can you use these pens with acrylic paint and ink?
The Pebeo Drawing Gum Pens are designed to mask of areas of a painting which you want to retain the colour of the surface.
The Drawing gum pens put down a very thin layer of drawing gum which means it works best with best with Watercolour and diluted Gouache.
The product can work with Acrylics and ink, but these will need to be diluted so it has a thin constancy, thin enough to be able to peel off the Drawing Gum.
Acrylic can be too thick and opaque therefore will cover the masking fluid making it difficult to remove. Also, Acrylics dry to a permanent waterproof finish which may make it difficult to remove the thin layer of masking fluid.
The success with using Masking fluid and inks will differ depending on the inks use. Acrylic inks are fairly opaque and again may cover the thin layer of masking fluid. Diluting these to be more like watercolour may offer more success.
I have had success with alcohol Inks on Yupo paper as the ink is fairly thin and allows you to lift the masking fluid when dry.
Hope this information helps
