Sinclair Ashman

Collagraph printmaking demonstration: Sinclair will demonstrate how he inks and prints his collagraph printing plates to create rich, textured images. The collagraph technique is all about the use and control of texture to produce lighter and darker areas in the print. Combinations of rougher and smoother materials are stuck to the surface of a board (the plate). Rougher areas hold more ink and therefore print darker. Smoother areas hold less ink which is more easily wiped away, producing lighter areas in the resulting print.

He uses birch plywood as the basic plate material. After sealing the surface with varnish and allowing it to dry, the materials are added to the surface. Sinclair often smears acrylic gels such as pumice gel or crackle paste around the plate surface, or carves into the material using plastic or metal tools, whilst fabrics and other materials can be pasted directly onto the surface. Additionally, he uses gritty carborundum powder (used commercially to create sandpaper/glasspaper) to create texture in specific areas.

Sinclair will have examples of finished plates and plate materials to see and touch. He will also answer any questions you may have about his practice, techniques and creative inspirations.
