I fear that I have found a Catch 22 when trying to create a good printer profile (using Argyll, Ubuntu Studio, Epson XP-960).
I am following the steps outlined in https://www.ludd.ltu.se/~torger/photography/argyll-print.html, and it seems to work all right (except for the fact that Argyll cannot handle a 6-ink printer yet) – until I start thinking about Step 4: Print the test target page.
How on earth do I print a proper target when I (under Linux) am unable to “disable any color management”? That must mean that my test print is “contaminated” already from start? Or?
Please, what have I overlooked?
