Lascaux White Coating for Hard Resist

The Lascaux White Coating have been designed to be used in conjunction with the Lascaux Hard Resist. The layer of dry Hard resist is coated with a Lascaux coloured coating so that the drawing is highly visible. The white coating is analogous to the traditional lead white grounds. The topcoat is not acid-resistant and is to be removed with water before etching. After this, the plate can be processed with stop-out resist.
