When I bought my Mimaki UCJV330, I paid an expert to come in and create profiles for it because the default profiles in Rasterlink were terrible. I shadowed him the whole time to learn and he was more than willing to educate me. There is a lot to know and I won't pretend to know everything. He did say if I wanted to create my own profiles, to go to Ebay and find an EFI spectro. It's basically an X-rite with different branding. When I switched from Rasterlink to Onyx Thrive, I used it to create profiles for the UCJV330 and it worked great at a fraction of the cost of an X-rite. I got the ES-2000, if anyone is wondering.
