LEF-12

The LEF delivers Roland's unparalleled UV printing capabilities, facilitating
direct printing on a vast array of VersaUVsubstrates and even three-dimensional items, including giftware, awards, packaging, prototypes, and promotional and industrial products.

One of the most advanced and affordable benchtop UV printers in its class, the LEF-12 has a maximum print area of 12 inches by 11 inches, and can handle solid objects up to 3.94 inches thick. You can even add stunning graphics for high visual impact and unique dimensional effects, whether printing logos or any type of artwork on a vast array of items, including thumb drives, pens, cell phone covers, laptops and more. You're only limited by your imagination.

White ink can be added as a spot colour, or a flood behind CMYK to make colours pop on dark backgrounds or clear materials such as acrylic. With the addition of Clear Coat ink, gloss or matte finishes can be produced for enhanced visual and tactile effects.

Direct Printing on 3D Objects

The LEF-12 is capable of printing anything on both flat and uneven surfaces for 3D objects up to 100 mm (3.94” ) thick. Because the integrated UV-LED lamp instantly cure ink during printing, it can print directly onto materials such as PET, ABS, PVC, polycarbonate, PS and other plastics, as well as papers and card stocks.

The LEF-12 Supports two print modes.
Standard mode Ideal for printing fine detail on flat surfaces.
Distance mode More suitable to print on objects where the surface is not level.

Clear Ink Enhances the Print Quality and Appearance

The inclusion of Roland’s clear varnish enables users to produce unusual and creative textures on all materials. Among the advantages offered by the LEF-12 are high-grade gloss and matte finishes as well as 3D “impasto” effects that can be created by stacking many layers of clear ink. The LEF-12 offers 72 ready-to-use texture patterns, all of which are easy to incorporate into a design. With just one click you can create high-value exquisite, appealing and unique effects for your customers.

High-density Opaque White Ink

The LEF-12 is compatible with Eco-UV high-density white ink in addition to full four-colour CMYK inks and clear varnish. The versatility of white ink delivers innovative text, logos and images onto coloured backgrounds. Use white ink as a base coat to add vivid colour printing on transparent PET base materials, or as a primer on darker materials. Being an inkjet printer, the LEF-12 dispenses with the time-consuming conventional plate-making process. This means it can deliver small batch jobs or just one item without a lengthy set-up process.

Performance

Convenient Height Adjustor

With 3D items placed on the flat table, once the automatic height adjusting function has been selected, the LEF-12 starts to adjust the position by moving the flat table back and forth until its surface reaches the height most suitable for operation. This function also helps to maintain the production of quality prints due to automatic adjustment of the distance between the print-head and the material surface.

The Sealed Cover Construction Protects the Material against Admission of Dust During Printing

The LEF-12 includes a safety hood to protect the operator from UV light during operation and a screen to prevent dust falling on the surface of materials whilst printing. Equipped with long-life LED UV-curing lamp, the LEF-12 requires no warm-up time, making it efficient to use and cool to touch. This LED curing technology means it can be used in conjunction with delicate materials which, traditionally, have been difficult to dry efficiently.

Ink Mist Absorbing Function

The LEF-12 features an ink mist adsorbing system by which air-borne ink mist inside the printer is collected for removal. The system works by employing two fans installed around the print-head and flat table, that blow any ink mist into an adsorbing filter. This system is valuable to maintain consistent printing operation.

Compact Construction and Low Energy Requirement

The desk-top construction of the unit allows it to be installed in restricted spaces in the workplace. The LEF-12 operate on standard household power supplies, and do not require special electrical installations.

Unmatched Print Quality with “Roland Intelligent Pass Control”

Across a wide variety of applications and media, Roland Intelligent Pass Control technology delivers outstanding image quality in all print modes while eliminating virtually any signs of banding. This patent-pending system ensures that graphics look great when viewed indoors or outdoors, up close and at a distance.

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.

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 LEF-12 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.

Optional deodorising system

An Optional Deodorizing Unit to Create a Comfortable Work Environment

An optional deodorizing unit is available for the LEF-12. It contains an activated carbon filter which effectively removes the odor and volatile substances that occur during printing. This unit can be installed easily underneath the LEF-12.
