Can you expand upon this, I don't understand what you're asking for. Perhaps you can do this with the optional ColorCast module?
Rodney , sorry for responding late, totally missed your post.
Docbees shows curves, amongst others TVI and primary color linearity.
The tvi curves were handy for me to see the original Epson 4900 paper profiles for their papers as they can be identical for different papers, f.i. enhanced matte, archival matte and velvet fine art have identical shaped TVI. So when using a media selection image, f.i. the one from Scott Martin, i found that if i use one of those three, it is valid for all three.
The Linearity curves were the only function that showed a problem in a papaer profile: the actual print was way of f (hard contrast, sort of high key), yet the soft proof was ok. (I do not know what the supplier did to get to this result, he never gave me an explanation. It made me buy i1 Photo Pro 2 to develop my own profiles. The linearity curves showed a strong exponential shape, way off from a more or less linear curve (usually with some ondulations). (looked like a gamma 2.2 was applied but then from light to dark)
I purchased ColorthinkPro after some pondering and posts on this forum, assuming that their device capability graphing would also show this problem. Unfortunately it did not, and raised this need as a point to Colorthink a couple of months ago, sofar no feedback other than a reply that my request was received.
So to summarise: my printer profile generation QC is first a quick check with Docbees, including loading some testimage f.i. a black/white step wegde. If no apparent wrongness i then use Colorthink Pro worksheet to load a range of color values stored in a list(provided by Colorthink), assign prophotorgb to it then the printer profile and look at the resulting change to the image, and also graph both to see in the 3D model how the colors are distributed over the profile envelope. If still no wrongness, then the final check is a softproof and then a print of a testimage, such as testimage from outback based on bill atkinson's testimage. (I use Lightroom for printing)
Would like to have one tool to use for QC, will save time. (and also develop more understanding of how to QC printer profiles(what to look for and how to factor back in into the profile creation process, so i can get the last 10-20% of quality out of the profiling effort)
