Woodruff Printing–Scaling New Heights With UV

Brent Woodruff was tired of turning down large jobs. If a publication required more than 30,000 copies or was larger than 32 pages, he had to decline the business. And he was tapped out in terms of sales. With his presses running 24 hours a day, he couldn’t fit in any more jobs. As vice president of operations for Salt Lake City-based Woodruff Printing, he was taking care of his intermountain service area with his sheetfed presses, but couldn’t expand in any direction, geographically or product-wise.

Woodruff was keeping his ear to the ground, though. He kept reading about UV printing in trade magazines and hearing about other printers that were adding UV printing to their mix of options for customers. In 1998, he decided to take the plunge by installing an eight-color Sanden variable-web press with UV capability.

“When we put in the Sanden web press, that was a big jump for us,” Woodruff says. “We had been primarily a high quality sheetfed printer for many, many years—the company was started by my dad in 1956. When we put in the Sanden press, that was a risk. It’s a different animal. But the biggest thing for us was the UV capability.”

Woodruff Printing’s web press is equipped with 10 Prime UV lamps for inter-station drying, supplied by Prime UV Systems. The eight-color press has a Prime UV lamp after each printing unit, plus extra Prime UV lamps after the fourth and eighth units for “the little extra drying” that assures a speed of 1,200 fpm.

With the Prime UV lamps, the company’s ability to turn around jobs for its customers tripled. Woodruff’s sheetfed presses run an average of 10,000 sph with only one side printing per run and a mandatory wait between runs for the ink to dry. The Prime UV-equipped web press runs at about 30,000 sph on both sides simultaneously, the ink comes off dry and the sheets can be fed immediately into the bindery.
