Flint Group Narrow Web introduces CombiWhite rotray screen ink.

Flint Group Narrow Web announced the introduction of an upgraded version of CombiWhite, the easy over-printable opaque white rotary screen ink used in beverage, health and beauty, and no-label-look applications.

"A classification and labelling change led by REACH resulted in Flint Group, as a responsible supplier, deciding we could no longer use N-vinyl caprolactam (NVC, CAS number 2235-00-9), in any of our products," said Jennifer Joyce, global product director. "While EuPIA has initiated a prolonged substation process until March 2015, we are pleased to announce we are ready with re-formulation work and have had 15 clients using the new product for well over five months; furthermore, we have not had one single negative report from any of these tests."

CombiWhite C3 is designed specifically for combination printing with all narrow web ink technologies and can be used on all types of substrates. Printers will experience perfect combination print results with virtually any print process such as UV flexo, UV offset, UV letterpress, UV screen or water-based flexo.

"The whole aim with this reformulation is that no one should notice any difference between existing formulations and the new, upgraded, CombiWhite C3," added product manager Par Olsson. "It is one of those few cases where you are happy to hear there is no difference between the new product and the previous one."

Through historically conducted customer interviews, Flint Group identified 15 performance attributes important for all types of combination printing with screen white inks. The top rated five are: opacity, flow-out (pinhole free), adhesion, printability of overprinting ink and cross hatch resistance.

"When formulating an opaque white screen ink, one is really trying to combine some extreme, almost conflicting, print proprieties," Olsson said. "The ink should be capable of performing at high speeds with free flow, no pinholes in solids, and with extreme sharp text; at the same time it should be easy to overprint.

"We have several clients using CombiWhite C3 on no-label look for beverage labels as well as cosmetic labels," Olsson continued. "These end applications do possess slightly different challenges but, through our formulation expertise and in-house print testing capabilities, we have managed to optimize press performance with the most stringent end use demands."

"We know that several of our clients are pleased with Flint Group taking the lead and formulating products that are exceeding regulatory demands," Alan Day, Flint Group UK business manager, said. "Our clients rely on us as their ink supplier that we use products that are in accordance with EU law. They all see it as a great benefit to them that their workers, as well as their clients, know the labels and packaging supplied by them are complying with state-of-the-art regulatory demands."

"We understand fully the aspect of printer safety, and care for our staff," said Jean-Francois Clisson at APE Etiquettes, France. "But safe products should still provide superior performance attributes. We have been running the new CombiWhite C3 under an experimental code for well over three months and we see not a single defect; in fact, we believe flow-out has slightly improved. For us this is an easy switch and win-win for all involved."

Initially, CombiWhite C3 will be commercialized in Europe as the regulations have been implemented in this region. It will be available in the same sets of press ready products optimized for no-label look applications that were previously available. New products are subject to a product code change:

* USW90005 replaces USW90001.

* USW90006 replaces USW90003.

Effective immediately, CombiWhite C3 is available across all Flint Group Narrow Web distribution channels and, from this date, Flint Group will no longer supply inks containing N-vinyl caprolactam in Europe.
