Sorry, but you can indeed make a profile from a single press sheet, if
you know the press sheet represents your target condition for the
printing process.
This discussion goes back to the Volume 1 of the Digest in which
Matthias Nymann pointed out that the question is not how many sheets
you average but how well you control your process.
You can profile a process from one sheet with Eye-One Pro / Eye-One
Match or from one hundred sheets with iCColor / ProfileMaker, but the
bottom line is the process control.
As this is a US list, and as folks in the US are fond of SWOP, it may
be worth bringing to attention that the SWOP process was not
characterized using a sizeable statistical sampling set. It was
characterized using a miniscule statistical sampling set.
Don't get me wrong, the first post on ColorLab dates from 1998, before
it became the MeasureTool and the MeasureTool made it to the US, but
there needs to be a concept that ICC color management is not a panacea.
The profile is only as good as the process, averaging or no averaging.
Thanks,
Henrik
