Align your printheads (located in the Ink Menu).

You also seem to have nozzle performance issues as I see banding in the print. Run a nozzle test print (Ink Menu > Image Quality Maintenance > Clean printheads > Test Print). Based on that run cleanings for the affected head(s).

+1 for head alignment. That is yellow overspray typically caused from heads not being aligned. If that doesn't work, you may need to change the yellow printhead all together.

Just for folks who may search this thread, I copied this from another Latex post I responded to:

In my opinion the only way to get good consistent color on wraps using the L25500 and L26500 is to:

1. Load new heads before color critical large print job (for example a tractor trailer for John Deere) (I save the partial heads for later and just in case)
2. Flip every other tile to help with side to side issues. (usually and automatic setting in the RIP ...Onyx for sure)
3. Ensure the alignments are done manually and regularly.
4. Perform color calibrations regularly to help bring the greybalance back in line.
5. Never print panels for a wrap out of order (i know...this one is impossible
6. Try not to change rolls in the middle of a side (if wrapping a truck or wall)
7. Maintain constant temperature/ humidity in the room throughout the print run.
