UV Printer Roland VersaUV LEJ-640F serija

Flatbed printing onto substrates up to 15cm thick

The VersaUV LEJ-640F prints CMYK, white and clear inks onto both flexible and rigid substrates up to 15cm thick. You can print white on a variety of clear or dark substrates for text and graphics that stand out. Use the transparent ink to create textures and embossing effects. With a wide bed size of 1.6m by up to 3.3m, the LEJ-640F lets you explore a broad range of applications, including packaging prototypes, signage and displays.

Specialty inks add value and enhance your creativity

The LEJ-640F outperforms traditional CMYK printers with the addition of white and transparent inks. With the high-opacity white ink, you can print crisp, bright text and graphics on a range of coloured and transparent substrates. The transparent (clear) ink can be layered to create textures and embossing effects. You can also use it for striking gloss and matte finishes.


The LEJ-640F can print on a wide range of materials: rigid, flexible and sheets. These include polyurethane, polystyrene, polypropylene, cardboard, aluminium panels, fluted and corrugated boards and acrylics. You can also print on sheets of flexible material such as self-adhesive vinyl, polycarbonate, PET, polyethylene and PVC banner.

Advanced technology

A fully-automated, built-in sensor determines the relevant print head height for each job. This feature prevents head strikes and ensures reliable, high-quality printing up to 1440 x 1440 dpi on substrates weighing up to 200kg.

Large UV-LED lamps increase productivity while lowering costs

The LEJ-640F features the latest 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. The lamps last up to 10,000 hours. The lamps automatically reposition themselves for optimum image quality in each print mode. *The life span of Roland UV-LED lamps may vary due to temperature and printing conditions.
