Based on award-winning VersaUV technology, the VersaUV hybrid LEJ-640 prints CMYK plus white and clear inks on both roll media and rigid substrates up to 13mm (.51â€) thick. With the LEJ-640, you can print white on a variety of clear media for text and graphics that stand out. Layers of clear ink create custom patterns and embossing effects, perfect for premium brands. At 64â€ wide, the LEJ-640 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-640 outperforms traditional CMYK printers with the addition of white and clear inks that together open up a new world of design options. With high-opacity white ink, you can print crisp, bright text and graphics on a range of colored and transparent media. Clear ink can be layered into striking gloss and matte finishes. More than 70 ready-to-apply patterns are included in the VersaWorks Roland Texture System Library.
Supports both flexible roll media and rigid substrates up to 13 mm thick
With the LEJ-640, you can print on virtually any substrate, from thin flexible films to lightweight board and cardboard up to 13mm (0.51â€) thick, without distortion to the substrateâ€™s shape or surface finish. A media securing mechanism ensures high-quality printing by holding flat substrates in place and controlling warp.
For unattended production, the LEJ-640 features a built-in take up system supporting a wide variety of roll media.
Large UV-LED lamps increase productivity while lowering costs
The LEJ-640 features the newest 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-640 LED curing lamps automatically reposition themselves for optimum image quality in each print mode.
A fully-automated, built-in sensor determines the proper print head height for each LEJ-640 job, accounting 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. Rolandâ€™s unique ink circulation system prevents white ink particles from settling for reduced waste and consistent print quality.
