QTR calibration stopped working with latest OS X update; work around?

QTR calibration stopped working with latest OS X update; work around?

2013-06-07 by Vincent Wan

After the latest OS X update 10.8.4 QTR in calibration mode prints separation file in calibration mode strangely: K, C print but with odd densities, M stops printing at 50, LC at 5, Y at 20 and LM not at all.

Deleted printer, QTR in lib/, and app/ and restarted. Reinstalled QTR and printer and the problem persists.

Any advice?

For now I am assuming that files like the one below (from Paul Roark) let me print an untagged grayscale file as if I was using calibration mode. Am I right?

PRINTER=Quad1400-Eb
CURVE_NAME=K-0-100
GRAPH_CURVE=YES

N_OF_INKS=6

DEFAULT_INK_LIMIT=100
BOOST_K=
LIMIT_K=
LIMIT_C=
LIMIT_M=
LIMIT_Y=
LIMIT_LC=
LIMIT_LM=

N_OF_GRAY_PARTS=0
GRAY_HIGHLIGHT=0
GRAY_SHADOW=0
GRAY_OVERLAP=
GRAY_GAMMA=1
GRAY_CURVE=

N_OF_TONER_PARTS=0
TONER_HIGHLIGHT=10
TONER_SHADOW=10
TONER_GAMMA=1
TONER_CURVE=

N_OF_TONER_2_PARTS=0
TONER_2_HIGHLIGHT=10
TONER_2_SHADOW=10
TONER_2_GAMMA=1
TONER_2_CURVE=

N_OF_UNUSED=5
UNUSED_INK_1=C
UNUSED_INK_2=M
UNUSED_INK_3=Y
UNUSED_INK_4=LC
UNUSED_INK_5=LM

CURVE_K="0;0 100;100 "

Thank you,

Vincent

The calibration mode is very sensitive to Color Management interfering.
 This is tricky to avoid in OSX and PS
these days.  The curve you show gives a similar straight-line of one ink.
 Mostly this will work but CM again
may interfere and put a little curve in it -- (not nearly as bad as the
calib mode).  You probably can get away with it.

But it you want exact no color management I have a new program called
Print-Tool that allows control over
color management. This is a whole new and separate application -- not
completely necessary but makes things
a lot more convenient.

I have been using the QTR Print Tool for several months and the control over color management, tricky at best with MAC and OSX and Photoshop, has great simplified my life and made it much easier to retain consistency in my work with digital negatives and in printing monochrome prints with Jon Cone's K7 inks.

Depending on the specific OSX system and Photoshop I found some work-arounds for the absence of No Color Management, but none of them proved 100% reliable. So if you work on a MAC and use Photoshop and need to work with No Color Management the QTR Print Tool is a piece of software you really need to own.
