VersaUV LEJ-640F

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.

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.

Versatility

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.

Three ink configurations

Roland DG allows you to choose the ink configuration that best suits your business. The standard CMYK+White+Clear ink configuration can be used for the largest range of applications. The CMYK+White+White configuration is ideal for opaque white printing on transparent and dark-coloured substrates. The (CMYK+Gloss+Gloss) configuration is ideal for doming or embossing effects. In the last mentioned ink combination, you can apply the clear ink faster than in the standard configuration.

ECO-UV ink

The ECO-UV ink ensures high density printing in a wide range of colours. The ink cures instantly and its flexibility prevents it from breaking up when the material is bent or stretched. ECO-UV is available in CMYK+White+Gloss in 220 ml cartridges. Roland DG recommends the use of extractors with these inks.
