i was keeping an eye out for your reply to my email question from early last week. i figured that it must have gotten swallowed up by the 4th of july holiday. any how i remain curious as to your response i re-state my question here:
"Since the output profile has already been applied, you just print with No Color Management."in principle i understand this instruction however if i print the progressive curve tests through photoshop and in the print diologue box select photoshop manages colors i am required to select the appropriate icc profile from the drop down menu. isn't this a problem. won't i be adding an extra profile adjustment to the test print.how do i print the curve tests with no color management. do i let printer manage colors or do i just print using the "output" option in the ps print dialogue box. . .thank you.
as a follow up i was unable to build a satisfactory curve in order to open up detail in the shadows while still printing a proper black. no matter what i tried, the profile i made using the custom white calibration (as you suggested substituting the kirkland gloss paper white paper in place of the spectra calibration tile) just seemed to have a limited gamut. disappointing.
i finally after reading a luminous landscape review of the epson 3880 which talked about the accuracy of epsons advanced b&w option.
i printed with the printer managing color on the abw setting and was surprised to get beautiful results. punchy black with detail clearly rendered.
so now what do i do. does this mean that the spider spectra i am using is not designed to profile optically brightened papers such as the kirkland gloss i am using. this would be unfortunate as i do feel the need to fine tune my printing by continuing to build custom paper and ink combination icc profiles. is it possible that the more recently produced versions of the datacolor spectra are designed to deal with these issues more efficiently.
i appreciate your help . . .

thank you for your thoughts on this.You can open our Matrix Large test image in Photoshop,i am able to do thisapply your SpyderPrint-built profile to the imagehow exactly do i proceed to apply my spyderprint built profile to the image.Edit > Convert to Profile. Choose your Custom SpyderPrint profile.then create an RGB correction curve in Photoshop, adjusting only the global curve, not the individual R, G or B curve.i think i can do the aboveIts a matter or making small adjustments to the areas that you want lighter or darker, printing tests, making further changes, saving each generation of curve adjustments, until the print results are just as you want them. Since the output profile has already been applied, you just print with No Color Management.you can then import that RGB correction curve into SpyderPrint and apply it to the profile to get these results directly from a new version of the custom profile.how do i do accomplish this import and the application of the curve to the profile.Launch SpyderPrint. At the fork in the road, select Choose Existing Measurement Set. Select the set for your profile. Move forward to the SpyderProof View screen, and choose the button for the Advanced Editing button. On the SpyderProof Edit screen, select the button named Import Curves File, and navigate to where you have saved your Photoshop Curves file. Once selected, it will be applied to your profile. Now save new version of the profile, named to reflect the addition of the curves.michaelC. David Tobie
