Union Ink Co has focused on manufacturing newer and better screen printing inks since its founding in 1931. For over 80 years Union has continued to develop new inks for the screen printer. First with Hot Split Transfer Inks which revived a very dormant Transfer Industry; first with NYLOBOND, which took a good deal of fear away from printing Nylon Windbreakers; and with Tru-tone Process Colors the standard for 4-color Screen Process Inks, making a 4-color process print more true to life. We have continued to be a leader in the screen print industry with our development of other great products such as: Flash-back Reflective inks and High Square High Density Colors. Union continues to introduce new special effect inks into the T-shirt market. Union manufactures a wide range of products including, what we know are, the best textile printing plastisols on the market. From the general purpose PLUS series to the highly acclaimed MIXOPAKE Pantone color mixing system, you can count on high quality inks supplied from over 75 national and international dealers. We support our customers with helpful technical support and quick delivery using a network of dealers around the world. This website is designed to offer you as much technical information and health/safety information about our inks as we can.
