The Alpha Series by Matsui is a revolutionary 14 color mixing system in which all the water based colors in the system are Ready For Use. Not only does that mean they can be printed individually, Matsui has created the system to work directly with your Pantone Color Book to mix completely unique colors without needing software - making this system the quickest and most economical way to create custom colors. Alpha series inks can also be printed on top of a white water base ink or discharge underbase. You can also use this system on dark cotton fabrics by adding Matsui discharge agent into the ink at 3% to 5%.
