>From my admittedly limited amount of testing on both the Epson 4800 and the
HP Z3100 (the latter thanks to Julian Mussi's kind intercession), I have
been able to notice that a deep black (R 0, G 0, B 0) printed on Premium
Luster on an Epson 4800 reads as low as an L* value of 2.8, whereas on satin
paper with a Z3100 it reads at L* 4.4. Though I view both L* values as very
acceptable for fine art B&W printing, there is a noticeable difference in
the sensation of deeper contrast resulting from the combination of Premium
Luster stock with K3 inks compared to the satin print from the Z3100, though
it may not be seen as a dealbreaker.
This may be partly due to the fact that the K3 printers (used in Advanced
B&W mode) also use other inks (cyan, magenta and yellow) besides just the
blacks, which probably accounts for the higher density producing deeper
blacks. And somehow the presence of these chromatic inks doesn't seem to
affect the excellent overall neutrality of B&W K3 print under a range of
illuminants either.
Incidentally, the image I printed on the 2 media for my test (on Premium
Luster with K3 inks and HP Satin paper with the Z3100) shows more "body" in
the midtones in the Premium Luster/K3 print, which is something I like
better for my own images. The HP print appears a touch too "weak" by
comparison.
As a final note, the Premium Luster paper has a much lower OB content
(optical brighteners) than the satin stock, for whatever that is worth
noting.
Have others done similar tests (possibly much more rigorous than mine)?
