Digital BW, The Print

Thx a lot Paul. 

I think I'd better stay with HPR. BO mode gives
me quite neutral tones in high lights and slightly warm shadows (Lab B
just under 4), which is not that bad finally. 

Last question: I usually
consider a tone as neutral when Lab B is between 0 and 2. Am I right?


Regards 

Sylvain.

http://www.paulroark.com/BW-Info/R1800-No-OBA-Paper.pdf [1] This was
part of the 1800 3-MK write-up. The tones are the same as those with a
1400 BO, however. For brightened papers, see
http://www.paulroark.com/BW-Info/R1800-OBA-Papers.pdf [2] If the graphs
are not self-explanatory, see
http://www.paulroark.com/BW-Info/R1800-Paper.pdf [3] For dilute Eboni-6,
see http://www.paulroark.com/BW-Info/Eboni-6.pdf [4] In general, Eboni
black only or the 3-MK approach appears to be the closest thing we have
to a neutral 100% carbon image. Diluting the Eboni causes the tones to
be warmer on most papers. Also, the 1.5 pl printers are a bit warmer
than the 3 pl printers with dilute Eboni. For a coated inkjet paper, the
Epson Hot Press papers -- both natural and brightened -- should be
tried. If toners are used to cool the carbon, I'd recommend OEM inks.
Epson LM and LC may appear to have done the best in
http://www.aardenburg-imaging.com/ [5] testing on at least a few papers
I've checked. But, all we have are the 100% C and M patches to rely on.
Check out the graph on page 6 of
http://www.paulroark.com/BW-Info/4000-6K-Plus.pdf [6] . Some paper takes
to little color to neutralize the carbon, that I doubt the fading of top
color pigments would be of much consequence. In short, once you find a
paper that you like and is relatively neutral, it may be that getting it
to exactly the tone you like takes so little color that it's not
particularly relevant to longevity. Remember that 100% carbon is a
benchmark. The more color added and the quality of the color added are
what cause the problems. Paul www.PaulRoark.com [7]
