Atelier inks have been developed with water coloring in mind, to work seamlessly with Fadeout No Line Coloring Ink. They are more in line with a high end watercolor paint. They stamp beautifully, can be used to create beautifully blended backgrounds, and are Alcohol ink and marker friendly (when dry or heat set). A buttery consistency, with a very high (color) pigment content, better blend-ability and layering properties. Add water to Atelier for painting and color stays bright even after it dries, plus some beautiful undertones will emerge in, giving more artistic dimension. It's a different way of using and thinking about ink. Artist grade quality. Water reactive, fusion ink, acid free and archival.
