Digital BW, The Print

A while back I tricked ImagePrint into only using Black and Light Black inks
and remembered the result was very warm.  I just dug that print out and
compared it to the Epson RIP prints I just made.

While the Epson RIP print is warm, slightly sepia looking, it's not quite as
sepia as the Matte Black + Light Black only print. There may be some other
inks being mixed in there.  Tomorrow, I'll look at it under the microscope
at work and see what's going on.
