Training module Apogee Prepress 8.0

About this training module

In this training module you learn how Trapping works in Agfa Apogee Prepress.

What is Trapping?

Trapping is a prepress procedure that obscures potential register errors between different color separations.
These register errors can be caused by paper shifting, environmental variables, presses or plates that are out of register, etc.
To obscure the errors, the trapper creates small overlaps where the different colors meet.
