Wendy,
My process is similar to yours minus the acetate. I
plan to do a trial of two sequential prints from a
plate burner and flourescent bank. The plate burner
is 200 miles away, so it will be planned ahead. I
hope to isolate the problem from the suggestions from
you and others. Any great findings will come back to
the list.
Thanks,
Steve
