Collagraph printing

Collagraphy is a relatively new process in which a textured plate produces a layered print with various tones and often an atmospheric effect.
The process begins with marks, incisions, and patterns on a mount board.
Additional textures such as wallpaper, leaves, fabrics, tapes, stencils, and threads can be stuck down to create a composite image.
Carborundum can also be sprinkled over PVA glue to create a rough texture with lots of ink.
When the design is completed, the collagraph plate is varnished with Shellec to create a hard-wearing surface.
Once the ink is applied to the plate, a piece of loose fabric or scrim is used to rub the ink into the grooves and depressions and to clean the surfaces that form the lighter tones.
A piece of damp but not wet paper of around 300gsm is used. This will draw the ink out of the recessed areas of the plate.
Put the paper on the plate and pass it through the press. Then, remove your print to see the result! If the pressure is correct, you should see an embossing. Next, clean the plate, ink and repeat.
