Dear Ben,
I'm building an output CMYK profile, I've also realized an input profile for my
flatbed scanner used as poor man colorimeter, this kind of workflow requires a
lot of editing of the acquired target. For that reason I'm asking if someone
had a similar experience and wants to share it.

Wait -- this is an input profile?
You don't want to edit a chart image before feeding it to a profiling engine.
At least, not unless you're going to be performing the same edits to every
image as part of your standard workflow.
If the capture device isn't behaving well, you might not get a good
profile...but it's the job of the profiling engine to compensate for the
device's misbehavior.

Dear Ruggero,
my target is only two months old and is in good conditions, the scanner
profile is coherent (althougt lack a bit of contrast). Maybe the problem is
caused by the fact that my target are printed on a 10mm thick support not on
paper I cover the scanner with black fabric and turn off the light
but...maybe isn't enought. Another problem could be the fact that the support
is far from paper white point ( approx. 87-0-5 in Lab values).
I know I'm working far from good practice but I've only this instrument so
far.
Thank everyone
Best regards

Is your IT8 target bad or discolored?
It could be the reason why you’re not getting correct colors *and* have to
edit in Photoshop.

Subject: [argyllcms] Editing profile
Hi everyone,
I'm realising some CMYK printer profile using a scanner. As wrote in the
documentation profiles have bad exposure and a quite strong color cast.
I finally reach some decent result correcting (by trial and error) with
photoshop the .tif file of the scanned target but sometimes I get some
errors if the correction is too strong (...I think).
Is there a more proper way in editing profile using some freeware or quite
cheap programs or is possible to properly edit the numerical value measured
in the .ti2 or .ti3 to get a better result?
Thanks to everyone
Best regards
