Yellow hue with Neutral K7 E7900 and Hahnemuehle photo Rag

I am getting a distinct yellow hue in the midtones with the Neutral K7 inks on Hahnemuehle photo Rag with 7900. I have used this paper for years with neutral, warm neutral inks of the 7600 and never had this hue. I also tried Moab Entrada, Epson Velvet fine art and others with the same hue. This is new to me. would I see this with Cone type 2 papers?

Dear jfammart, can you private message me with your batch# for shades 2,3,4 and 5?

best,
Walker

I am getting yellow in the highlights of my 7890 K-7 Special Edition ink set. I have run several paired channel cleanings, beyond the initial fills I did. I understand that yellow is the most troublesome ink but I wonder if anyone has a way to clear it out without wasting a lot of other ink and paper?
Thanks,
Paul

I don’t know what you mean by “batch#” in those shades. also, I don’t know how to private massage you.
please explain.
