i am not new to color calibration, nor building my own color profiles
i have tried everything in the book and just have come to realize the only conclusion is that the technology is just not there yet.
was it a huge waste of money, you betcha
will i keep trying to get it to live up to our quality standards, for now yes
i have tried the Tiff route, better but still very poor in the end, i have finally talked to tech support and been going through the machine fixing issues with it that keep popping up, our large format printers never have issues and didn't cost all that much more, so it is just a head scratcher as i shrug my shoulders
but "training" will fix all my issues i am told repeatedly...

..... all my other machines the techs come here, but they want me to train on a machine that i will never see again in california.....
