graphs?

Yes - sort of.  I derived the lab L from the X-rite 810 visual density
readings using: d=-log(Y) and Y=((L+16)/116)^3

Yes, I set the gamma in OPM to 2.2 - except when I forget.  Jobs
sounds like a good idea :)

My monitor is hardware calibrated to 2.2 and my working space is gamma
2.2.  I leave the files untagged and use a custom dot gain for soft
proofing.  I make all the changes to the file while it's in the
working space, save it as a master, duplicate it, apply the soft proof
and make one more layer adjustment until it matches the master.  I
print it with OPM and a gamma of 2.2 and then make any little local
adjustments based on what the print looks like not the screen.


It may be a little cumbersome but it seems to work well.

If there was a shortcut to go directly from the working space ( and
the master file )to the print that would be cool.  I haven't figured
out a way to do that.
