changing one color to another

Not knowing how you have your document set up nor what your drawing is composed of, this should get you close.

Assuming each 1 fill color per object

It maybe have about 4-5 different colors in it, but om many many small places.

Click to expand...

Open the object manager - Window -> Dockers -> Object Manager. (this is version 10 specific as that's what's on the machine I'm in front of right now)

You should see at least a Master Page and Page 1 listed.

Under Page 1 there should be a plus sign next to Layer 1.

Click the plus sign to expand it.

You should see all the objects in the layer grouped by object type (or shape). Their fill color is also displayed.

You can [ctrl] click or [shift] click to select multiple groups of objects (in this case by fill color). Once you have all your objects selected just edit the fill properties to change the fill to a different color.

Hi there.

I don't think you have to change every objects color.

Simply send it to the printer and Corel will calculate the CMYK % for you.
