Wiring Up

Step-and-repeat—The software should be able to automatically copy and place copies of an image (such as a label) to fill a sheet or plate following parameters set by the software operator. The term "imposition" is sometimes used to refer to the same functionality.

Trapping—The software should enable the operator to check areas of an image where colors overlap or meet and to adjust the trap as needed. This is manual (also known as interactive) trapping. In automatic trapping the software does all the checking and makes changes on its own. Most software offers both, allowing operators to use automatic trapping and check the traps later to make delicate adjustments as needed.
