In JDF, the finishing operations like punch, fold and staple are applied on the trailing edge (left) of the job, or the top left corner of the trailing edge (top left). To set the finishing operations on other edges, the input of a finishing process must be transformed. Transformations are applied as follows:
Rotate the media sheet counter clockwise.
If Flip is specified, flip the media sheet upside down. After this rotation, the top edge is on the bottom and the back side is on the front.
Apply finishing on the new left edge, or the new top left corner, after the transformation.
The media sheet is always considered as portrait-oriented, i.e the left edge is always the long edge, regardless of the orientation of the content.
