Using spot and process colors together

Sometimes it's practical to print process and spot inks on the same job. For example, you might use one spot ink to print the exact color of a company logo on the same pages of an annual report where photographs are reproduced using process color. You can also use a spot color printing plate to apply a varnish over areas of a process color job. In both cases, your print job would use a total of five inks--four process inks and one spot ink or varnish.

Important: If an object contains spot colors and overlaps another object containing transparency features, undesirable results may occur when exporting to EPS format, when converting spot colors to process colors using the Print dialog box, or when creating color separations in an application other than Illustrator. To prevent problems in these cases, you should first convert the spot colors to process colors.
