2 questions for colors 1) Does ConTeXt offer complete color gestion as pdf spec 1.6 or there are some features not implemented ?

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

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 ?

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) 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 -----------------------------------------------------------------
