Grain Mark Resist film is an economical translucent drafting film for creating hand-drawn or painted transparencies. The finely textured side will accept a range of drawing media such as chinagraph pencils, litho crayons, Indian ink and acrylic paint.
In addition all Lascaux Tusches can be used to create litho like washes. Drawn and painted marks can be further scratched into and digital and photo transparencies can be collaged and combined.
Degrease the surface with a little methylated spirit before drawing. You will need to test for the appropriate exposure times for your photo emulsion.
