Two friends and I tried Gelatin Plate prining last week.Here are mine drying in the studio bathroom.
This one is more subtle but still visible.Sheet music made a good background as long as we didn't make the paint too dark.
I still prefer monoprinting for a similar effect with less mess. I don't like the pieces of gelatin that get everywhere as the plate breaks down.
For those who haven't tried this technique, you make the gelatin plate using clear gelatin-basically jello without the color or sugar. We found that it needed to be unmolded from the pan to make a good print. We also found that a thicker plate worked better. It didn't break down as much if that is the effect you want, but it made a clearer print.
