Mimaki, a major manufacturer of wide-format inkjet printers and cutting plotters, showcased the new flatbed UV inkjet printer ―UJF-7151 plus‖ at the International Graphic Arts Show 2015 in Tokyo, Japan on September 11. The market launch will commence in November, 2015. Mimaki says the UJF-7151 plus delivers high quality printing while ensuring accurate ink droplet placement with the maximum printable size of 710 × 510 mm (28 × 20in). From the beginning,
Mimaki has been very active in developing inkjet printers. In comparison to conventional analog printing, recently, there has been a growing demand for digital, on-demand, and plate-less inkjet printing because of its ability to quickly provide high-mix and low-volume printing. The UJF-7151 plus is an on-demand printing solution for the screen printing industry. According to Mimaki accurate ink droplet placement is crucial for delivering high-quality printing. Thus, while ensuring accurate ink droplet placement, the UJF-7151 plus delivers high-quality printing.
The UJF-7151 is capable of printing onto Kiku-han size which is often used at screen print factories in Japan. Based on the information provided by Mimaki the UJF-7151 plus improves accuracy by modifying the mechanical structure of the print table and offers high-performance printing that meets the position accuracy necessary for additional printing on preprinted surfaces. Fine lines, edges, and small texts are clearly represented. In addition, double-layer printing, color printing on a white base layer is possible. The patented MFD1 dithering technology processes image data along with retaining the original image quality. The highly improved quality-control MAPS4 reduces banding and uneven color printing, achieving top-level productivity within the same product range at a maximum printing speed of 3.3 m2/h.
The new printhead comprises a continuous ink circulation system to help prevent ink sedimentation and clogged nozzles. When nozzles are clogged, the nozzle check unit (NCU) automatically detects and cleans the clogged nozzles. Furthermore, the UJF-7151 flatbed UV printer employs a nozzle recovery system (NRS), ensuring that only good nozzles are used as substitutes if clogged nozzles are not recovered after cleaning. These functions maintain constant printing and reduce waste printing due to defective nozzles.
