The totally new SIJ-320UV grand-format LED–UV inkjet printer is a high-performance printer developed using Mimaki's
concentrated inkjet technologies to provide good quality printing with a maximum printable width of 3.2 m.


The SIJ-320UV super wide format printer is a high-productivity model with inks that offer exceptional weatherability for outdoor applications using LUS-120 UV inks that are ideal for applications with curved surfaces such as vehicle wraps and fleet graphics where stretching could crack other inks. It can accommodate single rolls up to 128 inches (325 cm), or dual rolls of up to 60 inches (152 cm). The SIJ-320UV Series printer uses Mimaki Advance Pass System 4 (MAPS4) that reduces visible banding for smoother prints.

Highlights of the Mimaki SIJ-320UV

Mimaki's unique MAPS3 anti-banding system has been improved to MAPS4. Unwanted visible banding on the swath boundaries is reduced by overprinting between swaths with a reduced number of ink droplets.

New image-processing technique reduces tone jumps and uneven color printing

Mimaki Fine Diffusion 1 (MFD1) has been recently added to the bundled RasterLink6 RIP software. MFD1 reduces the noise that is generated in image data during image processing and enables the production of better print results without tone jumps or uneven colors.

Superior inkjet technology

Mimaki's superior inkjet technology accurately places the ink droplets without losing their perfect circularity. This ensures that texts, lines, and edges are clearly and sharply printed.

Smooth-gradation printing

Various ink droplet sizes (large, medium, and small) are precisely placed and exhibit nongrainy, smooth, large-format printing. Dark and light color differences are clearly presented, even in high-speed mode, by utilizing the largest 36 pl droplet size.

The NCU detects and cleans clogged nozzles automatically. If clogging is not resolved after cleaning, the NRS selects substitute nozzles to continue the printing operation. These functions allow the printer to maintain productivity until a technician arrives.

Efficient twin-roll simultaneous printing. A different print job can be printed on each roll simultaneously

Taking advantage of the 3,200-mm printing width, two media rolls can be mounted for simultaneous printing. Different print jobs (or the same print job) can be printed on two separate rolls. The user can select the preferred width separately for each roll, within a specified range (210 to 1,524 mm).

The newly developed, high-performance LUS-120 UV curing ink possesses superior durability and flexibility. These two opposite properties provide beautiful and durable printing on flexible banner materials that cannot be laminated.

Super-draft mode allows rapid printing at a maximum printing speed of 110 m2/h. High-density print mode is available for front/backlit signage applications.
