Single-pass UV LED-curing inkjet ink debuts

Triangle Digital INX Co. (TDI), (San Leandro, CA) a member of INX Digital, teamed with LED curing specialist Summit UV in developing EVOLVE UV — a UV LED-curing ink that offers 4-color with single-pass through-cure at speeds of 80 ft. per minute or higher, running with Xaar 1001 piezoelectric printheads. No inert curing atmosphere is required.
“We’ve been working with LED-cure inks for some time,” said Ken Kisner, TDI’s senior vice president, CTO, “but at slower speeds. A key to this technology’s success is formulating EVOLVE UV to work with Summit UV’s unique, new LED. It has the ideal UV wavelength and, importantly, ample power.”

“Compared to conventional high-intensity LED lights,” explains Mario Carluccio of Summit UV, “our Black Diamond 365 Series has a shorter (365nm) UV-light wavelength and much higher focused outputs — in excess of 6.0 Watts per cm2. This enables us, with TDI’s specially designed EVOLVE UV ink set, to achieve through cure at far faster speeds than ever before.”

“We’re now breaking barriers to digital printing in several areas,” Kisner points out, “including short-run narrow web label printing, variable-data applications — and many more to come.

“Getting single-pass UV through cure in-line with one LED light at 80 ft./minute more than triples previous speeds. And it’s just the beginning. We [can] tailor EVOLVE UV inks for virtually any substrate — plastics, film, paper; even metal or certain textiles.”
