Epson UltraChrome GS3 ink is a 4th generation solvent ink chemistry developed by Epson specifically designed to increase overall color gamut while improving outdoor durability and colorfastness.  With the more aggressive solvent chemistry, these inks dry four (4) times faster than previous versions and offer same day lamination, just six (6) hours after printing.  These award wining inks have earned a Green Guard Gold certification for low VOC-emissions during printing and drying offering a cleaner, healthier print environment.
