2 questions for colors
1) Does ConTeXt offer complete color gestion as pdf spec 1.6 or there
are some features not implemented ?
2) Preparing a pdf with bitmap colored images for offset press (ie
covers for manuals): are png or jpeg an optimal solution or tiff is
better ? RGB or CMYK ?
Thanks in advance

what do you need ... process- and spotcolors are implemented, as are
duotones; transparency has been around for years now.

normally an unscaled cmyk jpeg of medium compression quality is ok (a
24 meg tiff graphic is not per definition better than a 4 meg jpeg image)
