Hello, thank you for taking a minute to read this. I have a Mimaki JV3-130 SP II, and I'm having a strange issue. For some reason my blacks are not printing very well. I've gone into test mode on the printer and tried printing each head color individually and they print fine, but when I print from all four at the same time I end up with prints similar to the images I've attached. The print looks streaked and incomplete. The colors mixed do not matter, I've printed KMY, KMC, MCY, KCY, basically every combination and every combination produces the same results as shown in the pictures attached. I've tried a different vinyl, didn't make a difference. Sorry if I'm not giving enough information up front, I'm stumped. Any insight would be greatly appreciated.
