I used some 20 lb glossy paper that I got from a printer.They cut it to size for me. I made the copy on a Sharp color laser printer (real dark green). I cleaned the boards and wiped them with a blend of propylene glycol methyl ether acetate (PM Acetate from Diamond Vogel) and De-solv-it contractors solvent about 30% Pm acetate and 70% de-solv-it. Could use CitraSolv alone, but I couldn't get it out here in the sticks. Citristrip wipe-away works too. While the boards were still damp, I placed the copy on the board and ran it through the laminator twice, then into the oven at 375 degrees for 2 minutes and through the laminator again. soak off the image, and etch in 10% Bacquacil pool shock, 30% muriatic acid, and 60% water. I uploaded pics to the photos section under "big boards". This is the second time that I did this size boards, but the first time I silk screened them.
