Hi, Dana,
I am using a MacPro with 10.11.6 and am printing on an Epson 3880. I’ve downloaded the most recent versions of QuadTone RIP and Print Tool. The K7 paper curves show up fine when I print with inks, but I just went to print with GO for the first time and can’t see any GO curves in Print Tool, nor can I find them on my computer. Any suggestions?
