Black and Dark Colors Cracking XP-15000

[Outune]

I'm using acroRIP 10.5 and an freshly converted XP-15000 with cheap aftermarket cartridges (yes i know they are really bad if you don't have a damper system with CISS, it can flood it) but the colors are mostly printing great. When it gets to the darker colors like black and dark green it has tiny cracks and vertical lines. I can't find a single bit of info. I blew through 30 DTF sheets trying to get it right with the colors and what not. still unfortunately I can't get it yet, but I will not give up until it prints good. Any help would be nice.

I am using CenDale DTF ink from amazon. I am trying a different type of paper soon, if that does not work I will try DTGPRO ink as I see that's what most people are using. I have attached photo's of my issue.
