that is not the case. In fact the only way to minimize metamerism failure with desktop Epsons to the lowest possible degree is with a RIP or special driver. Then the black inks can be used for entirety of the tonal scale and color inks in small amounts then brought in to correct hue. The metamerism failure differences side by side between the EOM driver and QTR driver with a printer like the 2200 will be striking, even if under one light source they are nearly identical.

He describes the situation correctly, your "either/or's" are not quite right. There are other important variables like the generation of Epson/driver and how many light black inks that alter the outcome of simple OEM vs QTR comparisons and the trade-offs involved.

Bottom line for your 2200, if you keep your OEM inks, QTR will help your B&W output considerably.
