I don't even know how to reply to this... color mangement is a voluminous subject! You need to read about color calibrating, a good start is use "search" on this site and read the posts. But there are great primers out there on this, some a bit too technical for my taste. David Milsock who contributes his input in many of the posts on this Corel site - I understand has written a book on this subject, specifically with the Corel user in mind. Perhaps you can contact him?

So in short, there's more to just changing a color pallet to accurately print on a press. Hope this points you in a direction.

If you use a CMYK palette to assign color to your objects, those are the colors that the press will print. CorelDRAW doesn't change CMYK color values while printing. CMYK images too, Corel doesn't change its values while printing. This is why it is good to correct image reading ink value.

Now if you want to simulate press printing in your screen, you could get a good approximation, but it is impossible to simulate cyan chromatic or yellow as riches as they print.

That was probably the easiest response... naturally would think if the design was intended for print the user would be selecting a CMYK palette. However, as you infer, there's much more to trying to find a fit between a monitor and paper/ink. I use Monaco Ezcolor on my XP system, which has provided me a reasonable relationship between monitor, scanner, in-house printer. Pantone is selling a new product called the ColorMunki (spectrophotometer) that will calibrate your monitor/printer and allow mobile color capture for designers/photographers.

After you calibrate buy some Pantone process and or spot color guides and build your file accordingly.
