[pdftex] RGB image in pdf inteded for printing.

[John Culleton]

If I use a colored graphic in e.g., png format and the color model is RGB how 
does pdftex handle the color model question?  Some printers require CMYK 
model for everything. 

Another question:
I know about converting color model via ImageMagick prior to inclusion but 
what then is the preferred output format? Tiff is not an option of course.
