Because both the screenshot from old thread I mentioned (http://digitalproof.info/argyll/black_gen/xicclu_-g_-fb_-ir_SC_paper_bas.pn g) and the results I get from other softwares showed the same for the rel. intent (PM_rel and CO_rel attached) and what I get from xicclu seems to match the perceptual (PM_perc and CO_perc attached).
I'm pretty confident xicclu is doing what it should. Please note that the graphs don't cover the same range though. The xicclu graph range is from white point to black point (to help in setting the black generation parameters), whereas the other graphs you are showing, cover L* 100 to 0. (It's unclear to me what intent the other graphs are for. None of the dialogs seem to show the intent chosen.) Graeme Gill.
