I've also leveled the ink as the yellow was lower than the cyan... but it still persists... ughhhhhh!
Cyan Bleeding into Yellow Channel
I've been printing a 100% yellow print perfectly for about 25 shirts and suddenly i'm getting cyan into the print creating a green tint. I changed the damper for yellow and cyan but it still persists. I'm getting a perfect nozzle check. Any clues?

I've encounter this kind of problem some time ago with my Epson printer. possibly the some fiber or other dirts in the surface of the print head. try to check carefully the surface of the print head with a mirror and wipe with print head cleaning utilities you have at hand.
How's the wiper? Is it clean? Check capping station also. Have you changed cyan ink levels?
I've turned the cyan level down to zero and still getting greenish tint... wiper and capping station are clean...
Re RIP it. I would also look at a delaminated head but you said the nozzle check looked good. Does the ink in the damper look pure, might try sucking the ink out of the damper. Encoder strip might need cleaned probably not but would not hurt. Be sure the capping station is functioning properly, if ink back up in the capping station. Sure it's the cyan not the black, black and yellow make a green, my black will back up into the yellow if the valve to the waste tank is not shut off and I put a bit of cleaner in the capping station overnight. When did it start in the middle of production, points to dirty head, capping station / wiper ink build up kinked drain line. Next day and you put cleaner in the capping station??
what do you mean "valve to the waste station is not shut off" It looks like it's draining fine into the waste tank. cleaned the bottom of the print head and still getting a clean nozzle check... the black ink level was lower, so I filled it and testing now...
Ok you may not have a valve, in which case is the problem occuring after a night of sitting and you put cleaning fluid in the capping station, even a few drops?? by the way if it is the black and not the cyan that is mixing making the black higher might show up as making the problem worse. We will see.
When this happens again stop the printer and move the print head out so you can look at it, is there any indication of black or cyan ink on the face of the print head? It has to be related to the print head and/or capping station. The RIP is going to send the same data time after time if you are not sending a different job - meaning if it is greenish on #25 it should be greenish on number one. The yellow is becoming contaminated at some point. Delaminated print head is possible, though uncommon unless something has been done to it like forcing liquids through it with too much force or using an overly aggressive cleaner (like pure ammonia or other harsh chemicals) too much or for too long.
Does the problem seem to show itself after a head cleaning? Does it persist from that point on or does it rectify itself after a print or two? Make sure the wiper and capping station are clean as well (maybe even consider replacing them if they are more than 6 months old).
Hope this helps.

Thanks for all of the help... it appears to be better now after cleaning everything several times... there was build up on the printhead and it seems like the capping station and wiper are constantly messy. Is this normal? I bought it refurbed from Mesa SW in April, but it seems to be a recurring problem. I will check with them. Thanks again for all of the suggestions!!!
the capping station (wiper, pump and assembly ) is a wear part so you do have to change it out...

sells the entire set for $25.00 .. depending on the age and how many prints you have done it will need to be changed.
