If you are using Flexi 8 and running on the 1204 VJ Try using either the Mutoh One in All preset or the Oracal 3651 Preset. I prefer the Mutoh All in One profile, much more.
Also you need to check that if you are trying to print vector images, then you need to make sure to set your Vector Settings correctly.
Open Rip & Print
Go to the Advance tab
make sure you have your profile preset
Click on Color Settings
Click the rendering intent tab
Change Vector, Text & Gradients, to NO COLOR CORRECTION
leave everything else alone and give it a try.
Let me know
