The invention relates to a method for producing collections (15) from a plurality of N (N=2, 3, 4, . . . ) different printed products (11a-d), which collections (15) each comprise a stack (13) of printed products (11a-c), which stack is packed in a packaging element (11d) wrapped around the stack (13). A solution that does not require additional material use includes the following steps: providing the N printed products (11a-d): forming an intermediate stack (13) from Nx (x=1, 2, 3, . . . ) of the N printed products (10a-d); providing the x remaining printed products as a packaging element (11d); and wrapping the intermediate stack (13) in the packaging element (11d).

An image forming apparatus includes: a first apparatus configured to perform punching on a sheet by using a punching member; a second apparatus, including a stacking part on which a plurality of sheets punched by the first apparatus is stacked, and configured to perform binding so as to obtain a bookbinding article in which a binding member penetrates in a ring shape through punched holes of the plurality of sheets; a notification unit notifying information; and a control unit configured, in a case of starting a job using the first apparatus and the second apparatus and determining that a jam has occurred in the stacking part, to cancel the job, and to cause the notification unit to notify that a thickness of a sheet stack stacked on the stacking part exceeds a thickness that enables to be bound by the binding member used by the second apparatus.

A printing control apparatus according to one aspect of this invention controls to print images on sheets based on image data of a plurality of pages, generate a bookbinding product by executing folding processing for the image-printed sheets, and output the bookbinding product. The printing control apparatus further accepts the position of an insertion sheet to be inserted into the sheets for which the folding processing is executed, and controls to output a plurality of bookbinding products by using, as a reference, the accepted position of the insertion sheet.

[Problem] With a simple configuration, bookbinding can be performed such that a document sheet can be identified for each chapter by an index sheet, and a predetermined sheet can be easily turned over and opened.

[Solution] A post-processing apparatus adapted to cause a document sheet S1 having a document formed thereon and an index sheet S2 having a chapter title formed thereon to overlap each other, and to perform bookbinding such that the document sheet S1 is identifiable for each chapter by the index sheet S2, the post-processing apparatus including: an image formation unit configured to form, based on a title setting function provided in document generation software, the chapter title on the index sheet S2 according to chapter title information attached to the document; a processing formation unit 30 configured to form a cut-out or cuttable portion-to-be-processed K on the document sheet S1; and a bookbinding unit 40 configured to cause the document sheet S1 having the portion-to-be-processed K formed thereon and the index sheet S2 having the chapter title formed thereon to overlap each other such that the document sheet S1 is positioned on the index sheet S2, and to perform the bookbinding by causing the portion-to-be-processed K of the document sheet S1 and the chapter title of the index sheet S2 to coincide with each other.
