Papers

This is where you'll learn just how good your Karma is. Perhaps one of the most important things is the surface we print on and guess what, it's one of the ones we have the least control over. You'll learn paper manufacturers don't like us. We do things to their papers that show every minor change they make, and I have yet to find any sympathy from them. Good luck!

ALL PAPERS MUST BE CHECKED FOR "BLACK SPOTS" IMPERFECTIONS IN PAPER- INSPECT BY TRANSMITTED LIGHT. Try cutting paper so they end up in shadow areas of print becouse they will show in the final print and etching them out is a pain- if possible at all. A beautiful print with a big black spot in an otherwise flawless skin can really make me cry.

Some papers I have worked with:

Right now my paper of choice for warm images is:
Rising Artist Drawing Bristol 2 ply velum good very warm tone - stains warm in hydrochloric acid.
ABOVE PAPER IS VERY FINICKY SEE SPECIAL CLEARING BATH FOR "PINK" PAPER PROBLEM. Also becouse it is two ply it sometimes gets bubbles between the plys, this will come out after washing by placing paper face down on blotter paper covering with blotter paper and using a roller squeegee to gently push the bubble to the edge of the paper and out. BUT the last 2 batches of Rising I've gotten seem to have a different glue and are totally separating in the wash. With utmost care I can keep it together. Who knows about the next batch.

Cranes 100 % rag marker 13.5 lbs (tissue) - Bostick and Sullivan sells it

Cranes kid finish stationary 22 ½ x 30ish or 8 ½ x 11 - Bostick and Sullivan sells it

Cranes "Platinotype" warm tone cover stock crest natural white wove 90 weight 23x29 11 ½ x 14 ½ - Bostick and Sullivan sells it

Arches Platine this paper is said to be designed for our process cold tone be careful with tween 20

Stonehenge comes in various shades natural white can be very nice.

There are so many possible surfaces to coat on. I once made some great prints on smooth pieces of sandstone!

Remember do not cut paper with razor blade and metal ruler! Most printers rip their paper to size with a metal ruler. The razor blade and ruler will cause small specks of metal to cover your paper and cause tons of black spots.
