[Openicc] Gutenprint team requests CM-off for a print queue be provided as a maintained engineering facility.

[Max Derhak]

Why does the option need to be named "Turn off color management"?  Why don't we have an toggle between "Normal Printing" and "Printer Profiling ".  To the neophyte user this is obvious when  they aren't profiling the printer.  The fact that it turns off color management is in the background and is much less confusing.

Richard, at LGM we had a conversation where you said you wanted CM to be as simple as possible for most people and I said that was fine as long as the simplicity did not prevent people who needed higher quality from doing their work.

Not being able to switch off colour management on a given queue means not being able to profile the device on that queue, so seems to fall into that category.

Imagine if there was manadatory full-screen colour management and the colorhug had to measure a screen and then find the profile that was used and try to undo what it did, to get a measurement ...

Exactly.

Or it means that inaccurate profiles will be made because the patches were generated and printed incorrectly.

This is well put.

If the concern is confusing users, then (on a GUI) hide it in 'advanced options' or guide them with 'you will not normally need this, unless you are profiling the printer'.
