Which M to choose in i1Profiler today
« on: August 24, 2016, 07:49:38 pm »

I need to do some profiling for a new 3880. I have done nothing but B&W for a couple of years now so thought that I would ask about the state of play with i1P today.

First thing that I notice is that I can no longer save profiles at System Level. I can't find any Preferences, and I am an admin. Any suggestions?

It now appears that I can scan at M0, M1 and M2 and that the output files are different so I should get different profiles using the different measurements. Is there an Xrite gotcha hidden in there, or can I simply go ahead and use M2 for IGFS and M0 for non-OBA matte papers.

X-Rite published a paper on their website carrying a good discussion of the "M" factor. You will find it here:"M" factor - what does it mean. This should address all your questions about which to use under what conditions.

Thanks Mark. I understand the concept only too well. What I am asking is the state of play with i1P today. I have been caught in the past by what i1P is supposed to do and reality. As an example, in an earlier version M0,M1 and M2 all produced the same measurements.

My preliminary work is suggesting that my new profile is a smaller gamut than my profiles produced a while back, hence the question.

The measurements look very close but the profiles behave differently, and yes, there are gamut differences between them, but tends to be small. For example if you are using a paper containing an OBA and you make an M1 and an M2 profile, the M2 may have a slightly smaller gamut than the M1. In terms of profiling accuracy, which to my mind is a bigger deal than small differences of gamut, it is best to select the correct "M" relative to the paper at hand - does make some difference.

Thanks Mark. So there are no hidden gotchas with Xrite profiling in the latest version? Any idea of how to get System Level saving?

Capture all, build a profile from each, pick the one you prefer. Also see: https://luminous-landscape.com/eye-one-pro-ii/

To say that there are no hidden gotchas in this poorly documented piece of software with its dreadful GUI and sometimes buggy behaviour would be hanging out on quite a thin limb. But I'm confident in what I have advised so far! :-) I do have access to System Level saving using the latest version of i1Profiler in "Advanced" Mode (a tiny radio button on the far right of the Home screen, about mid-way down) on Mac OS El Capitan.

I know what you mean about thin limbs. I am on El Cap 10.11.6 and Advanced but System Level is not selectable. that changed at some update along the way. I can live with that minor inconvenience.

I could never expect more than what you have advised, thanks again.

I just solved the System Level. Apple had changed the Profiles folder permissions along the way. At least that was easy.

Ah yes - I remember now. :-)

Thanks for the reminder. These companies just sneak stuff into their upgrades, and go figure where to know about it. What a minefield.
