Forgive me for my ignorance, but I'm a little unfamiliar with RIP's in general, and was wondering how media profiles work for different paper/canvas types? Specifically, I've ordered some Satin Canvas, and the manufacturer doesn't seem to offer any Onyx profiles for the media. I've noticed the same for the Epson media I've purchased. I can get ICC profiles, but cannot seem to find profiles for Onyx.
How does this work exactly? Is it normal to not get an Onyx profile for media types? If so, do you create your own, or choose an existing profile and hope for the best?
Any tips / tricks / input would be greatly appreciated.
