EFI’s 3.2-meter UV roll-to-roll Vutek QS3250r is capable of handling media up to 126.5-inches wide and 0.125-inches thick. An 8-color (CMYKcmyk) machine that is switchable to 4-color (“Fast-4”) for optimized production, it offers up to 1080-dpi resolution and a top speed of 1850 sq ft/hour. Suggested applications include P-O-P displays, indoor and outdoor posters and signage, fleet graphics, and high-end wallpapers.

The machine features a platen control unit to accommodate printing on low-cost and heat-sensitive materials; a temperature-control unit to eliminate stress on media and ensure smooth travel; a media-alignment scale; a platen vacuum gauge; interior lights for immediate viewing of output; multiple-roll capability (two 60-inch rolls); and more. Options include an automated laser system that allows for precise double-sided printing, as well as a heavy-duty unwinder. The QS3250r has been optimized for EFI’s Fiery XF RIP, which is optional.

EFI also features two entry-level production wide-format UV printers with the Rastek badge: the Rastek H652 UV hybrid and the Rastek T1000 UV flatbed. Both printers feature grayscale printheads and are aimed at production print shop environments “where fast service, superior image quality, and printing on the widest range of substrates are the keys to customer satisfaction and increasing profits,” says EFI.
The Rastek H652 (CMYK+W) builds on the success of the Rastek H650, adding nearly twice the speed: It can reach speeds of up to 455 sq ft/hr in Express mode (2-pass, 300 dpi) and 255 sq ft/hr in Quality mode (4-pass, 600 dpi); top resolution is 1200 dpi. The H652 can handle rigid and flexible media up to 1.8-in. thick and 64-in. wide.

The Rastek T1000 flatbed (CMYK+W) has a three-zone 52 x 98-in. vacuum table and can accommodate media up two-inches thick, including difficult-to-handle substrates that require superior hold-down. It boasts speeds up to 460 sq ft/hr in Express mode (2-pass, 600 x 300 dpi) and 317 sq ft/hr in Quality mode (4-pass, 600 dpi); top resolution is 1200 dpi.

Other EFI UV machines include the Vutek GS series (GS5000r, GS3200, and GS2000); the rest of the Vutek QS series (Vutek QS3220, QS2000, and QS220); and the Rastek H650 and Rastek T660 printers.
