We vectorize and have many of our images printed onto vinyl banner, however we keep running into the issue of our print coming out darker than our CMYK and RBG images on screen. Is there a profile already built into either program or is there one I can download specifically for CMYK vinyl banner printing?
You have to set up color management for your specific situation or have an expert set it up for you.
It highly depends on the printer, the inks and the paper used. Also: the system itself needs to be calibrated and profiled.
