Re: [QuadtoneRIP] QTR calibration stopped working with latest OS X update; work around?

2013-06-14 by Roy Harrington

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.
