here is illustration that will help you understand what gamut is:

In Paul's diagram, there would be another triangle type shape showing the colours achievable with your sublimation inks which would be smaller and inside the CMYK one.

hi!
I just had a look on your profile and i must say it has larger gamut then inkjet sublimation printer. so i dont think profile is the problem.

the white gamut is yours.

The problem in this particular instance was because of how Corel treats gradient fills. If you ever need to go from a specific pantone to white it is always better to do it as a blend with a white box as a fill of 0% of said pantone. Gradient fills in Corel and handled by RGB process so will never do well with blues

What file type are you sending to RIP? I work with large format prints, CMYK, and use Adobe Illustrator for preflight, and gradients are always an issue. Some of my workarounds, and I don't know if they apply to your process, are to convert the AI file to TIFF rather than PDF to RIP. Sometimes I use Photoshop to convert the PDF to TIFF. I don't know if these steps will help or not, have no experience with Corel for years now.
