Prior to getting my NEC 3090 and profiling it with SpectraViewII, I would send B&W images to my HPZ3100 as RGB files, with application-managed color. I was always stunned by how neutral the grays, whites and blacks were in the prints, regardless of what paper and Z3100-generated profile I used. They always appeared nuetral in the Photoshop soft-proofs, as well. The now-defunct monitor was a CRT, profiled with HP's APS.
After calibrating and profiling my NEC 3090 with SpectraView several times with different target values I finally arrived at a configuration that matches my prints as well as they had been with the old monitor. The settings are:
1) Gamma: Native
2) White Point: D65. The info page in SpectraView says the actual target is 6503 k, and the value measured by Spectraview is 6530 k
3) Luminosity: Target 110 cd/m2, actual value 109.8.
4) Primary color values: Factory values, as I am using the i1 Display 2 colorimeter.
I am printing on Epson Premuim Glossy, with an APS generated profile. Whether I profilied the monitor with native gamma or with a value of 2.2, when I process an image as B&W it appears neutral on the monitor and also when softproofed in CS4. When printed, it looks warm, very slightly tending more toward yellow. Since this does not appear in the softproof, I guessed at a correction toward the blue and the print improved somewhat.
My main concern is where the discrepancy occurred. I tried printing some old B&W's, and they came out neutral, so there is either a problem in the monitor's profile or in the softproofing. I stand in awe of how little I know about these things
