RE: 1st temperaprint

Gord,

You might want to try just one coat. It has been a while since I did my
temperaprint, but I think the multi-coating refers to coating after each one
is processed.

Also, when you process it, unless the instruction has changed, you should
not use a roller. You use a paint pad (the kind that has thousands of short
hair), and you massage the print gently under water. It worked for me the
first time I tried it.

It could be underexposure too, but you can try a step tablet and overly
exposed it.

BTW, I replied earlier but used the address with sask in it, but the email
bounced.

Subject: 1st temperaprint

Hi:

Tried a temperaprint last night. blended an egg, added ammonium dichromate
(ratio 2 parts egg to 1 part AdC) added some water color pigment.

coated yupo - did 3 or 4 coats - letting it dry between coats, and then
exposed it.

Processed it by putting the print in water until the dichromate dissolved
and then put it in a tray with a sheet of glass on the bottom, added a drop
of dishwashing detergent and proceded to carefully roll a roller across the
print under water. Everything peeled up and floated away.
:(

I asssume the print was underexposed. In gum printing I can usually see
the image in the exposed unprocessed paper. I didn't see any image after
exposing the temperaprint.

Any other reasons for the image to peep away. Too many coatings?
Completely incorrect processing technique?
