This new-generation acid resist has been specially designed as part of the acrylic-resist etching system. The lines and marks which can be generated by using the Lascaux Hard resist are comparable to those offered by traditional hard grounds. It is painted on the plate in a thin even layer which when dry can be drawn into with etching tools. As the waxy resist allows free movement of the etching needle, delicate line drawings can be made. The resist may be used in its clear form or coloured after application. Broader open marks can also be created in the layer of resist.
Lascaux Hard resist is water-soluble, ready to use, nontoxic and suitable for use on copper, brass, zinc, steel and aluminium. Plates should be correctly prepared, whether unbitten or previously etched (e.g. aquatint, deep open bite). The resist is highly acid resistant and durable. It is compatible with the other Lascaux resists and photopolymer resists such as Photec. Lascaux Hard resist may also be used to create a variety of effects on collagraph plates
