Digital printing is similar to the process used by your inkjet desktop printer, which makes use of mulitple printheads laying down various colours pass by pass, either at the same time or at different time depending on where the colour is required in the print.
There are other printing processes used in the advertising world. Namely litho and silk screen printing, which main benefits are low costs on very large quantities. These processes get costlier the more colours you use. An example of litho printing would be newspapers and silk screen printing would be used for t-shirts.
