I completely agree 16-bit can be a essential quality improovement. Its
like looking through glass or no glass. If someone has no problems while
looking on a surfaces through glass then be it.
If you want the best output in regards of fine shades, be warned of 8-bit
source and 8-bit print files.
Printers capable of showing very smooth transitions of shades, are able to
expose stepping coming from 8-bit source material since years. This is
visible in smooth sourfaces like water, blurred image regions, sky and
other gradient alike image regions. Dithering is a poore cirumvention and
possibly sand for your eyes. Others may be trained and see the artificial
habit of the banding artifacts coming from the 8-bit source material.
Keep in mind that most advertising material, arts prints, arts
paintings behind thick glass and of course monitors have easily
conditioned many peoples eyes to be very tollerant.
That said, for office paper, news paper and smaller than post card size
prints 8-bit might be enough. This maps to the majority of printed
imagery, but not to all printing demands.
