Based on award-winning VersaUV technology, the 64" LEJ-640 prints CMYK, white and clear coat on virtually any substrate up to a half-inch thick. With the LEJ-640, you can print white on a variety of clear and colored media for text and graphics that stand out.

Layers of clear coat finish your graphics with custom patterns and embossing effects, perfect for premium brands. As a hybrid printer, the LEJ-640 accepts both roll and flat media substrates from films to Gatorfoam®. Now with just one device, you can explore a world of applications, from packaging prototypes and POP to wide-format signage, décor, exhibits and window displays.

VersaUV supports printing on BOPP, PE, PET film, offset printing stock and more. The low heat UV LED lamps allow printing on heat-sensitive media such as shrink wrap, pressure sensitive media and paper stocks with no risk of damaging the substrate. You can also use the VersaUV to create original patterns and 3D domed corporate logos directly onto synthetic and natural leathers and to customise window coverings, tapestries and other interior décor items. The LEJ-640 enables printing on rigid media such as corrugated cardboard for folding cartons, polycarbonate sheets for membrane switch applications and Foamcore or Gatorfoam® for POP and exhibit walls.

The LEJ-640 features large UV-LED lamps to expedite production with a maximum print speed of 12.4 sqmt./hr. in High Speed mode. The 1440x1440 dpi mode produces press-proofs with flawlessly smooth gradations, super fine details and sharp text on actual substrates used for production. Roland Intelligent Pass Control™ ensures consistent print quality with virtually no signs of banding in all print modes.

The automated Ink Circulation System circulates the white ink in the LEJ-640 every eight hours to prevent the settling of pigments in the lines. In addition, this system controls the discharge of white ink and minimizes waste by monitoring the white ink usage and the types of jobs that are printed.

By preventing unnecessary discharges and minimizing the amount of ink that is subject to settling, this automated system significantly reduces the ink waste and eliminates manual maintenance procedures that add labor and decrease productivity.

Note that, due to the nature of white ink, the white ink cartridge still needs to be shaken prior to use each day as the ink in the cartridge is not circulated by this system.

Automated Print Head Management - A built-in sensor checks for proper media thickness preventing head strikes and ensures highly reliable, 1440x1440 dpi printing on the widest range of substrates.

Long Life LED UV Lamps - VersaUV LED lamps last up to 10,000 hours which is ten times longer than conventional UV lamps.

Low Heat - While conventional UV lamps can reach temperatures as high as 800°C (1500°F) requiring complex heat management systems, the LED lamps on the VersaUV series generate very little heat. This ensures that the UV lamps virtually eliminate any heat-related risks such as substrate damage and head crash caused by media deformation.

Instant On/Off - LED lamps can be turned on and off instantly and are ready to use immediately after the printer is turned on. By contrast, conventional curing systems may take up to ten minutes to reach the targeted output level. Conventional curing systems also require complex, noisy and failure-prone shutter systems to protect substrates and head capping systems from exposure to UV light and heat.

The staggered arrangement of UV lamps, with the left lamp mounted in line with the print heads and the right lamp mounted forward, is another Roland innovation.

This first-of-its-kind configuration enables a choice of gloss or matte Clear finishes. When gloss finish is selected, only the right lamp is used for curing, allowing enough time for Clear droplets to spread and form a smooth surface which reflects light evenly. For matte finish, both lamps are used, curing the Clear droplets shortly after they land on the media to form a rough surface which scatters the light.

There's no question that Roland inkjets combine unbeatable performance with legendary Roland reliability. As further proof of their unmatched reliability, Roland is pleased to offer an unprecedented Three-Year Heads and all Warranty on the VresaUV LEJ-640. All that's required for this bonus is return of the registration card with installation information within 30 days of your purchase and confirmation* that Roland inks are running in the machine.
