Some call it magic. We call it superior UV technology. VersaUV LEF printers offer countless product customization and substrate possibilities, including printing directly on three-dimensional objects up to 3.94” thick.
LEF series of printers run at a cool, low-heat and use state-of-the-art UV-LED lamps. Combined with advanced ECO-UV inks, they offer the ability to print on virtually any material, including:
- PVC and plastics
- Leather and fabric
The LEF-20 fits on a studio, office, or workshop benchtop and is Roland DG’s most advanced compact flatbed option. It offers the following features that make it the most versatile of flatbed printers in its class:
ECO-UV ink is offered in CMYK, White and Clear, while ECO-UV S in CMYK and White. It instantly dries and produces wide color gamut results with sharp detail and rich color density. ECO-UV requires no degassing and stretches up to 220 percent around curves and irregular surfaces without cracking.
ECO-UV inks are extremely durable, giving indoor graphics scratch and chemical resistance, while outdoor graphics last up to six months and upward of two years when a Clear Coat ink layer is applied as a finish. ECO-UV ink is supplied in mess-free 220ml cartridges that are safe after curing.
Proper ventilation is required during Eco-UV production and an optional BOFA Air Filtration Unit that was created for use with Roland DG devices is available to virtually eliminate odor and to act as a stand and storage unit for jigs, fixtures and supplies.
The LEF Series of printers simply plug-in to a standard electrical outlet. Using a fraction of the power that other flatbed printers demand, an LEF offers significant savings on electrical costs per year.
The LEF Series uses LED lamps for UV-curing that last up to ten times longer than conventional UV lamps and can be instantly switched on or off, giving the user a true on-demand production without the typical warm-up time. In addition, the LEF automatically enters a low-power mode when it is not used for an extended period of time.
The LEF’s Roland Eco-label represents environmentally conscious printing. By providing a light source that is entirely ozone free and emitting light in the range known as Near-UV of the UV spectrum, it offers a safe alternative to conventional UV lamps.
The LEF Series utilizes an Automated Ink Circulation System to significantly reduce running costs and to help produce consistently brilliant image quality even on long print runs. With controlled ink circulation, the ink pigments are unable to settle in the ink lines, thus creating a smooth ink consistency and density that also lowers White and Clear ink waste.
The built-in laser alignment system sets the LEF up to print on different media. It represents the easiest and most effective way to uniformly print images on multiple substrate targets. Whether using it as a two-point reference to detect flat substrates or a center origin point of reference to print on curved or odd shaped items, the LEF’s laser alignment is and incredibly sophisticated and useful feature.
To ensure optimum print quality around the curvatures of objects, mist filters are incorporated in the LEF, catching the residual ink that mists when printing off the edge or curvature of a product. This cuts down on overspray and keeps the ink from settling on the printer’s internal components. Filters are designed to be easily replaceable by the end user.
Roland VersaWorks is user-friendly RIP software that helps users achieve outstanding print results. Using the latest Adobe® CSPI engine (3019), it offers a host of advanced features that include Predictive Ink Calculator, Spot Color Replacement, integrated Pantone® Spot Color Library and a Roland Texture Library with a library of ready-to-use Clear Coat finishes and other effects.
