DuPont Cyrel® Solutions introduced the new Cyrel® Lightning UV-LED optimized plate family to the market at the INFOFLEX 2021. The first member of the new Cyrel® Lightning photopolymer plate range, Cyrel® LSH, reduces access time by up to 42% and is available in 045 and 067 gauges. It is solvent processable and comes with certified exposure recipes in the latest software of the Esko XPS Crystal units on the new printing plate. Ideally suited for advanced surface screenings, Cyrel® LSH is introduced as a hard durometer plate with a smooth surface optimized for a wide range of substrates and printing processes in flexible packaging, label and paper printing applications.
Exposure settings on LED units often have to be adjusted for either higher quality or shorter access time options. Formulated from the ground up with UV-LED exposure characteristics in mind, Cyrel® Lightning plates offer a solution for this. The new printing plates optimized for these systems such as the Esko XPS Crystal, in order to to make full use of these systems’ capabilities, offer various advantages. These include a further optimized match between access time and plate performance while not compromising the print quality.
A balanced cure is possible with DuPont Cyrel® Lightning plates
DuPont Global Technology Leader Suniti Moudgil said that Cyrel® Lightning plates use chemistries with tailored UV profiles to achieve tunability between surface and through cure. Noting that this innovation enables a balanced cure that can be tailored to the unique dynamics of a scanned LED exposure sequence, Moudgil also stated that this provides sufficient through cure using a finely tuned UV absorption profile.
Cyber Graphics, a tradeshop from Memphis, Tennessee, was one of the pioneers in adapting UV-LED technology in the prepress operation and has been involved early during the external evaluation of the new photopolymer. Cyber Graphics Vice President Kevin Bourquin said; “In flexo, we constantly talk about driving process optimization. So, having a plate that is tuned for LED exposures, driving throughput, not having the exposure be a bottleneck with LED technology, while still delivering the printing quality that we expect, was a great benefit to our business”.
