Printing on 3D objects paves the way for limitless applications in your business

Advanced LEF-20 Benchtop UV Flatbed Printer Features

The larger LEF-20 builds on Roland’s advanced UV-LED direct printing technology with a host of features that make it the most advanced and versatile printer in its class.

  • In addition to a faster UV-LED curing system, the LEF-20 features a distance print mode for outstanding print quality on curved objects. Up to 20 job presets are included as well, allowing you to recall specific media settings instantly for your most popular applications.
  • New height sensor bar made with non-magnetic material allows printing on magnetic items such as iPad covers.
  • The LEF-20 includes new, advanced UV-LED curing system to expedite production with two timesfaster clear ink and CMYK ink printing.

Laser Alignment System

Another Roland innovation is the built-in laser alignment system for the VersaUV LEF-12. With the laser alignment system, you can quickly and easily setup for different materials. To ensure proper image placement, there are two methods for setting the laser’s point of origin, including:

  • Two-point reference – This method uses the lower right and upper left corner of the object as a reference point to generate a bounding box that can be read by Roland’s VersaWorks, to ensure proper image placement for printing on a variety of standard sized objects.
  • Center origin – Typically used for circular, curved or odd shaped items, this method requires the user to manually input the dimensions of the printable item into VersaWorks to set the reference point for the laser and ensure proper image placement.

Mist Filters

To ensure outstanding print quality around the curvatures of objects, two mist filters are incorporated in the LEF-12, one on the back of the unit and the other located between the print head and the UV lamp. These mist filters catch all residual ink that may mist when printing off the edge or curvature of a product. This cuts down on overspray and keeps the ink from settling on the printers internal components. Both filters are replaceable by the end user.

Advanced ECO-UV Inks

LEF printers come configured with CMYK, white and clear ECO-UV inks. ECO-UV ink was specially formulated for the VersaUV family of printers and printer/cutters to deliver high color density and wide gamut for applications ranging from promotional and industrial products, giftware and awards to signage, packaging, POP and small displays. Clear ECO-UV ink produces matte or gloss finishes and improves scratch and chemical resistance for extended durability – up to two years outdoors. Layers of clear ink can also be applied to create 3D textures and embossed effects.

* 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.

Optional Air Filtration Unit

Custom built for the LEF series, an optional air filtration system is available from Roland. While ensuring proper ventilation, this unit also doubles as a stand and storage unit for jigs, fixtures and supplies. When connected to the stand, the Roland air filtration system virtually eliminates odor. The VersaUV LEF is ventilation-ready, featuring a built-in connector for the Roland unit or other standard air filtration systems.

Designed for the Environment and Safety

The energy-efficient VersaUV series uses only a fraction of the power used by a conventional UV printer and automatically enters a low-power mode when it is not used for an extended period of time. This energy-efficient design literally saves thousands of dollars in electric bills each year and reduces considerably the emission of greenhouse gases. And because LED lamps do not require any warm up time, they save both time and energy.
Traditional UV curing equipment can expose operators to harmful ozone and UV-B and UV-C radiation. Ozone is a known air pollutant that can cause lung damage and respiratory problems. UV-B and UV-C radiation can cause eye damage, skin cancer and accelerated skin aging. The LED lamps on the VersaUV LEF are completely ozone-free and only emit the much safer UV-A radiation.

Prints Directly on Three-Dimensional Objects

The VersaUV LEF-20 has a maximum print area of 20” x 13” x 3.94,” and the LEF-12 prints on objects up to 12” x 11” x 3.94” in size.
The ingenious combination of advanced ECO-UV inks with the LEF’s low heat state-of-the-art UV LED lamps enables printing on a wide range of treated and untreated substrates, including PVC, PET, ABS, wood, boards, acrylic and much more. You can even print directly on metallic electronic devices or heat sensitive plastics without the risk of damage.

Roland Intelligent Pass Control™

Roland Intelligent Pass Control technology, developed by Roland software engineers, represents the pinnacle of inkjet printing. This patent-pending system precisely controls dot placement between passes and delivers unprecedented imaging performance in all resolutions. Roland Intelligent Pass Control enables the VersaUV LEF-12 to produce exceptionally smooth gradations and solid colors with virtually no banding in all print modes.
