Blue turns purple during drying

[Bengt Backhaus]

Hi.
I have a HP310 and a problem.
As i print a blue logo it looks all blue and correct just after the printhead,
but when it comes out of the heater it's purple?

I'm new to this printer and have no idea where to start troubleshooting.

I print on Oracal 5600 reflective.

Probably your color profile is incorrect. Reflective makes it more difficult but try finding a profile meant for reflective and try again.

Build a profile?
Or, as a poor second choice, manually remove a bit of magenta

I used my go-to profile, which maybe wasn't the smart thing to do.
I tried on normal vinyl (calendered) with a proved profile, and got the same result. (Prints blue and then turns purple during curing.)

Original color is in CMYK, so i changed it to PMS and then it came out perfect.
Coukd it be something in the RIP? I use a rip called "Productionserver 9". Not my choice, it's what was here when i started.

I have had that problem sometimes since a month or so back. CMYK prints pale and not the right shade. But it comes out right when i convert original file to PMS.
