We are the exclusive distributor in the United States for a true NanoColorant water based ink that is used for Espon, Mimaki and Mutoh print heads. The manufacturer of the inks is Yuhan-Kimberly. We offer the ink in 220ml cartridges and 1 liter bottles. Because the ink is a true Nano, you get more color in each drop and more coverage per square yard. Besides CMYK we offer gray, red, violet and orange. Price per liter is $230. Please contact me if you would like to purchase a 220ml sample set to test. Our inks have been tested and passed for the new children regulations. Customers are averaging 1,500 full coverage prints on t-shirts with their direct to garment machines per set of CMYK 1-liter bottles. You will not believe the difference a nano makes.
