Ganging affects system calculations primarily by (but not exclusively) reducing the makereadies, inks and stock down to what is required by a single press sheet and then dividing the cost among the individual components or jobs based on the percentage allotted.
In the case of Prepress; costs of the specific process will be divided amongst the components based on the percentage calculated by the number up.
For Postpress; calculations of the cost of makereadies of the specific process will be divide amongst the components and the run of the process will be calculated normal based on calculation method and the number up within each process.
In both case, the processes that will be included in the gang run will need to be identified by selecting the "Include in Gang Run" checkbox.
