> can you tell me whats the difference between rgb and cmyk mode?

RGB mode is display color, or color created by light process (like a
monitor, TV, LED prints) and CMYK is generally printed color based on
light absorption (inkjet, laser and offset printing). RGB can display
more color; CMYK is a smaller color space. Light is more efficient
than aborbtion...the latter has to account for media, ink/toner,
paper and the loss in efficiency is really insurmountable. The
difference between the two is something like shining a flashlight
directly into your eyes and reflecting it off a wall: No matter what,
the reflected light will not be as bright.


This is really a frequently asked question. You might try looking at
http://groups.yahoo.com/group/ps6/message/603 and the link there as
well.

Hope that helps!
