i made a profile using the brightened white paper as the spectra calibration target. it did facilitate reading all of the target patches. the resulting black and white prints made with the new profile are neutral and have good detail in the shadows
I'm glad to hear this offers a work-around for you.
however they are noticeably flat in that the blacks don't have much punch. i tried to compensate by turning up the ink color density in advanced media settings in photoshops print dialogue box but this was not ideal as it just made the entire print darker.
That is seldom a solution that improves results...
is there a way i can increase the dmax in the print by adjusting the profile in advanced editing function of spyderprint app. that is without loosing too much shadow detail or is that just an inevitable trade off.
You can open our Matrix Large test image in Photoshop, apply your SpyderPrint-built profile to the image, then create an RGB correction curve in Photoshop, adjusting only the global curve, not the individual R, G or B curve. Once you get the gray densities as desired, 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.
