On June 26 part of my demo for printing with the Gelli Arts Printing Plate included showing how to overprint on prints you're not too thrilled with. You really can get some interesting layers.
This first image is an example of that over printing. I had some checkerboard stuff and some circle stuff going on in the bottom layers. I put strips of cardstock cut with a decorative scissors on a plate "inked" up with purple and blue paint. And pulled a print.
Then I removed the strips of cardstock and pulled a ghost print, which you see in the second image.
When I've been home printing I've always cleaned the plate after each application of color. I would of course pull as many prints as possible, but then before doing a new design set up I would clean the plate.
Friends have been experimenting with letting paint sit on the plate to build up a patina (the older layers get somewhat reactivated and picked up by the fresh paint you put down). I decided it would be the perfect time to try it during a demo, so that we could all see the results together. In the second image you can clearly see the older paint from earlier prints coming through creating a very interesting texture.
I like both of these prints from the evening very much and hope to use them in my journal or paint on them outside my journal.
I could see artists who do ATCs or make cards having a blast with this printing plate.
