Sorry for imprecise question. I meant black generation in rgb images in JPG format included in document. If it's not possible to control the amount of black in that case I'd like to use cmyk JPG images, but will they be left untouched by the colour conversion mechanism?
AFAIK ConTeXt doesn't touch pixel images at all - that would be a rather complicated task, perhaps using little_cms or GIMP libraries or the like...
indeed, however, you may expect some manipulations without touching the bitmap, like runtime turning gray scales into spot colors and duotones; i have something running here for half a year now but i recently moved the code into the kernel

Right, but what exactly happens with included rgb bitmaps when I use:
\setupcolors[state=start,cmyk=yes,rgb=no]
Will they be left in rgb?
bitmaps will not be touched by context, so they will stay rgb (i'm currently cleaning up some figure postprocessign code, so meybe that end up in the distribution) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
