Mimaki UJF-6042 Tabletop LED UV Printer
High-resolution A2-size tabletop LED-UV flatbed printer designed for direct-to-object printing on promotional products, industrial components, awards, signage, packaging, and specialty applications with media up to 5.9" thick.
Characteristics
The Mimaki UJF-6042 Tabletop LED UV Printer is a professional flatbed inkjet printing system engineered for high-quality direct-to-object production on a wide variety of rigid and specialty substrates.
Designed around a generous 24.0" x 16.5" maximum print area, the UJF-6042 provides approximately A2-size printing capacity while supporting materials up to 5.9" (150 mm) thick. This combination makes the printer suitable for producing customized promotional products, awards, plaques, signs, industrial components, gift merchandise, nameplates, packaging prototypes, and other value-added products.
The UJF-6042 is capable of resolutions up to an impressive 1,800 x 1,800 dpi. Mimaki's variable-dot technology can produce three different dot sizes, including a minimum drop size of approximately 4 picoliters, helping create smooth gradients, fine details, small text, photographic images, and precise graphics.
A precision ball-screw-type head conveyance mechanism improves ink-drop placement accuracy as the printhead travels across the media. Originally derived from Mimaki's higher-end printing technology, this system helps minimize banding while supporting accurate, high-resolution output.
The printer uses UV-curable ink and LED-UV curing technology, allowing the ink to cure during the printing process. This makes it possible to print directly onto a broad selection of compatible substrates, including plastics, glass, metals, and many other rigid materials.
Depending on the installed ink configuration, the UJF-6042 supports process colors along with specialty ink options such as white and clear. White ink can be used as an underbase when printing onto transparent or colored materials, while clear ink provides opportunities for decorative gloss and specialty effects.
Mimaki's MCT (Mimaki Circulation Technology) circulates white ink to help reduce pigment settling and maintain more consistent white-ink performance.
An integrated vacuum table uses air suction to hold compatible media securely in position during printing, helping maintain accurate placement and registration throughout production.
The UJF-6042 accommodates media weighing up to approximately 15.4 lb (7 kg) under standard conditions. When a height-adjustment table is used, the supported media weight is reduced to approximately 8.8 lb (4 kg).
With its combination of high-resolution printing, UV-LED curing, specialty ink capabilities, substantial media clearance, and compact flatbed configuration, the Mimaki UJF-6042 provides a versatile platform for customized product decoration and specialty industrial printing.
