Hi Matt, thank you for your reply.

The banding problem was solved after a head clean cycle. I'm still
curious about it, because I wasn't having the banding issue printing
without QTR. Anyway!

I'm pretty much amazed with the consistent results I'm getting with
your curves. After some test printing I found that the best blend
combination that works for me is gloss_cool and gloss_warm at
90%-80%-70% split toning.

Now the only thing I could wish, is to find similarly good curves for
F-A-P on the R2400.
Do you have the printer? Are you aware of any curves for this combo?
