Must be some method of neutralizing the PK (black ink to neutral as my PK black alone has a tinge of green by itself so they must be calling in some magenta ink to counteract that. Took three test pages just for B&W now, but it seemed to do a lot better in producing a neutral B&W image with the 3rd page being mostly B&W test patches and some rows with color added to null out any tint. I played around a bit with the newer xrite i1Studio software and its new B&W profiling. So I would recommend to not waste your time with this vendor. And if you inquire them about it they will ask such questions that are worse than your tax office. But there is a problem here too, they do not give even trial version of their software. Then there alwancolor with their spectro tech called Hydra Profiling that is not mathematical but spectral ICC creation that needs few patches instead of thousands.

Now they fed up with that and make same color server called zepra.

Then there are players like basiccolor with 'their' or better say copycat software from ColorLogic since they always update their software to previous version of ColorLogic software. Xrite even can't explain why certain patch amount targets have many near grayscale patches while other don't.

The interface is very bad, and no decent documentation even now. I1profiler i no doubt great compared to older generation software, that is under the hood. So same model spectros made in different factories were reading wrong. The XRGA came to life as means for instrument standardization because the former gretagmacbeth employers by accident mixed etalon whites they used for spectrophotometer manufacturing. But since then no improvement came, quite the contrary. For those that don't know they were not able to make decent hardware so they bought their competitor gretagmacbeth. So since gretagmacbeth was bought by xrite. Well I can say that in niche market like color management problem is that software maker get away with mediocore software for premium price.
