Title: Re: Consistency of inkjet inks
We run through about 250 feet of media a week on our 9800 and I have never noticed it being off that much. From time to time I have seen a difference of up to 1.3 dE but never 3. Im trying to check the linearization at least twice a week but its so stable that I don’t feel bad if I have to let it slide. I do however perform a nozzle check 3 times a day. I have found that in the winter (its 5 below here right now) the nozzles seem to clog more often due to the lack of humidity.

Does anyone has any input on the Epson K3 inks quality?
Someone replaced Cyan in my 9800 last night and did not tell me. When I got to work and printed some proofs they were way off my FinalProof. I noticed that pure solid Cyan was very, very red. After I noticed new ink in the printer I verified calibration (gmg mx3) and I was over 3 dE off.
Does anyone knows if Epson checks inks for hue changes?
How often do you re-calibrate (or do linearisation in some rips) using Epson 800 series engines?
How often do you clean nozzles? I noticed Epsons cloogging much faster than my HP (5500 and 1050).
How about HP Z series engines, are they more stable?
Canon Lucia inks? Any better?
What is affecting color so much? Here in NYC is very cold and dry now, but would humidity affect ink hue that much?
