About spot and process color types


    You can designate colors as either spot or process color types, which correspond to the two main ink types used in commercial printing.

    You must create spot colors as named swatches stored in the Swatches palette, so that you and your prepress service provider can uniquely identify each resulting spot color printing plate. In comparison, printing any process color requires no more than four inks, so you can use process colors either as swatches or as unnamed colors.
