Hartness International’s Uvaclear™ is a line of organic inks for direct-on-glass container screen printing.
Uvaclear inks are “ecologically friendly” and ultraviolet curable in about a quarter of a second. The inks are initially being marketed to beer, beverage, wine and spirits packagers and the glass container suppliers who serve them. Compared to ACL (Applied Ceramic Labeling) and other organic inks, Uvaclear can improve productivity, as bottles can be immediately handled after screen printing. Additionally, the organic nature of the ink makes it suitable for recycling because it is burned off during the recycling process without contamination. Hartness has formed a new division, Hartness Inks, to further develop the inks and expand their markets.
