FLEXO Magazine : November 2010
HD FLEXO www.esko.com firstname.lastname@example.org Visit us at: LabelExpo Americas 2010 14-16 September - Chicago Stand: 5202 The new quality benchmark in flexo printing HD Flexo combines high resolution imaging with advanced screening. The result is a digital flexo plate for superb printingquality and stability. Finally, flexo is able to match offset printing. Benefits at a glance... • Outstanding tonal range, detail & contrast • Smooth vignettes & gradients - print to zero • Reduction of image correction & retouching • Simplified conversion from Offset & Gravure HD Flexo is one of EskoArtwork’s many new technological innovations. Discover today how EskoArtwork can boost your flexo print quality. HD-Flexo A4- Americas.indd 1 7/16/2010 11:49:42 AM Flint Group’s New Exposure Technology - nyloflex® NExT A New Innovative Approach To Achieve Flat-Top Dots By Rich Emmerling Flint Group’s nyloflex® NExT high output UV technology is able to generate unique element shapes with precisely repro- duced surfaces, commonly known as flat-top dots, providing all the benefits linked to this structure: increased tonal range along with optimizing surface textures to greatly improve ink lay down as well as to increase solid ink density. However, compared to competitive systems, the main advantage of the new UV exposure technology is that it does not involve the use of inert gases with all its risks and does not require expen- sive consumables. Furthermore there are no processing steps added to the standard digital plate workflow, such as film or negative film lamination. As with other new technologies addi- tional equipment installation or retrofitting of existing exposure units will be necessary. The nyloflex® NExT process can easily be integrated in the existing workflow of digital plates. Background The main contributor to the change in the finished plate image structure with digital plates, as compared to conven- tional analogue plates, is that digital plates are exposed in the presence of oxygen. Oxygen is an inhibitor of radical polymer- ization and therefore reduces the dimensions of positive relief elements and an opening of reverse relief elements. In respect to tonal areas, file adjustments are required to the highlight portion of the tonal scale. This process is known as a bump-up curve creating a reduction on the gamut from mask to plate. All the processes currently being used today to produce a plate with the flat-top dots profile are designed to either elimi- nate oxygen or to greatly reduce the effect of oxygen to the plate surface.
