Specialty inks add value and enhance your creativity
The Roland LEJ-640 flatbed printer 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 13mm (0.51”) thick
With the Roland LEJ-640 flatbed, you can print on virtually any substrate, from thin flexible films to lightweight board and cardboard up to 13mm (0.51”) thick, without distortion to the substrate’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 Roland LEJ-640 flatbed features a built-in take up system supporting a wide variety of roll media.
Large UV-LED lamps increase productivity while lowering costs
The Roland LEJ-640 flatbed 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 Roland LEJ-640 flatbed 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 Roland LEJ-640 flatbed 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. Roland’s unique ink circulation system prevents white ink particles from settling for reduced waste and consistent print quality.
