That was too easy. I created my target and saved the TIF file but it won't print. ACPU, and PrintTool will take the file, there are a couple of blinks on the 3880 and nothing happens. The file that I created is CMYK 8, covering K from 0-10 and 90-100. In an attempt to isolate the problem, I tried printing one of the default Xrite targets with ACPU but it's just the same. There are a couple of blinks and then nothing. I'm assuming that CMYK is the issue.
What I really want is a TIF in GG2.2 so that I can print it with Cone inks. Taking the CMYK file and converting to GG changes the K values of the patches.
