I've been wanting to do this for a long time. Comfortable Shoes Studio had a great post (thanks!) that gave me the push I needed.
Plexiglass intaglio -
1st print - You can see I didn't clean the plate off well. I scratched the plexi with an old xacto knife. The ink, of course, was drying too fast as I didn't use/have any retarder. I do kind of like the "holey" look of the pear.
later prints: I used acrylic paint mixed with gel medium for this one. I like the way it is more saturated in some places. The second one is the ghost of the previous one.
Next I want to try some resist and actual painting/sketching into the paint on the gelatin.
