High end, wide image latitude sheet photopolymers for Digital flexography similar durometer range as #1 above but thermally developable. Formulatory approaches designed to give good image latitude, good cleanout without blotter marks. Thermally developable Digital plates are considerably more environmentally friendly than solvent-developable as well as much safer in the workplace

Both “Capped” and “Uncapped” FTD Digital technologies using an innovative UV activable oxygen barrier and Digital tandem coating for high end FTD digital plates. Concepts similar to Cyrel Easy ESP (Capped) and Flints Nyloflex FTF (Uncapped)

Surface textured (rough) Image Contrast Cap Layer on Carbon Black based Digital tandem coatings on PET substrates used for manufacture of high end Capped Digital Plates for improved image fidelity and ink transfer

High image fidelity UV ink resistant medium-hard durometer Digital flexographic printing plate similar to MacDermid’s UVR and Cyrel DFUV for use in labels, folding carton, flexible packaging etc.

High end, wide image latitude sheet photopolymers for conventional or analog flexography. Similar durometer range as #1 above and as needed in the market

Liquid Photopolymer for flexographic printing both softer durometer version (Shore A 33^o -36^o, Shore A 25^oand Shore A 18^o) for the Corrugated market, harder durometer version (Shore A 50^o-55^o, Shore A 60^o) for the Book, Stamp and Multiwall Bag market and Hard Durometer Photopolymer Molding Resin (Shore D 55^o / Shore A 95^o)

Carbon Black based Digital LAMS coatings on PET substrates for manufacture of uncapped Digital Plates. Coating is solvent-based and designed for optimal CW/OD, efficient laser ablation and flexible, for plates of all different gauges

Photopolymer formulatory approaches and processes for Continuous In-The-Round (ITR) Photopolymer Sleeves. Continuous ITR Photopolymer Sleeves are preferred because it offers distinct advantages such as potential for continuous seamless printing (wallpaper etc.), minimize cupping and distortion, near perfect digital registration, eliminate plate mounting and which perfectly fits into the digital process, among other advantages

Solvent coated UV curable acrylic, non-blocking adhesive backing polyester substrate for both Liquid and Sheet Flexographic Printing Plates having outstanding adhesion of both SIS and SBS based photopolymers to primed Polyester backing substrates

Water borne UV curable Polyurethane based non-blocking adhesive for sheet flexographic printing plates having outstanding adhesion for both in-line and off-line coating
Water borne, non-blocking adhesive based on PVDC acrylic latex for sheet flexographic printing plates having outstanding adhesion for both in-line and off-line coating

Processing solvent as a replacement for Perchloroethylene / Butanol for processing of sheet photopolymer flexographic printing plates similar to Cyrel Cylosol and Flint’s Nylosolv A. The newer solvents are significantly more environmentally friendly than Perc/Butanol and also much safer in the workplace

UV/EB cure is an enabling technology with endless possibilities. UV/EB offers various advantages such as increased speed, improved productivity and lower costs, environmental compliance (VOC and HAP), minimal toxicological effects, improved adhesion to “difficult” substrates, improved properties such as scratch resistance of the cross linked coating, possibility of allowing “Smart” coatings and ideal for heat sensitive substrates. Some of the projects of interest are summarized below.
