Hp Latex Printer issues with matching old jobs color

I’ve been dealing with a difference in shades with my printer. I have laminated and done test prints to match and nothing matches my old color. Same printer, same color codes, same files being printed. Just different shades.

I’ve checked RIP logs to make sure that all the settings are the same but it just prints this blue that is slightly more purple and deep than the blue I originally started using. My AI is set to

sRGB- IEC61966-2.1
CMYK- Coated FOGRA39(ISO 12647-2:2004)


The pitting could make it look off although I don’t think so. I’ve tried messing with file setting, making sure I’m printing the same file type, trying others, going back and grabbing color codes of finalized prints to make sure it’s the same code.

Any tips? IMG_0468.jpeg

reprinting a patch of an old job?
cause colors fade over time

also, random ink starvation could happen between printing one day and another day.
old rolls vs new rolls could accept ink differently
printheads could miss a few nozzles between their lifecycles
lotta variables here, sucks.
best you can do is create some swatches and try to color match with a "new" temporary file.... figure out what CMYK values your file was originally printing out, and the make a crapload of +/- CMYK values at 5% increments

Been doing swatch tests. Looks like I’ll have to continue thanks! Also side notes: I have made sure I’m running the right substrate as well as print settings for

How old is the old print? What surface is this on? Would the original print fade any?
It is a known issue with HP Latex, it was addressed with the gen 4 printheads.

Agree with the rest. Your heads could have been degraded at the time of printing, or they could be degraded now. Either way, it's very hard to match color, months apart, on an HP Latex 365, unless you recalibrate fairly often.
I would make sure all the heads are fresh and recalibrate. That way, even if you have to come up with a new color now, you'll be able to match it better in the future with the same setup.

How were the heads when you ran the original job? If magenta head was changed shortly after, then that could explain additional warmth on original.

worst-case, you could always design the patch to be an appealing "racing stripe" of sorts and just make it perfectly imperfect
