STUTTGART, Germany—Flint Group recently launched nyloflex FTL Digital, a very low durometer flat top dot flexographic printing plate for printing on sustainable substrates with a higher content of recycled fibers and other paper and board applications in combination with water-based inks.
The core advantage of this new plate is the out-of-the-box reliable performance in fluting reduction in corrugated post-print, e.g. delivering a very appealing print performance on substrates like uncoated test liners or kraft liners in combination with a B flute.
From the beginning, printing on corrugated board has had the problem of fluting. Apart from other factors, the liner quality is one influencing variable. Another one is the dot shape of the printing elements on the flexo plate. “Flexographic plates with flat top dots, in contrast to common digital plates with round top dots, can reduce the unwanted fluting effect,” explained Dr. Eva Freudenthaler, VP technology at Flint Group Flexographic.
Aiming for the highest print quality and hence lowest fluting effect as well as for a very good solid ink density (SID), the nyloflex FTL Digital is reportedly able to reduce operating costs and waste. It provides the possibility to use more recycled fibers in the substrate without sacrificing on print quality. Because of the combination of screens and solids on a single plate even on difficult substrates, Flint Group says it is possible to save plate material by up to 50 percent and reduce press setup time to register the plates. The inherent capability of the plate to form flat top dots with simple UVA tube exposure keeps the plate making process simple and cost effective as neither extra steps like plate lamination nor extra consumables or special FTD exposure equipment are required.
“Since the launch of the nyloflex FTC Digital in 2017, we already offer a valued flat top dot plate to the corrugated post-print market. It has proven to be very versatile with respect to substrates that it can cope with, delivering excellent highlights in combination with good fluting reduction. Due to its higher durometer it naturally reaches its limit though at the lowest end liner qualities,” explained Dr. Freudenthaler. “That is why we have supplemented our plate portfolio with the nyloflex FTL supporting the continuing trend to more cost effective liners.”
