I probably led you astray by leaving out info about L and density.

A and B values are all over the place but the L values and density values are darn near perfectly linear. Wouldn't this mean the device is linear but not grey balanced?
I've heard recommendations to "grey balance prior to profiling". From everything I've gleaned up to now is that there is almost an inherent conflict of interest between linearization and grey balance with respect to ink jet printers, pre-profile. You want predictable, linear response but adjusting any form of linearization curve to get a more neutral grey balance destroys the linear response. Sound correct? The way I'm beginning to see things is that you want to do noting but linearize at the RIP, if possible. Grey balance needs to be handled by the profile/profiling software.
I know that determining the total ink limit is crucial, but what I'm really wondering is how crucial is it or to what degree would it help to determine what the neutralized black would be prior to profiling. Especially when it comes to generating a test chart through PMP measure tool. Seems to me that determining what the mix for a neutral black would be and entering these numbers into the separation dialogue when creating a test chart for profiling would get you allot closer to grey neutrality right off the bat.
Am I leading myself astray?
