Sheetfed Drying/Curing — No Limitations

New Generation Dryer

technotrans has also introduced a new generation, thermal drying system designed to provide the highest levels of ink- and water-based coating drying at maximum rated press running speeds. The system is configured to provide drying starting from the first sheet of the delivery, and its design allows complete interchange ability with IST UV components.

One of the biggest questions is whether the dryer can actually perform its duty on a given substrate, according to Chad Carney, director of marketing communications for Research Inc. “When they’re printing on gloss stocks or nonporous materials with their standard printing system, they’re typically using a water-based ink and they’re not going to dry on a nonporous substrate,” he says. “So when they’re looking to add the dryer, in that case they don’t have to switch their ink or use a solvent-based ink, so they can achieve a faster drying time.

“With our infrared systems, they can simply add that on to their sheetfed press or their mail base if they’re doing direct mail. They don’t have to make any changes to their existing equipment—just an IR dryer behind the print station.”

Models 5060 and 5061 are the latest additions to the Speed-Dri IR drying system line. The 5060 dries a 4×10˝ path with one module or an 8×10˝ path with two modules with four kilowatts of voltage. The 5061 can dry print target areas up 4˝ wide.

When printing on plastics, conventional inks give way to UV inks, which provide an instant cure, notes Elinor Midlik, president of Prime UV Systems. “Because you’re installing it in the sheetfed press after each color unit, one of the characteristics that you’re looking for is a very compact system,” she says. “Another quality is a cool UV system that will not heat up the press.”
