It's a serious defect in the extreme forms.  

On a re-examination of the various test prints I've recently made with the dye inks, I wanted to note that the HP 72 black only print's metamerism and other qualities are within a usable range.  The gray (LK) is not, in my view, due to tone and metamerism issues.  Nonetheless, the HP 72 in a black only format does have some promise.


For my cards and brochures, however, the Noritsu-Epson combo takes back the business.  I need an LK-density ink to smooth the edge performance of the 1400.  With a dilute Noritsu mix in the setup the 1400 can print good edges and otherwise better deal with printer transport and other print quality limits.

The PK black only image is fairly good, but the gray is warm and has terrible metamerism -- significantly worse than the Claria.  The dmax is not as good, and there is a slight amount of bronzing and gloss differential.   The ink may be incompatible with MIS glossy inks.
