Re: Need Advice on Thick Gum Coating

Katharine,
I use brush to spread the mix quickly and then dry, or almost dry foam
roller to smmoth the coat. I use foam roller that Clay has suggested a while
back. If you get too much gum on your roller then it is difficult to smooth
out even. If you keep overworking it you weill get unven coating as well. It
is not difficult after some practice.
As far as the exposure through the back of the glass, a colimated light
source is required, so that the image is not blurred out. I do not have one,
sun exposure is my option. I have not printed in the sun in ages.
