Aiming for the highest print quality and lowest fluting effect as well as for a very good solid ink density (SID), the nyloflex FTL Digital can reduce operating costs and waste.
The very low durometer flat top dot flexographic printing plate is designed for printing on sustainable substrates with a higher content of recycled fibres 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 been troubled by the fluting phenomenon. 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.
It provides the possibility to use more recycled fibres in the substrate without sacrificing on print quality. Because of the combination of screens and solids on a single plate even on difficult substrates, it is possible to save plate material by up to 50% and reduce press setup time to register the plates. The inherent capability of the plate to form flat top dots with simple UV-A 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 of more cost effective liners.’
