Re: [BKARTS] laminating cardstock question

I would add (clarify) that the core sheet does not receive any adhesive --- only the outer layers are glued, and thus, should provide a flat board.
Also, a nip in a press is useful, but drying in a press is not needed ---- drying between absorbent boards and under a weight is sufficient.

I understand that you need to change the direction of the paper so that the grain crosses, like plywood. Otherwise, the law of opposite pull needs to be observed. The basic rule of covering boards, (in this case the central sheet) is that you match any attachment with a similar one on the opposite side. The final board will then be either 3, 5 or 7 sheets. Use a foam roller to get an even coating on each sheet and rub down with waxed paper. Try a small group of sheets and nip them to check the procedure.

Good  luck.
(remember, odd numbers of sheets, and the core could be board)

For the recent Marking Time exhibition, I originally intended to laminate 6-8 sheets of Fabriano Ingres paper (160 gsm) together to form the boards. The paper is so nice it wouldn't need covering, only decorating. Single sheets lay on the table with a slight curve along the grain. I tried laminating 2 sheets at a time and 8 sheets at a time. I tried flipping the natural curve on every other sheet. I tried pulling out the curl with the pull from the next sheet. I tried PVA/MC and a mixture of same with wheat. I also tried Yes paste, which while adding the least moisture and frankly my flattest boards, was also the most messy. I tried letting the paper relax and I tried sticking them together right away. I even tried cross graining a few sheets in the stack (which only introduced other complications). After several days in the press, my new boards appeared to come out flat but would also end up with some curl after a day or so.

Any suggestions?
