Innovations in Printing Ink

Nature’s Nation was printed with an HUV (hybrid ultraviolet) press, which uses even less energy than a conventional UV press since the UV light is used only once, rather than at separate stations for each color of ink.

The ink on a page is a complex medium composed of solvents, pigments, dyes, resins, lubricants, solubilizers, and surfactants. As the result of efforts within the printing community to reduce the use of volatile organic compounds (VOCs), some companies have begun using UV (ultraviolet) inks. These inks use only minimal amounts of VOCs and are cured instantly by exposing them to UV light, making them less prone to scratches, scuffs, or ink transfer, and thus leading to far less paper waste than when conventional inks are used.
