roll on soft- and hardground - Graphic Chemical Crimson red no 1661

Applying the Etching Ground
Prepare and de-grease the plate. Mix the binder and the ink thoroughly on a glass plate. The amount of binder mixed into the ink decides the time required for hardening and drying. For fast-drying soft and hard grounds the mixture contains 1/3 binder and 2/3 ink, which will harden after approximately 20 minutes in the drying cabinet. Without the binder, the etching ground takes five hours to harden. The result after mixing must be a thick, even substance which does not curdle.
