ECO-SOLVENT INK


The MUTOH XpertJet series delivers outstanding print quality and high productivity. The XpertJet 1641SR Pro inherits a platform designed to improve operability and reduce operational workload. It is an uncompromising standard model that balances high image quality and high productivity by adopting a new print head.
The MS41 eco-solvent ink paired with the printer excels in color development, weather resistance, and ease of maintenance. The ink has been certified UL GREENGUARD Gold, making it environmentally and also operator friendly.
The XpertJet 1641SR Pro brings the best “Made in Japan Quality” to various markets such as banners, trade show graphics, indoor and outdoor signs, POP displays, vehicle wrap and more.
that MUTOH’s traditional unique technology “high-precision aluminum rail structure” achieves
that MUTOH’s latest unique technologies “AccuFine”, “i-screen” and “VerteLith” achieve
“AccuFine” is a new extra wide and high density piezo print head, and achieves both high image quality and high-speed printing by dramatically improving the landing accuracy. High quality solid printing with less banding even at high speed
Contributes to higher productivity
*This is different from the actual ink arrangement.
Contributes to higher image quality
The “AccuFine” has longer nozzle lines for im
It achieves up to 200% productivity over conventional model in the same level of image quality.
It achieves high image quality thanks to extremely precise ink dot placement.

Reduces banding and achieves smooth printing by arranging ink dots to consider how they appear to the human eye.

i-screen is a print effect that was built upon MUTOH's Intelligent Interweave technology. It optimizes the AccuFine print head and arranges the ink dots according to how they appear to the human eye, resulting in reduced banding and smoother printing.
We offer a variety of effects, including i-screen, i-screenFine, and i-screenFineX, that match your printer model specifically.



Temporarily prints using selected areas of active nozzles when clogged nozzles fail to recover.
View details

Nozzle Area Select is a safety function that ensures uninterrupted operation.
When nozzles are missing, printing can be performed temporarily using only active nozzle blocks by automatically selecting one of the 6 available function modes, allowing you to continue operation with minimal printer downtime.

Print a nozzle check pattern, exam available nozzle blocks, and select a suitable mode. (6 modes available)

Continue printing using only available nozzles. Printing efficiency drops to approx. 50-60%, but you can continue operation without replacing the print head.

Manages the remaining media with barcodes, enabling efficient media consumption and usage.
View details

When removing media, a barcode is printed on the end of it to record the remaining media amount.
When reloading, the barcode is read by the sensor, and the remaining capacity is recognized, which prevents media from running out during printing and reduces waste.

Media information is also printed in text, allowing you to check it yourself by reading it without having to scan


Automatically adjusts ink landing position during bidirectional printing to achieve sharp, high-quality printing
View details

This function automates the bidirectional adjustment process (which previously required visual inspection and manual input) by printing a pattern and scanning it with a sensor.
This not only lessens the amount of work required from the operator but also saves time and reduces variation in adjustment among operators, ensuring the same results across different jobs.

If the ink landing position is not aligned in both directions, both letters and images will visually double up.

The sensor reads the data and automatically applies corrections

The ink landing position is automatically adjusted, making letters and images appear clear

Automatically corrects the media feed by printing a pattern and reading it with a sensor
View details

Previously, media feed correction was done with a ruler and manually entering data. This functions automates this process by printing a pattern and reading it with a sensor.
This not only lessens the amount of work required from the operator but also saves time and reduces variation in adjustment among operators, ensuring the same results across different jobs.

If the media feed amount is
incorrect, white or black lines may
appear in the printed image

Automatically calculates and
reflects feed correction

It is available to add a module to the print head that can optically monitor the ink jetting. Automatically detects missing nozzles and performs nozzle cleaning. If nozzles are not recovered, the Nozzle Area Select automatically activates to continue printing.
*This function does not guarantee for the perfect accuracy of detection.
PG setting enhanced with 4 steps allows the operators to select the optimal print head height for the media being used. It reduces the risk of print head contact and maintain stable print quality.
Media feeding power is affected by pressure and paper thickness. This pressure mode can be set to four levels: high, middle, low and partial pressure by adjusting the position of the media set lever and the pressure arms, which expands media feed capability. Thin paper and soft media could not be fed by conventional solvent machines now can be supported by setting the pressure low. Furthermore, media cockling can be minimized by canceling multiple pressure rollers individually.
