Based on award-winning VersaUV technology, the 64″ LEJ-640 hybrid UV flatbed printer produces 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 coloured 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 large format 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.
Across an unprecedented range of substrates, the LEJ-640 prints ECO-UV inks in CMYK + White + Clear. The LEJ-640 can be configured with any of these three ink combinations:
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.
The CMYK + White + White mode achieves higher opacity without slowing down the printing with overprinting, perfect for white text and graphics, undercoats and to enhance the brightness of four-colour 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.
ECO-UV Clear adds remarkably rich special effects ranging from high-gloss finishes for area highlights 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 ink shines for indoor graphics, offering superior scratch and chemical resistance. Outdoors, ECO-UV ink lasts up to two years when Clear is applied as a finish and up to six months without Clear. ECO-UV ink is packaged in no-mess 220ml cartridges and safe after curing. With ECO-UV ink, proper ventilation is recommended. The LEJ-640 series is ventilation-ready, featuring a connector on the back of the printer for easy connection with an air filtration system.
ECO-UV ink adheres to a wide range of treated and untreated substrates with exceptional colour gamut. Instant-drying and flexible, ECO-UV ink produces prints that can be stretched and applied around curved surfaces and edges without cracking.
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.
An optional extraction unit is available for the VersaUV series models. It contains an activated carbon filter which effectively removes the odor and volatile substances that occur during printing. It is effective in making your work environment comfortable when the VersaUV is operating.
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, 1440×1440 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.
VersaWorks RIP software has been developed exclusively for Roland inkjet printers and printer/cutters. This RIP ensures exceptional production output with unmatched ease of use.
VersaWorks supports the Roland Color system which accurately reproduces more than 1,000 spot colours from colour charts and swatch books. For the VersaUV VersaUV series, VersaWorks also includes the Roland Texture Library featuring 70 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. 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, software proofing capabilities, error diffusion for outstanding print quality and advanced cropping, tiling and nesting options. Support for Roland cutters allows you to pair a Roland cutter with any wide-format or desktop printer for print/cut applications. The PerfCut function produces precision perforated cut lines. VersaWorks 4.0 is fully compatible with Windows 7, Vista, XP and 2000.
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 VersaUV 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.
