it is interesting how much more information this company provides than most others which can be very helpful for a buying decision. although the relation to the OEM inks is not available. On problem is that there are no simple and widely accepted measures to characterize some of the ink properties - e.g. for the fade resistance, a very few companies may show small patches showing the gamut at l=50 in this or that color space, but the gamut is a volume, and nobody posts a volume metric. Nobody posts any information about the black level, on a particular widely available paper like a Canon or Epson or HP glossy or matte paper, only companies taking the effort to generate and provide color profiles for their inks and papers have this type of info available, hidden in the profile data. I don't know if I'm the only one looking for that, at least I know how to get some of such information, by own tests, looking into the profile data etc
