Digital BW, The Print

BUT do you print and calibrate (densitometer check) the contrast difference,
however so slight, between the two resolutions?  Then, adjust so that both
prints are exactly equal in contrast and tone before bringing in the
neighbors?

Why would seven inks give no dots and four would create a problem?  Are you
calculating --and controlling-- dot gain?  There is no mention of which
paper, very much a factor in dot gain.  In fact some papers blasted with
seven inks would saturate so badly your friends and neighbors wouldn't like
them either.

What I am not understanding is why you have friends and neighbors looking at
the prints, then you are deciding why they see a difference (dots)?  At
least, that's what I take from what you said.  Just doesn't seem objective.

I am not questioning all your calculations.  It just seems to be a hard line
approach --if you don't have this it won't work.  Would you please explain a
little more?

==> Black = 100%
==> Dark Gray = 55%
==> Medium Gray = 10%
==> Light Gray = 5%

==The defaults for the PiezoTone inks densities from StudioPrint 10 is:
==
==Black = 100%
==Light black = 50%
==Very light black = 20%
==very very light black = 7%
==
==This is what I'm using (that is, I haven't changed the 
==default settings) printing on an Epson 7600 using PiezoTones 
==on Hahnemuhle Photo Rag 308gsm, with StudioPrint.

==If you really want dotless, I think you need to consider 
==either the PiezoTones, or the MIS Ultratone inks for a seven 
==channel printer like the Epson x6xx printers.
==
==I would have to take issue with your statement that "This is 
==only true at VERY close viewing distances and of no 
==consequence for a print hanging on the wall or even prints 
==viewed on had at half arm's length." 
==I've run some unscientific tests, and people other than 
==myself (that is, non-photographer, non-printer neighbors) can 
==see the difference between PiezoTones printed at 1440 and at 
==2880 from farther away than "normal viewing distance." The 
==only difference I can see with a loupe on these test prints 
==is the level of dotiness. I think less dotiness is clearly 
==visible (at least off my printer) from normal viewing distances.
==
==And, as Tyler says, hex tone inksets are even smoother. The 
==difference being the distance between the dots.
==
==Is it necessary? I think it is, yes. Of course, YMMV.
