Before you begin this procedure, be sure your publication is set up for the type of commercial printing you want.
How?
On the Tools menu, point to Commercial Printing Tools, and then click on Color Printing.
In the Color Printing dialog box, select the options you want.
Note If your publication contains a CMYK-separated picture, such as a TIFF, and the publication is set up for spot-color, Microsoft Publisher prints the picture in grayscale on the black plate.
