Did you separate tiles in the rip or did you separate them before you brought them into the rip software? Sometimes separating them before bringing them into the rip can cause it to rip the colors at slightly different values even though they were created with the same values. Especially if that panel was a different size from the others.
Here is a screen shot of the prints presets.
color correction probably little over a month, print heads all have between 1100-1600 ml of ink fired, expect for one Y/M has little over 4000.
I love latex printers but this is their biggest weakness....They use heat to cure the ink which is very sensitive to environmental changes, temperature, moisture, print speed, and so on. And because the printer runs over a period of time the latent heat at the beginning of a run is cooler than after is has been printing for awhile. I used to use an HP L28500 and it was way worse then the latest series of HP latex printers. My old one didn't use optimizer or have an on board profiling system, HP added those features to alleviate the issues you are having. So the solution sounds complicated but in practice it's very easy.
1. Print your panels in installation order...i.e. print panel 1, then panel 2, then panel 3, and so on. This minimizes the color shift as the printer heats/cools throughout the run. Any color variation is hidden because the panels that need to match were printed next to each other.
2. Rotate every other panel by 180 degrees. That way the left side of say Panel 1 prints on the same side of the printer as the right side of Panel 2. This helps minimize color shifts because as the printer begins each pass either left or right it takes a split second to be jetting the inks properly...so the left/right edges might have a color shift before the jets are firing properly. Also in a latex sometimes the heating elements are a little hotter/cooler on the left/right of the machine, this is more common the older the heating element gets and wears out. But rotating every other panel allows the right side of one panel to be on the same side of the printer as the left side of the next panel...reducing any color shift.
3. Lastly add a small printing gutter to each side of the prints. It's an option in your RIP software. This prints pure inks (CMYKLcLm or whatever your inkset is) in small strips along the edges of the roll. Again because the latex gets so hot and is so sensitive to environmental conditions that if you are running a print that is using heavy amounts of say Cyan but not much Magenta, then over the course of the print run the Magenta head is exposed to a lot of heat while not firing a lot of ink. Then when it comes to a point in the print job where it needs to fire the Magenta the heads take a bit to recover and fire the jets fully. But if you have the printing gutters then the heads a kept "fresh" and constantly supplied with ink and not drying up with the heat.
It sounds tricky but it's simply a matter of printing in order, rotating every other print 180 degrees, and clicking a check box in the RIP for the gutters. This will minimize any color shifts, and honestly I do these on all of my paneled print jobs regardless of the printer technology it's just a good practice and yields the best results reliably.
I know this is a super old post but wanted to chime in here. We literally had the exact same problem when we first got our HP360. We had a very similar looking wrap to print for an RV. It had greys and beiges in it. And we had the same issues that you did. Nothing seemed to solve it. Here we are 9 years later having the same issue while printing solid beige panels. Colors will shift from the beginning of the roll to the end. They are not consistent and never will be. So we are going to have to start and stop every so many feet and potentially keep reprofiling over and over again until we get through this one last job. AND NEVER AGAINEquipment, material, Software used.

The color shift is so concerning, my immediate thought it was switching rolls in between prints, printed all I could on the roll I had open and the rest on the new roll, same with the laminate, switched once we ran out, BUT then realized maybe not, because there is color shifting on the same roll, same laminate.
same color profile on all prints they were all send to production manager at the same time, only ripped one at the time when I was ready to send to printer.
could it be production manager?
inks?
printer?
I'm so lost and kind of sick to my stomach!
Anyone have any thoughts?
Check out if your inks are expired. This will make pigments settling to bottom of your cartridge making the ink color completely random.I know this is a super old post but wanted to chime in here.

Did you create a new media preset (do not clone) and then create a new ICC profile?Yes but when you the calibration the colors look great. I just bought a HP Latex 570 from another company. It was very well maintained by HP it's whole life. It came with an extra set of inks. The ink that it is running all say expired but I have been running HP's and Mutoh's for 20 years have never run into this problem until now. Everything I print has a pink shade to it?! I have run flexi but thought it was time to change. I downloaded Onyx Go and thought it might printer better. Same issue? I am going to replace the inks I think are causing the issues. I will update when done. Unless someone can think of another reason?
