Flatbed printing onto rigid and flexible substrates up to 15cm thick.
Based on the award-winning VersaUV technology, the VersaUV flatbed printer LEJ-640F prints CMYK plus white and clear inks onto both flexible materials and rigid substrates up to 15cm (6 inches) thick. With the LEJ-640F, you can print white on a variety of clear substrates for text and graphics that stand out. Layers of clear ink create custom patterns and embossing effects, perfect for premium brands. With a wide bed size of 1.6 by 2.5m, the LEJ-640F lets you explore a wide range of applications with just one device, from packaging prototypes and POP to wide-format signage and window displays.
Speciality inks add value and enhance your creativity
The LEJ-640F outperforms traditional CMYK printers with the addition of white and clear inks that together open up a new world of design opportunities. With high-opacity white ink, you can print crisp, bright text and graphics on a range of coloured and transparent material. Clear ink can be layered into striking gloss and matte finishes. More than 70 ready-to-apply patterns are included in Roland’s VersaWorks Texture System Library.
Large UV-LED lamps increase productivity while lowering costs
The LEJ-640F features the latest generation UV-LED lamps, designed to cure Roland ECO-UV inks. This state-of-the-art curing system is safe to use and requires little power to operate. Lamps last up to 10,000 hours. The LEJ-640F LED curing lamps automatically reposition themselves for optimum image quality in each print mode.
With a printing area of 1600 x 2500mm, the LEJ-640F lets you explore a whole range of applications including indoor and outdoor wide-format signage, retail POP and POS displays, packaging prototypes, exhibition panels, free standing display units (FSDUs) and banners, window, floor and wall graphics, and will accept industry standard sheet sizes.
The LEJ-640F can print on a wide range of materials; rigid, flexible and sheets. These include polyurethane, polystyrene, polypropylene, cardboard, aluminium panels, fluted and corrugated boards and acrylics. It’s also possible to print on sheets of flexible material such as self adhesive vinyl, polycarbonate, PET, polyethylene and PVC banner. The versatility and ease of use allows the operator to deliver many types of applications from one device.
A fully-automated, built-in sensor determines the relevant print head height for each job, allowing for the thickness of the media to be printed. This feature prevents head strikes and ensures reliable, high-quality printing up to 1440 x 1440 dpi across the widest range of substrates with weights up to 200Kgs. The bed can be divided up into seven areas for ease of material handling and maximum productivity. Roland’s unique ink circulation system prevents white ink particles from settling for reduced waste and consistent print quality.
