[NTG-context] Colors and images Context

2006-03-16 Thread luigi scarso
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
luigi

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)
