I am trying to find a good profile for oracals 3640 that is compatible with colorrip on the sp-300. So far I have been able to download 3651 and 3621 from the oracal website. they dont work well...cause they arent for 3640 i'd imagine ... I have had good success with the generic pvc profiles and the GCVP mode 2 and 3 profiles. Is there a profile specifically for 3640 AND my set up?
