Digital BW, The Print

Hi Paul. That undoubtedly was me you refer to here. I did not mean it in that sense as I did say they used the cheapest consonant with achieving their goal of an even fade rate. If you look back at the patent I believe it's actually stated that way as an intent. In any event, a hue shift will be obvious earlier than a slight density loss might be so their goal is laudable in itself. I don't remember if they mentioned a blend of more expensive pigments that could achieve the same thing with potentially an even better longevity overall.They are in business to make a profit and remain competitive both so cost has to be a factor. My comment was not meant to be a slam.

Regards,
Duane

Using the very best color pigments may not be justified if they cause the ink to color shift.  For example, if there is a super cyan that is stronger than any magenta, it makes no sense to pay more for the super cyan and end up with an inkset that green-shifts.  So, it is rational to save that money.
