Bookbinding system with controlled trimming unit

A bookbinding system comprising:

• a folding unit configured to perform a folding processing on a sheet bundle comprising a plurality of sheets;
• a trimming unit configured to perform a trimming processing for trimming an end of the sheet bundle on which the folding processing is performed;
• a setting unit configured to set a trimming amount of the trimming processing based on a input of a user;
• a comparing unit configured to compare the trimming amount set by the setting unit with a shift amount between an inner sheet and an outer sheet of the folded sheet bundle occurring at an edge of the folded sheet bundle;
• and
• a control unit configured to control whether or not to cause the trimming unit to perform the trimming processing based on the set trimming amount, based on a comparison result of the comparing unit.

A bookbinding method comprising:

• a folding step of performing a folding processing on a sheet bundle comprising a plurality of sheets;
• a trimming step of performing a trimming processing for trimming an end of the sheet bundle on which the folding processing is performed;
• a setting step of setting a trimming amount of the trimming processing based on a input of a user;
• and
• a control step of inhibiting, when a shift amount between an inner sheet and an outer sheet of the folded sheet bundle occurring at an edge of the folded sheet bundle is greater than the trimming amount set at the setting step, performing the trimming processing based on the set trimming amount at the trimming step, and to allow, when the shift amount is not greater than the set trimming amount, performing the trimming processing based on the set trimming amount at the trimming step.
