Well AFTER the printers are calibrated by the PhaserMatch software I¹m
using a device link to ³simulate² ISOCoatedv2 on the printers.
Would this be the CMYK profile I would use in the ColorSync utility?
But since I send the 140 Patch Chart CMYK TIF file to the printer during the
PhaserMatch calibration procedure with the driver settings set to NONE (no
color management) - aren¹t the cmyk, lab value pairs that you described
PhaserMatch using to make the transforms different than the cmyk, lab values
I will obtain using a profile like ISOCoated v2 in ColorSync utility?
Or should I be using a ICC profile for the Phaser printer (Media Type/PQ
setting) that I¹m calibrating for?

Yes I can see that it¹s a bit of a process but thanks it does look like
it will provide me with more precise Lab values.
