I have 2x24 values: Those resulting from a scan of an original colorchecker, and those of the scan of the printout. The difference between these values should allow some kind of correction function to be applied. I know that I cannot get all parameters that are to be handled by a profile. I was wondering if there are routines to generate this matching table in the form of a simplified profile included in argyll. I have been using a similar approach for color correction with the tool macbethcal, which is part of the radiance light simulation distribution (radsite.lbl.gov). This also just created a simple correction function. The problem is that it works only on tiffs and not from inside applications, so I would have to establish an export-correct-print workflow for everything. Maybe I am completely wrong? Thank You for all the information... Lars.
