The Alpha Series from Matsui is a water based ink mixing line that is designed to be used with your PMS (Pantone) color book. Mix any PMS color using these primary colors by following the color percentages found on any PMS swatch in the book. These inks can be printed directly to garments right out of the box, but are designed to be mixed together to achieve any PMS color without the need for additives or bases. Have questions?
