Press sheets can be backed up if one of the following criteria is met:

• Perfector is used as the work style.
• The image is not centered on the plate, for example, if you are using a larger plate size than needed.
• Different size press sheets are used.

Given the above criteria, the plates will not back up if you try to back up plates instead of press sheets.
