  Anyone want to see for themselves?  Just give me a holler and come on
in to view actual Epson 870 print samples at 200, 240, 300 and 600 dpi
side-by-side and tell me there aren't any differences to be seen.

  Unlike other clueless users who have not collected and examined
hundreds of inkjet and photo printer print samples over the past 10+
years, going all the way back to the original HP Paintjet desktop color
inkjet, and who have not collected over 500+ inkjet print samples from
these various printers, and who have not taken and published any
substantial findings at all, simply see
http://www.silverace.com/dottyspotty/ to have a look, skay?

  There are physical, noticable improvements in all current 6-color
Epson printers from 200dpi all the way up to, and probably beyond,
600dpi in resolution, fine detail, fine text, and subtle shading of
colors.  You can only benefit from using 600dpi or higher if you desire
the utmost best quality Epson photo printers can produce today.  You can
definitely do worse, if you prefer, with lower resolutions.

  If 8-bit WAS good enough, there would be no reason flatbed and film
scanner makers would even bother with more expensive 16-32 bit
scanners.  There would be no reason in the digital camera world for
makers like Sony to use 14-bit HAD CCDs in their digicams, nor toot
their superior, smoother color gradiants and shadow definition in their
images.  And, there would be no reason at all for professional
publications and stock photography shops to even bother with drum
scanning at anything above 8-bits.

  Subjective reasoning that "8-bit's good enough" doesn't cut it in the
real world where an objective analysis of the current state of messed up
histograms show that there aren't enough bits.

  Of course, I'd be more than happy to let you use that 8-bit digital
Xray image the next time you're up for surgery, while everyone else
takes the 16+-bit images.  Let's see then what a misdiagnoses based on
color banding will do, skay?
