Figure 1 Digital Plate Ablate Image LUX Lamination LUX Membrane Expose Solvent Process LUX Digital Platemaking Workflow Remove Membrane FTA TODAY • All existing digital flexo plate imager types and sizes. • All current flat exposure systems. • MacDermid Digital MGC, Digital MVP, Digital MAX, Digi- tal Rave and Digital Epic plates. • AM, FM, Hybrid and Esko HD screening methods. • Surface/solid ink density enhancement technologies, such as EskoArtwork’s Microcell. The LUX process is meant to complement an existing digital flexo workflow, not replace it, and will permit the use of legacy artwork without modification for as long as the customer desires. The mem- brane lamination itself takes only 5 minutes. MacDermid also devel- oped a protocol to help users adjust prepress and gain curve to achieve their desired color management targets and get the most out of LUX technology. The protocol is comprised of three steps, as follows: • One-color print test to define the print gain curve and the needed cutback curve. • Four-color print test to verify the cut- back curve and define the color space with the LUX plate. • Full production jobs with optimized prepress and print conditions. Benefits for Printers and Platemakers Both printers and platemakers will see improvements when using the LUX platemaking process. Printers can obtain high- er line screens with no changes in print equipment (although line screens higher than 175 lpi benefit from adjustments in anilox volume) and produce smoother vignettes, and corru- gated printers will see less fluting in printed screens. Plate- makers will see greater consistency and more predictable and reproducible plate quality. The LUX process also offers extended gamut in that it grants platemakers another six to eight percent of tonal range with which to work. The technol- ogy does not restrict platemakers to one plate. In letters of recommendation reviewed by judges for FTA’s Technical Innovation Award, MacDermid’s customers attest to the benefits of LUX technology. 34 FLEXO June 2011 www.flexography.org
