If you have measured datas then averaging is quite simple.
If you have no measured datas, you still can perform profile averaging but
it rather long process.
You should have:
1.Profile building software (not exatcly the same which was used during your
profile creation. Lets say you have PrintOpen).
2.LogoColorLab.
3. MS Excel.
4.1-2 hours.
Also you shoul know that this process is not very sharp. I've made profile
recreation by such method(I had PrintOpen-created CMYK profile but I've
needed ColorBlind-created Profile). Averaged delta E was 0.8, Maximum delta
E was 5 (I've used PrintOpen 210-patch form for delta E calculations).
Method:
It looks like extrapolating measurement datas of target Profile building
software by converting it's CMYK testform (not TIFF but ASCII text file with
CMYK values only!!!) in ColorLab from both profiles into LAB. So you'll get
two files with measurements you need to average and create averaged profile.
Then you need only edit this files in order to make them 'understandable' by
your Profile building software. I'm making it in Excel. Then you can average
them and create new profile with TIC, GCR/UCR etc. as you like.
