These pigment inks are very different than their current line of water-based dye inks. They are slow-drying and are formulated to sit on top of the paper surface, giving plenty of time for blending and embossing. Dry time and permanence depend on the surface used—inks will dry faster and be more permanent on more porous surfaces. Use clear embossing powder or spray fixative for improved permanence. CP metallic ink cleans off stamps easily with just water, soapy water or stamp cleaner. If you get ink in the crevices of your stamps, you may use an old toothbrush to get them sparkling clean! As an archival, fade-resistant, and acid-free ink, they are an excellent choice for artwork and keepsake projects.
