold
exposure question, the prints and step tablets show clean whites also
where they should be. Maybe something else is amiss with Jeff's
procedure. Oh , and I leave the other incandescents on in the darkroom
while coating.
