[comp.graphics] Color seperation of 16 bit Targa to CYMK and 24 bit RGB to CYMK.

Hi, 

I'm looking for an established method to convert a 512 X 480 X 16 bit RGB
image to it's CYMK components for rendering on a output device. I'm sure
the information is out there but where ?

Also I would like to be able to scale the image up to fit a full page
at 8 X 11 200-300 dpi. So it looks like I need about four steps.

1. Scale the image to the appropriate size.

2. convert every RGB component to CYMK components

3. use gamma corrected Dithering patterns that map to the CYMK values
   to create my output data.

4. send output to device.

Assuming that the above is straight forward, converting 24 bit RGB to CYMK
and then following the same steps would also allow me to render it.

Any help would be appreciated!
