Thank you Dana!
Ok, the numbers for printer 2 (the one I am happy with the results) are : 15.56,22.73,40.39,87.26,32.34,63.71,79.51
the numbers for printer 1 are 15.67,23.77,40.37,86.87,30.96,67.51,80.73
I see a big difference in ink 7 (light black) of delta e 3.9 - the big difference in that channel starts at 45% all the way to 100%
can you work with the above numbers or do you need additional information from me ?
thank you very much
