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.

ECO-UV Ink

ECO-UV inks adhere to a wide range of treated and untreated substrates with exceptional color gamut. Instant-drying and flexible, ECO-UV inks produce prints that require no degassing and can be stretched and applied around curved surfaces and edges without cracking.

The LEJ series supports ECO-UV inks in two formulations: original ECO-UV in CMYK, white and clear and ECO-UV S ink in CMYK and white.

Original ECO-UV delivers outstanding performance for printing environments that require clear coat to finish graphics.  For wide-format VersaUV devices configured with CMYK and white only (CMYK + White + White), users can upgrade to ECO-UV S for added flexibility.  ECO-UV S expands up to 220 percent, allowing graphics to wrap uneven shapes, indentations, corners and curved surfaces.  With ECO-UV S, prints mold perfectly to the contours of PET bottles and plastic cups, and adhere flawlessly to vacuum-formed plastic that is commonly used for items ranging from food service trays to auto parts packaging and consumer electronics cases.

Choose from four ink configurations:
  • Original ECO-UV
    • CMYK + White + Clear
    • CMYK + White + White
    • CMYK + Clear + Clear
  • ECO-UV S
    • CMYK + White + White

As the most versatile ink configuration, CMYK + White + Clear can be used for a wide range of applications including packaging prototypes, labels, high end press-proofs and unique textured graphics.  (ECO-UV only)

The CMYK + White + White mode achieves higher opacity without slowing down the printing with overprinting. It’s perfect for white text and graphics, undercoats and to enhance the brightness of four-color prints. The white produced with this ink configuration can be up to 1.5 times more opaque than the normal white, all without requiring a complicated workflow or overprinting. Choose from ECO-UV or ECO-UV S formulations.

ECO-UV Clear adds remarkably rich special effects ranging from matte and high-gloss finishes for area highlights or floods to custom-textured effects such as faux leather, crocodile skin and even Braille. The CMYK + Clear + Clear mode can build up three-dimensional textures twice as fast as the normal ink mode and can produce more dramatic effects with bigger reliefs.  (ECO-UV only)

ECO-UV inks are packaged in no-mess 220ml cartridges and safe after curing. Proper ventilation is required. The LEJ series is ventilation-ready, featuring a ventilation hood for easy connection with an air filtration system.

* Room ventilation and a Roland approved air filtration system are required. Please consult the MSDS for more guidance on the proper use and ventilation of ECO-UV or ECO-UV S inks.

Unsurpassed Media Compatibility

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 customize 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 Foam-Cor® or Gatorfoam® for POP and exhibit walls.

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. 

Production Print Speeds

The LEJ-640 features large UV-LED lamps to expedite production with a maximum print speed of 133 sqft./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.

Curing SystemState of the Art Curing System for Matte and Gloss Finishes

The VersaUV's ability to reposition its twin UV-LED lamps automatically increases productivity in high quality modes and allows simulation of matte and gloss varnishing effects.

Innovative Automated Ink Circulation System

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.

Longer Life

VersaUV LED lamps last up to 10,000 hours, ten times longer than conventional UV lamps.

Low Heat

While conventional UV lamps can reach temperatures as high as 1500°F (800°C) requiring complex heat management systems, the LED lamps on the LEJ-640 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.

VersaWorks RIP Software

VersaWorks RIP software has been developed exclusively for Roland inkjet printers and printer/cutters. This true Adobe PostScript 3 RIP ensures exceptional production output with unmatched ease of use and incorporates the latest Adobe CPSI 3019 engine.

VersaWorks supports the Roland Color system which accurately reproduces more than 1,000 spot colors from color charts and swatch books. For the VersaUV series, VersaWorks also includes the Roland Texture Library featuring 72 ready-to-use textures that can be applied to designs by layering the LEJ’s clear coat ink. For white ink applications, you can select from either single pass or dual pass modes.

With VersaWorks, you can choose from print options including a high-speed mode for production banner printing, the MAX Impact preset for vivid outdoor graphics and Artistic mode for exceptional indoor graphics. In addition, VersaWorks features Variable Data Printing and supports up to four Roland devices simultaneously including printers, printer/cutters and cutters. It automatically estimates the ink usage and print time for each graphic so you can accurately monitor time and costs.

VersaWorks features include embedded ICC profile support, ink level adjustment tools, soft proofing capabilities, error diffusion for outstanding print quality and advanced cropping, tiling and nesting options. Support for Roland cutters allows you to pair the LEJ with a Roland cutter to cut flexible media in a seamless workflow. VersaWorks is fully compatible with Windows 7, Vista, XP and 2000.
