Some notes on this process:
- Wet paper and leave to dry until most the surface water has gone but the paper itself is still damp and flexible. Use a heavy (thicker) paper that can take some abuse.
- The plates I used were some scrap copper. Any hard surface will do.
- The pasta machine I have can vary the gap between the lasagne sheet rollers. Even so, I had it set to the widest gap to take the paper, plate, plastic and felt.
- Acrylic paint dries very fast. Using an oil paint would give you more time to work. However, you get very nice clean prints using acrylic as there is no wet residues left on the plate between each print - meaning you can get areas of the print which are just the paper showing through with no other marks. Oil tends to leave a subtle staining unless your plates are well cleaned between each print.
- I sandwiched the paper and plate between a piece of polypropylene plastic (the type used for stationary boxes) and felt. The plastic guides the paper through the rollers. The felt helps the rollers climb over the edge of the plate. Without the felt the roller just collides with the lip of the plate edge and drags.
