Hello Randy!
What kind of driver did you set up? Did you use RGB driver or CT CMYK
driver or HT driver? What media did you choose in printer settings in
RIP? Did you connect RGB profile to the same media? It's very important
to connect profile to correct media used during printing testchart.
PS: I prefer to use CT driver and to build CMYK ICC profiles. I use
i1Profiler for icc profile creation and usually get perfect results, at
least 2 times (usually 3 times) better than ISO 12647-7 tolerances.
Best regards,

I profiled an Epson 4900 with an EFI eXpress Rip. After using the Rip preset "Turn Color Management off" I printed a TC918 RGB color chart and read it with my Isis using Colorport. The data was saved as CGATS and an RGB profile was generated using EFI Profiler Suite.
I imported the new profile into the rip and connected it as an RGB profile.
The profile was poor. Too dark overall, various hue errors above Delta E 3 and a pink cast in the 75% to 90% blacks. I was able to edit it to respectability but would like to know how to get it right the first time. The new profile is being used by the rip as later versions showed the expected changes.
Any ideas what went wrong?
