Epson F6370 Green Colorshift

[Grizzly]

We have an Epson F6370 and have had green color shift across all products such as mousepads, towels & chromalux panels. Purchased in Jan of 2021, at first, it seemed pretty good. Not my favorite coloring but definitely sellable and acceptable.
Lately, I can't get anything to print without a green shift. It's almost seems like the yellow is too strong or the magenta is too weak. I don't use the Epson near as much as our other printers so I decided to drain the magenta ink and put brand new ink in. It was a small improvement but still not sellable.
The same print on my flatbeds, Seikos or Colorado look as they should with correct depth and gray tones. We use Epson Edge Print for the Epson with the included profiles. We use ONYX for all of our other printers and I've never seen this bad of a color shift.
I've attached a good sample. The one on the left is a chromalux panel from the Epson 6370. The one on the right is off my Seiko 104s.

Does anyone have a profile for Onyx I could try before creating my own. I just want to factor out a variable and see if it's the rip or the printer before I dive into the time it takes to create a profile, especially for dyesub chomalux panels.
I do have a Spectrophotometer and have created my own profiles. Just looking to get something a little better as it's not a big part of our business.


Thanks
Jeremy

(1) this is not a problem you will solve with someone else's canned profile

i know i repeat myself, on this point, BUT a dowmloaded profile can compensate for variations is ink chemistry, substrate & the variations of the AVERAGE model printer

IT CAN NOT compensate for variations and quirks in YOUR PRINTER
(since this is most likely where the problem lies, you need to do the work and perhaps you can compensate and bring your machine. back into spec.)

(2) you haven't posted a nozzle check

(3) i believe the nozzle check from service menu would be te one with the most useful information

(4) a good, long head soak would probably be a good starting point

(5). do you agitate your cartridges?

We use the 6370 as well. We have experienced the same green shift even when printing with Rich Black. We will be testing some adjustments shortly but everything g was fine till recently. But on some prints we are getting a perfect black. I need ti measure the color mix to see the difference.

(1) Someone else’s custom profile can still show whether the rip is the problem or the printer. Onyx does not have a canned profile for this machine available through there printer and profile downloader.
(2) Perfect nozzle check. Always have had one. Great thing about this printer.
(3-4) Don’t really need to do this since I have a perfect nozzle check.
(5) This machine does not have cartridges. It only has an agitator in the black ink and that is done regularly.

you are rejecting the procedure deigned to compensate for this type of problem.
OF COURSE if i had an alternate profile, i would try it first BUT YOU DON'T


good luck with your problem.

Thanks for your suggestions. You're right, I don't have a different profile, this is why I am asking a forum of printers for one.
That's what this forum is for, not sure why you're yelling at me.

Wondering how you solved your problem . I am in the same situation .

We have had something similar. Change all inks out. I used a suction to drain the tanks. My guess ink is going bad. Then do some Rich Black purge printing on junk paper to drain the ink from the lines and ...have the new ink run through. Hope that makes sense.

Thank you I was thinking in that line.

I think the black is the biggest problem. And gets used the least. LMK if that works.

I have a F6370 printer and we use it for chromolux metal printing. had the machine for 3 years. We use the printer everyday but not 8 hours a day. I had to replace the the yellow ink a few weeks ago. After after about 3 weeks all of sudden all my production had a severe green cast. After some trouble shooting I figured it was the yellow ink that I poored in must have cause the green shift. We are using epson edge software and I noticed in the output section there is a tonal range and you can go into the yellow channel and correct for the the yellow similar to curves in photoshop. I am also in process to create a custom profile to compensate for the shift. My question is. I am wondering if I should flush the printer and start fresh. The printer has been bulletproof and I don’t wanna have to deal with shifts all the time. I ordered a fresh set of ink but I also have a lot of expired ink left. I don’t know if I should use it or throw it away it expired in 2022. I noticed there is a very short expiration date and the stays in the machine for a long time. Also I am thinking about agitating the inks weekly, we do agitate the black once a week.

Sublimation ink should not be used after expiration. IT grows mold. I was told this from a friend who is an ink manufacturer. Cheaper to throw ink than fix the printer.

I agree with you. Rather than compensation for the shift all the time it would be better to start fresh we are creating a profile right now to test and after that I will flush. I have a tech scheduled but I am thinking I should try to flush my self. I never thought putting in ink would cause this trouble. This ink goes through very slowly and by the time it uses up a pouch, it will be expired so I will probably run into the same problem again down the road, but at least I will know what to do.
