Upgraded WebFed Screen Press UV-LED curing technology is the latest upgrade to the K61 from Kammann (www. kammann.com). The K61 ECO UV-LED is a roll-to-roll, web screen-printing system that features a complete servomotor drive system and modular design that allows combinations of screen printing, die cutting, laminating, stamping, and finishing. According to Kammann, UV-LED curing uses an average of 8 w/lamp for web systems, eliminates noise pollution from exhaust blowers, emits low amounts of heat, has a compact footprint, and supports more than 10,000 hours of manufacturing use. Other system upgrades include digital web- and tension-control features designed to allow the machine to print color-to-color registration in the range of ± 50 µm based on material thickness and ink viscosities.
Semi-Rigid Polycarbonate
Software RIP
Gerber Scientific Products (www.gspinc.com) recently introduced LexEdge II 5-mil a semi-rigid Lexan material that has a customformulated print surface designed specifically for use with Gerber Edge series printers. According to Gerber, LexEdge II 5-mil is ideally suited for the production of dynamic, sub-surface graphics such as membrane switches, keyboard overlays, architectural signs, instrument panels, and exhibit/display work. Gerber also says it is dimensionally stable and resists tearing, abrasion, and heat—and is an excellent material option for producing small decals with a low profile for thinner, smooth-touch label applications. LexEdge II 5-mil is 15 in. (381 mm) wide and available in lengths of 10 and 50 yd (9.2 and 45.8 m).
Screen USA (www.screenusa.com) has added features to the newest version of the HQ-510 RIP designed to increase prepress productivity and drive more Screen brand output devices. The PostScript-language-compatible RIP is based on Harlequin technology, and Screen says HQ-510 RIP v8.3 incorporates all the advances of PostScript 3 and PDF, supports the company’s recently launched PlateRite HD 8900 series thermal platesetter, and is compatible with Windows 2003 Server, Windows 2008 Server 32-bit, Windows 7 32-bit, and Windows XP with Service Pack 2. The RIP engine processes native PostScript, PDF, and XPS files. Version 8.3 accepts PDF/X-4, PDF 1.7, and HD Photo file types. The RIP’s PDF retained-raster feature is designed to accelerate the processing of variable printing jobs, even if they are delivered as basic PDF files. Shared image data are identified and rendered only once, then returned to the RIP process and merged with variable content when required. Optional tools include specialized color management, screening, trapping, TIFF/IT-P1 input, postRIP imposition, and in-RIP OPI.

Fluorosilicone Gel NuSil Technology’s (www.nusil.com) new FS-3502-1 is a 100 mol%, two-part, white, fluorosilicone gel available in a 1:1 mix ratio. The gel is designed to fill small gaps and backfill electronics in applications that require solvent and/or fuel resistance, and it’s formulated to bond aggressively with most surfaces. According to NuSil, the gel’s cure can be heataccelerated and notes that FS-3502-1 is hydrocarbon-resistant for components exposed to aviation fuels, such as JP-8; chemicals; and solvents used in automotive, electronics, and aircraft applications. According to NuSil, a low Type 00 durometer allows the gel to exhibit low modulus and absorb stresses incurred during thermal cycling. FS-3502-1 is controlled in accordance with applicable ITAR regulations and is RoHS compliant. The gel comes standard in white. Translucent or color-matched gels can be produced.
