Have your tried using a perceptual rendering intent instead of relative colorimetric? ICC profiles allow for six lookup tables (LUTs), two for each intent. There should be an input to connection space table, and a connection space to output device table for each intent supported, and even an inexpensive profile builder should support tables for at least perceptual and relative colorimetric.

Yes, Perceptual intent produces the correct purple block. There is still something wrong with a lot of the R3000 RR profiles as that purple block soft-proofs blue with Relative and soft-proofs as purple with Perceptual. Other RR profiles, Ex: Paper Canvas, soft-proofs purple for both Relative and Perceptual. All my custom Red River paper profiles made with the Xrite I1PRO or Xrite Pulse system soft-proof as purple with both Relative and Perceptual.

Most users use Relative intent, I don't, I use Perceptual 99.9% of the time as I print mostly portraits and find the out of gamut remapped lighter colors of Perceptual more pleasing. This is why I have never noticed anything wrong with RR supplied profiles when I first got my R3000. My custom profiles eliminate all issues. Relative intent gives more saturated colors, especially with BP Comp. turned off. So I can see where some users may be upset with not being able to use it correctly with some prints. The Epson profiles also soft-proof the purple correctly with Relative or Perceptual. RR has a problem.

Bob, does it matter if one use a specific rendering intent used for printing the test patches during the production of the profile?

Will the user then be "Locked" to the specific Rendering Intent used during the production of that profile when one prints using that same profile?
