when we have to deal with dealing with professional printing png is a 
no-go and only jpeg compression (lossy) and tiff compression (lossless) 
make sense; pdftex only supports jpeg inclusion natively, so in the case 
of screen dumps, the other alternative is to save as tiff and convert 
that to cmyk (in an editor) and then pdf before inclusion (actually, we 
always convert to be included images to pdf first, mainly because 
inclusion of pdf is much faster)

interesting; buy why no rgb -> cmyk conversion; i'll give it a try 
anyway -)
