Why the ink series matters more than price

Eco-solvent printers are set up for a specific ink series: the ink chemistry, color set, chips or cartridges, and the color profiles in your RIP. Putting the wrong series in can mean color shifts, profile work, or a full line flush. So the first question is always: what printer do you have, and what ink is it running now?

Genuine Mutoh MS41

MS41 is Mutoh's current eco-solvent ink for the XpertJet SR series. Mutoh engineered it for the XpertJet 1641SR and 1682SR. It keeps the outdoor durability and abrasion resistance of earlier ECO Ultra inks and adds a wider color gamut and improved dot gain. It comes in seven colors (CMYK plus light cyan, light magenta and light black) in 1-liter bags, which means longer runs between changes.

If you own an XpertJet 1641SR or 1682SR, MS41 is the straightforward choice.

Impact Eco-Solvent Ink

Impact Eco-Solvent Ink is our own brand, in CMYK 1-liter format. It's formulated to replicate the color characteristics of Eco-Sol MAX and Eco-Ultra inks, with low odor and plug-and-play setup. Its listing describes water resistance and outdoor durability without lamination, and good adhesion on coated and uncoated media.

It is not a genuine Mutoh or Roland product. Before switching, confirm that your printer's current ink matches one of the series it's made to replicate, and that you only need CMYK.

Switching inks safely

• Use up or remove the old ink according to your printer manufacturer's procedure.
• Don't mix different ink series in the same line.
• Print a nozzle check and a color chart after the change, and compare against your profile.
• If your printer uses chips, confirm the new ink supply works with your chip setup before ordering.

Questions to answer before you order

1. What is the exact printer model? Write down the full model name from the label, for example XpertJet 1641SR rather than just "Mutoh."
2. What ink is in it today? Check the bag, cartridge or bottle label for the series name. That tells you whether MS41, an Eco-Sol MAX class ink or something else is installed.
3. How many colors does it run? A seven-color setup with light colors needs a seven-color ink. Impact Eco-Solvent Ink is CMYK only.
4. Bags, cartridges or bulk? Confirm your printer takes the supply format you're buying, and whether it uses chips.
5. Do you have a profile? If you change ink brands, plan time to load or build a color profile for each media you print.

If you can answer those five questions, ordering the right ink is simple. If you can't, send us a photo of the ink label and printer model and we'll help.

Supply format and storage

Both inks here come in 1-liter sizes. Store unopened ink upright, sealed, at room temperature and out of direct sunlight. Check the date on the package and use older stock first.

Keep the printer healthy

Ink is only part of print quality. Dampers, caps and wipers wear over time. Our team has 25 years of technical experience with these printers, so call if you're seeing banding or missing nozzles after an ink change. For DTF supplies, see our DTF printhead checklist.
