Supports Both Flexible Roll Media and Rigid Substrates up to 13mm (0.51”) Thick

With the LEJ-640, you can print on virtually any substrate, from thin flexible films to lightweight board and cardboard up to 13mm(0.51”) 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 LEJ-640 features a built-in take up system supporting a wide variety of roll media.

Reproduces Smooth Gradations in Highlights and Shadows

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 × 1440 dpi across the widest range of substrates. Print quality is further enhanced by Roland Intelligent Pass Control® technology which delivers smooth gradations and flawless solid fills with virtually no banding in every print mode.

Add Unique Special Effects – All on One Device

The VersaUV beautifully prints your design and finishes graphics with rich special effects created by 3-dimensional layers of clear coat ink. 72 ready-to-use textures are available, adding luxury and distinction to your prototypes and comps. Choose any combination of matte and gloss finishes and layer them for interesting patterns. Use white ink to print on transparent and shrink wrap film for food packaging prototypes.

The ECO-UV Ink with Three Ink Configurations

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 with matte or gloss varnish and unique textured graphics.
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 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.

The ECO-UV S Ink Opens Up New Opportunities for On-Demand UV Printing

ECO-UV S Ink stretches and perfectly conforms to curved or uneven surface. ECO-UV S Ink is an ideal solution for industrial prototyping of vacuum-formed and molding products and small lot production of signage or POP displays.

Performance

Larger UV-LED Lamps Increase Productivity While Lowering Costs

The LEJ-640 features the newest generation UV-LED lamps, designed to cure Roland UV inks. This state-of-the-art curing systems 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.

Automated Ink Circulation System for Consistent Long-Term Image Quality

The VersaUV series comes with Roland’s unique, automated ink circulation system that prevents the pigment in white ink from settling. This system automatically reduces waste of white ink, lowers running costs, produces exceptional image quality, and ensures consistent white density throughout the longest production runs.

Software

VersaWorks RIP Software

The Roland’s true Adobe® PostScript® 3™ RIP is easy to use and incorporates the latest CPSI engine for exceptional production output. Features include estimation of ink usage and print time for each job, control of up to four Roland devices, and accurate color matching using the Roland Color System Library.

Roland OnSupport Messaging System Included for Remote Production Management

The LEJ-640 features Roland OnSupport, an online customer support system allowing users to remotely track the status of the printer’s activities. The system sends e-mails to users notifying them of important information such as when a job is completed and when ink is running low. With Roland OnSupport, users can also quickly download firmware updates and important product information by accessing an exclusive website with just one mouse click.
