Collograph prints are made from a collograph plate and are the reverse image of the collograph. Damp paper is placed over the inked collograph. A 'sandwich', of materials, protective paper, inked collograph block, paper, and felt padding are placed on a flat bed and a printing press is rolled over the top and a reverse image obtained.
Richness of colour may be added to the print by embelishing with a variety of materials including oil paint, oil sticks, metallic paint, and gold and silver leaf.
I often use the collograph plate as an art work in itself, because I like the three dimensional and tactile nature of the plate.
