Lascaux Plate-backing resist has been specially designed as part of the acrylic-resist etching system. This new generation acid resist is painted onto the back and the edges of etching plates to protect the metal from the action of the mordant.
Lascaux Plate-backing resist is water-soluble, ready to use, non-toxic and suitable for use on copper, brass, zinc, steel and aluminium. This red coloured resist is highly acid-resistant, durable and scratch-resistant. It may be used on unbitten or previously etched (e.g. aquatint, deep open bite) and is compatible with the other Lascaux resists and photopolymer resists such as Photec. The resist may also be used to create a variety of effects on collagraph plates.
