RE: [Digital BW] QTR vs BO sharpness

2005-11-08 by John Moody

Sure, I have a bunch of things going on here, but I was planning to fire up
the 2200 anyway.
What paper are you printing on, and what ink is in your 2200?  Do you have a
website or somewhere that you can post a small part of the image?  If so,
please post it, and make sure you let us know what dpi you are printing it
at so we are looking at the same size print.

To clarify the QTR-create-ICC issue, that exercise was intended to correct
the “fault” in BO, in that it is not very linear, and QTR is.  Printing the
same file to both processes we should not expect the prints to have the same
tone, unless they have been converted with a profile from the QTR tool.  I’m
assuming you have an i1, maybe that’s a bad assumption; you need that or
equivalent to use the QTR-create-ICC tool.

Best regards,
John Moody

John, May I ask you to try that? I don't have your expertise: I'd be
very interested in your results (comparing best QTR sharpness to BO).

I hate to be the only person reporting a QTR sharpness problem...maybe
I'm really describing MY problem, rather than a flaw in QTR...

...it seems a fault if QTR requires a profile that matches BO in order
to arrive at maximum sharpness. It also seems a fault if it requires
different post-processing sharpning (as it may).

BO obviously does create more contrast in shadow details* than QTR,
but "smart sharpen" of shadows (one of the Photoshop "smart sharpen"
adjustments) in post-processing does cause QTR to approximate BO
sharpness...a matter of tinkering.

* shadow details for Photoshop CS2's "smart sharpen" seems to mean
control of dark areas that contain whites as opposed to control of
dark details contained by whites...in practice this is not the same thing.
