Re: [QuadtoneRIP] Re: weak blacks in 1400/Cb6 setup

I did agitate those bottles but did that right before I loaded the carts, not the night before. I was under the assumption this was a good thing to do in order to minimize air bubbles. I guess I was wrong about my timing for the agitation.
I learned on another thread to look at the nozzle check more carefully. It's not only to have all dashes print, but we're looking for the steps to be distinct, we don't want two steps at the same level. We also want to see a clean, not ragged, vertical line separating the patch for each cart. My nozzle checks passed that test, so I don't think I had any clogging from suspended ink particles.
But the prints I did after my refill were fine anyway, it's just in the last several days the black has weakened. My prints are now a bit warmer as well.
I do have that 21 step file, thank you, and did a printout with the K-0-100 profile. It's my understanding we are looking for the patch where the scale doesn't get darker. It's a tough call, but it seems to be about 35. However, our qidf shows that entry as 45. I'm not sure how to interpret this as it may relate to my problem.
Well, we're going away for a few days, leaving tomorrow, back Saturday. Maybe I should let this issue simmer a while.
Thanks for the tips!
