I've borrowed a Gretag Digital Colorchecker SG in order to profile my scanner (epson V700, Vuescan, 'raw' tiff output). Seems to work quite nicely, building profiles with PM5 and the generic reference file that it uses.
I want to build a reference file for this specific Colorchecker so using my Spyder3Print Spectrowhatsit I've taken Lab measurements from each patch on the target. 5 measurements per patch, so I can average them.
I'm stumped with the next step: how do I turn my little .txt file into a reference file that PM5 will recognize? (maybe something Argyll can deal with?)
And: have I captured enough data to do it? is my data good enough?
Have to give the target back later tomorrow morning, so the data I've got is it, for now. this is a clip of what it looks like:
1 96.76 -0.27 3.60
2 96.62 -0.45 3.59
3 96.80 -0.37 3.51
4 96.78 -0.47 3.54
5 96.64 -0.60 3.55
6 8.72 -0.45 -0.60
7 8.60 -1.12 -0.81
8 8.60 -1.12 -0.81
9 8.62 -1.18 -0.78
10 8.60 -1.12 -0.79
1-5 being patch A1
6-10 being patch A2, etc.
