- Everything I have see so far is either expensive or hit and miss.
-
- Mussings follow.

- When used with a laser printer paper will pick up more tonner then plastic
- and makes for a denser mask. I used a very light cardboard stock.
- To remove the paper I soaked it in water for a few hours and then
- rubbed the stock with my fingers to remove the fibers not attached
- to the mask. When I finished the mask still had paper fibers stuck
- to it but it etched ok. I rubbed a bit to hard and pulled of some of
- the mask. Still a bit on the iffy side but I think it shows prommise.
-
- If anyone knows of a better way to get rid of the paper we might have a
- process that is not hit and miss. One thing I did not try was burning
- the paper. Perhaps if the paper and board were baked in an oven the
- paper would turn to carbon and could be washed away. I am not sure if
- it would ruin the mask.
