Drying/Curing Equipment — Avoid Half-baked Systems
Prime UV Perfection dryers are designed to cure UV inks at speeds up to 2,000 fpm and are intended to replace hot air, gas-fired ovens on perfecting web presses. Prime Perfection dryers are controlled by the Smart 2100 control platform, which gives the press operators total control of all aspects of the UV printing system.
Because more printers are doing multicolor work, dryers are becoming necessary for faster turnaround times and higher quality printing, according to Margaret Bain, marketing coordinator for Accel Graphic Systems. Drying systems reduce spray powder usage and setoff or blocking.
"The fastest growing curing and drying technology is probably UV," she says. "Ultraviolet inks and coatings produce bright, intense colors and extremely high gloss."
Accel Graphic Systems manufactures the Tempest hot-air dryer. The Tempest uses PTC thermistors instead of IR elements to accelerate the drying process. The compactness of the delivery area in low-pile presses makes IR drying more problematic because of space, excessive heat and premature wearing of parts, according to Bain. Many of the safety features found on larger IR units are not available on smaller format presses.
Keith Tap, vice president of technical services for Grafix North America, finds that printers are looking for an integrated system for drying and curing that will produce printed products that broaden their market advantage, while delivering consistent results. "The only way to ensure complete success is to provide a system that incorporates state-of-the-art hardware, an organization of parts and service support and, most importantly, hands-on application training after installation startup with continuing after-sale support," he says. "Grafix North America provides focus on the latter by providing its own staff of application and in-field demonstrators dedicated to this process."
Drying Hybrid Inks
The company's award-winning process, CoCure, allows printers to achieve the benefits of UV gloss, curing of hybrid inks on absorbent and non-absorbent substrates—such as static cling, styrene and foil—in-line without the need of a fully dedicated UV press.
