Izote Etching Inks,
made from a classic oleo-resinous copperplate varnish, are highly-pigmented inks with exceptional tonal range and density, especially well-suited to printing fine aguatints and photogravure. If the ink requires loosening, add just drops of a burnt plate oil or spike oil of lavender. For stiffening, magnesium or calcium carbonate should suffice. The inks are available in: Vine Black, French Black, Mars Black, Soft Black, Umber-bone black, Graphite Gray, Ultramarine Blue, and Transparent Base. All the inks have exceptional tonal range and can be extended for images requiring more transparency.
