[argyllcms] Targen query

Why is it that the targets produced by targen perceptually look - at least on my printouts - as though they're made up mostly of quite saturated color patches, even though the algorithm is distributing the patches evenly in device space? i.e. there don't seem to be all that many 'greyish' subtle colors, either light or dark.

I double checked the distribution of rgb values in the ti1 file and that was all in order.

It raises the question in my mind about what 'gamma curves' are used by printer manufacturers in their devices, i.e. if the printer's raw behaviour is perceptually non-linear, and targen is spreading patches with a linear distribution in device space, then I guess the saturated colors might well be over-represented. I suppose this is the reason for the -c switch in targen. (Is it therefore also necessary to select a -f suboption that spreads the samples in perceptual space rather than device space? Presumably it would not know how to do this unless it had been given a starting-point profile to work off with -c?)

I know...I ask too many questions...

Cheers.,
Milt
