Digital BW, The Print

Imageprint may be great and all that.... But I had read many accounts on
the net that the Epson OEM inks vary from batch to batch depending on
what country that are made in. I remember reading that the ink for the
1280 are produced in both Mexico and China and the inks have a different
balance. Has anyone experienced this? If this is the case with the 2200
inks, that they are not produced to a professional consistency, does
that not make profiles and IP4 less of a sure thing until someone busts
the 2200 chips and produces bulk ink of professional quality / consistency??
