[Leica] LR4 Soft Proofing

[kcarney1 at cox.net (Ken Carney)]

Right, I always soft proof when printing in color (SFAIK there is no way to
do that in grayscale, except for some really time-consuming curve building
in the ImagePrint RIP, which I tried and abandoned).  With a good profile
for the paper/printer and uniform lighting, I can usually match the
(calibrated) monitor on the second if not first try (a letter-sized print on
those tries, though!).   Usually it is just a curves adjustment and maybe a
small saturation bump.  Most of my printing is b&w, so soft-proofing is n/a.
That requires a RIP, though I have been really pleased with the Epson
Advanced B&W settings on "fiber" inkjet papers such as Harman and Epson.
Whatever, the ratio of keepers is much better than in the darkroom days.

And you need to have created and installed those profiles from elsewhere
before you can select them for printing or soft proofing. Those may be the
'canned 'profiles from the paper manufacturers or custom profiles.
Notice the perceived difference when a 'white' border is displayed in that
soft proof mode though.

Actually the new LR changes effectively duplicate Photoshop's printing
capabilities with more smarts added (resolution and colour space background
automation for two).
With most monitors in any case the luminance and contrast will not echo well
what the print displays (not even considering the transmissive vs.
reflective conditions). Few monitors can cover more than sRGB as well but
good inkjets can approach AdobeRGB.
A print on good Photorag might have a contrast ratio of maybe 150:1 compared
to maybe 10000 :1 of a common LCD screen.

High end monitors like the best Eizos and NECs confer a lot of advantages,
including in these areas but maybe that is another conversation.

Cheers,
Geoff
