| Offset Printing eliminates many of the mechanical | | | | Pre-Press |
| steps required for litho-offset printing (see below), | | | | The procedures and processes digital files must go |

| DPI (Dots Per Inch) | | | | Trim Size |
| DPI is short for Dots Per Inch. It is a measurement of | | | | This is the final size of a document after excess |
