My work that is mounted on paper has a totally different process than the boards. I love printing photos on art paper as it gives the piece a more painterly look. Sometimes, I have to treat the paper so the ink will adhere to the surface. Then I oil paint it, carefully. This type is beautiful in a floating mounted frame. They do not have to have glass over them, since the wax protects the image. However, to keep them dust free, cover them with glass using a spacer.
