In matte printing it could use the Photo Black as an extra ink,
so KKkcm and then an ImagePrint, QTR approach for the driver.
Today a friend called who ordered the 4000 this week and was
promised delivery in December. It would be a miracle if that
became true but if it is the first thing I will do is check the
matte printing. There is enough density difference on matte
papers between Photo Black and Matte Black to use it in my
opinion. So that could mean a better B&W quality.
