Mimaki UJF-7151 Plus

The UJF-7151 plus improves accuracy by modifying the mechanical structure of the print table to offer high-performance printing. This accuracy is required if overprinting on preprinted surfaces is needed to ensure that fine lines, edges, and small letters or text elements are cleanly reproduced, this also makes color printing on a white base layer possible.

The patented MFD1 dithering technology processes image data so that the original image quality is retained. A significant improvement in quality-control using MAPS4 reduces banding and uneven color printing at a maximum printing speed of 3.3 m²/hr. By reaching approximately twice the speed of previous models, the UJF-7151 achieves approximately 2.6 times the productivity of competing printers in its class

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. The UJF-7151 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.

The mechanical structure of the unit is configured for high-precision printing which, unlike conventional models, has a print tablet hat moves during the print cycle for reducing printer vibration. Two balls crews installed on both sides of the table facilitate this movement.

Mechanical structure achieves high-precision printing


To improve precision, modifications applied are as follows.
To reduce printer unit vibration, the print table moves during printing instead of the Y-bar. Two ball screws are installed on both sides of the table to assist with its movement. In addition, four motor-driven legs are added beneath the table to maintain horizontality when the table is lifted or lowered.

Mimaki Advanced pass System 4 (MAPS4)


Generally, swath boundaries are straight lines. Therefore, a slight misalignment between boundaries causes banding or uneven color printing. MAPS4 reduces banding and uneven color printing with blurred boundaries similar to gradation printing.

Banding and uneven color printing are reduced by scattering swath boundaries. Beautiful print image is obtained.











Bandings appear on swath boundaries. Print quality is remarkably degraded because banding is recognizable on each boundary.




MFD1—Mimaki Fine Diffusion 1

MFD1—Mimaki Fine Diffusion 1

Dithering is an image processing technique, which transforms image data for inkjet printing. Pattern and error-diffusion dithering may, however, generate particular image noise resulting in uneven color printing or tone jumps, even on a high-performance printing unit.
The newly developed RasterLink 6 software,* incorporating the patented* image-processing MFD1, reduces noises due to dithering through hybrid processing of pattern- and error-diffusion dithering, thereby enhancing printing quality.
* MFD1 is available for Version 4.0 and higher
* Patent number: 5230816

Maximum 3.3m2/h* productivity

An array of six staggered printheads increases the printing speed and achieves top-level productivity in the same product category. The UJF-7151 plus supports effective production through high-speed printing at approximately twice the speed of previous models and approximately 2.6 times that of competitive models. Furthermore, by expanding the print area to 710 × 510 mm (28 × 20 in), it is possible to print at the size of 636 × 469 mm (25 × 18.5 in), which is often used for screen printing.
*Print conditions:600 × 600 dpi; 8 Pass

print area to 710 × 510 mm (28 × 20 in)

Ink and media shortage, clogged nozzles, and other minor problems influence stable productivity.
The UJF-7151 plus fully supports continuous printing with reliable technologies.

New printhead’s ink-circulation system reduces clogging nozzles

The ink-circulation system in the head reduces ink settling and thus provides stable ink jetting. In addition, this system removes air bubbles, which plug the nozzle.. Thanks to this function, the nozzle-cleaning frequency is reduced, and accordingly, cost-effective stable printing is achieved.
