Test strips typically contain a small set of wedges for each colorant (ie. 0%, 25%, 50%, 100%), + some composite black (ie. CMY and CMYK) test wedges to judge grey balance. You might be able to use targen for much of this, and/or add values to the .ti1 in by hand. You can use icclu to get the rough XYZ values in the file. Graeme Gill.
