Hi David  and Ping


I'm so sorry to haven't  strike the right note, I 'm interested in the
principle or arithmetic which is used by Photoshop to convert RGB image to
CMYK (and CMYK to RGB).


Does anyone know the arithmetic of converting RGB to CMYK?
or, does anyone have any recommendations ?




Thanks in advance for any help given.
