Twin-roll printing

Taking advantage of the 3,200 mm printing width, two media rolls can be mounted and can be printed on simultaneously*. This function enables operating different print jobs at once. The user may select the preferable widths separately for each roll within a specified range from 210 to 1,524 mm. Each media width and the distance between the two media rolls are automatically detected.
* The same media type should be used when printing on two media rolls simultaneously.

Eco-solvent ink “CS100” & “CS200”

Affordable yet reliable solvent ink “CS100” & “CS200”


The series of CS ink of 2L bottle type are more affordable than conventional cartridge, which have exceptional stability and low propensity to clog nozzles.

The CS ink also brings the same high Mimaki standards for color accuracy, image durabilty and weatherability found in other conventional Mimaki solvent inks.

* CS200 is available in specific counrties only.

Mimaki’s Core Technologies

Mimaki Advanced Pass System (MAPS4)

MAPS is designed to prevent banding. With every pass, it uses a unique algorithm that calculates the most effective way of jetting the ink drops to avoid visible banding. This constantly changes depending on ink color, coverage and printing speed.

Mimaki Advanced Pass System (MAPS4)

Nozzle Recovery System (NRS)

Without the nozzle recovery function, when printing and nozzle clogging or failure occurs that could not be resolved by the nozzle cleaning function, printers have to wait stop until the Mimaki service team arrives. When it comes to this function, even if nozzle washing has no effect on a troubled nozzle, the print image quality can be retained immediately without slowing down the print process.
* The recoverability of this function is limited.
