Acrylic Artists Ink has been formulated with artist pigments, chosen for their permanence, maximum stability and degree of light fastness, dispersed in an 100% acrylic emulsion with a viscosity of 40-200 cPs. The colours are very fluid, and dry to a matte, permanent finish. Acrylic Ink can be applied with an airbrush, brush, and technical pen; the colours are used with rubber stamps and markers, and are the perfect medium for dripping-pouring techniques, for calligraphy, and for stencilling, printing and painting on textiles. , , The inks are acid free and are ideal for scrapbooking and retouching photographs; all the colours dry waterproof, do not yellow, resist ultraviolet light, and can be mixed and combined with our mediums and textures, or diluted with water to obtain watercolour effects. Acrylic Artist Ink conforms to the European Security Regulations and Environmental Standards of the REACH Protocol and to the EN 71-3:2013 standard.
