Hi, I am trying to create chart for RGB printer calibration. I run targen with these options: targen -v -d2 -s52 -e3 -f0 linearization-target The resulting chart contains RGB values of CMY color shades. I was expecting to see color shades of red, green and blue. Is it a bug in targen, or do I miss something? Cheers Radek First ten patches: NUMBER_OF_FIELDS 7 BEGIN_DATA_FORMAT SAMPLE_ID RGB_R RGB_G RGB_B XYZ_X XYZ_Y XYZ_Z END_DATA_FORMAT NUMBER_OF_SETS 156 BEGIN_DATA 1 100.00 100.00 100.00 95.106 100.00 108.84 2 100.00 100.00 100.00 95.106 100.00 108.84 3 100.00 100.00 100.00 95.106 100.00 108.84 4 98.039 100.00 100.00 93.309 99.073 108.76 5 96.078 100.00 100.00 91.558 98.171 108.68 6 94.118 100.00 100.00 89.854 97.292 108.60 7 92.157 100.00 100.00 88.197 96.437 108.52 8 90.196 100.00 100.00 86.585 95.606 108.44 9 88.235 100.00 100.00 85.019 94.799 108.37 10 86.275 100.00 100.00 83.498 94.015 108.30 ...
