Run the 3D paper sculptures in a printing press, on the bed and under the drum three or four times to get it really flat. For less flat design purposes, I use my car to roll over a sculpture nestled between sheets of plywood. I have also pounced upon the sculptures in my studio using my feet.
After flattening and before inking I seal the paper template so as to provide longevity.
I use Akua soy-based inks and 18-inch rubber brayers to apply multiple colors to the template before running it through the press onto white paper.
Here you see an already inked-and-printed template.
On Sensations of Soaring Exhibition page you can see several of the beautiful prints I have made using this process.
