Hello again I have created some ramps for the C M Y colorants. I have created them like this: $printtarg -v -e -ii1 -r -pA4 cyan I need to get the resulting ti3 file into Lab format to feed a very nice spreadsheet Hal V. Engel have created. When I run spec2cie with any options I get the following error. $ spec2cie -f cyan.ti3 cyan-lab.ti3 Unknown: Error - Device has unhandled color representation 'C_XYZ' Is it not possible to do this or have I created my ramp wrong.
