Spot color printing in offset printing refers to the colors that are generated by an ink, whether pure or mixed, that is printed through a single run. The widely spread off-set printing-process consists of four spot colors: Cyan, Magenta, Yellow and Key (black) which is referred to as CMYK. The advanced processes involve the use of the six spot colors, which is the hexachromatic process), and then add two more colors – Orange and Green – to the process thus, the term CMYKOG. Orange and Green are added to compensate for the inefficient reproduction of faint tints that use the CMYK colors only.

Technicians all over the globe use the term “spot color” when pertaining to the colors that come from the non-standard offset ink. Sometimes these are metallic, spot varnish, fluorescent or custom hand-mixed inks. When making multi-color prints with the spot color process, every spot color needs a lithographic film. The areas of the same color when printed use the same film, so the six colors all come with a lithographic plate.

The dot gain, along with the screen angle and the line frequency, refers to the spot color that varies, depending on the very purpose of the process. If the spot printing requires lamination and UV coatings, then these are referred to as the spot colors. As all these share the characteristics of requiring the process to separate the lithographic firm and the print run, then it all boils down to the whole hexachromatic process.
