Sun Chemical unveils water-based ink

Sun Chemical has unveiled a waterless, water-based sheetfed offset ink for use on Heidelberg's Quickmaster digital presses.

Sun Chemical has unveiled a waterless, water-based sheetfed offset ink for use on digital offset presses.


It developed Instant Dry W2 in conjunction with Heidelberg specifically to work on the Quickmaster DI press.


The two companies have worked in tandem on the project for over a year.
Sun Chemicals product manager for sheetfed offset inks, Horst Zuckerstatter said that the new inks would offer higher quality and help the environment. Using these inks can help printers virtually eliminate all volatile organic compounds in the pressroom, he said.
The ink was shown at Drupa in Heidelberg's "concept studies" area, which showcases potential future product. The ink is fast-drying, with sheets described as "cuttable within 20 minutes", and can be washed up using just water and soap. "It's not as temperature-sensitive as normal waterless ink, either," said a Heidelberg technician. It is expected to become commercially available within a year.


Sun Chemical has also developed waterless inks for use on conventional sheetfed presses. unlike Flint Ink's recently announced Single Fluid Ink, which works with conventional plates, they use waterless plates and need on-press temperature control to maintain the required ink viscosity.


Sun Chemical has also been demonstrating its range of UV-cured high-gloss inks. The manufacturer said that Hy-Bryte achieves a 85-90% gloss compared to 60-65% for conventional offset inks, without the need for dry back. Fabrice Bourgeois, general manager for energy curable products, said that the system could save sheetfed printers time and money by allowing them to produce a high-gloss coating while on press.


Hy-Bryte runs like a conventional ink and requires no primer coating or special rollers and blankets. However, the system relies on one or two UV lamps between the last printing unit and coating unit.
