Assembly Pane
The Assembly pane shows how the different book signatures (BS), i.e. folded Fold Sheets, of the product are put together. In this pane you can define and arrange book signatures to suit production needs.
The Assembly displays the book signatures of a Product (BS1, BS2, etc.)with a name that corresponds with the respective Fold Sheet (FS1, FS2, etc.). These names are generated automatically together with the number of pages, and the start and end page of the book signature. A color code is used to indicate book signatures of the same Part, e.g. orange for Cover and light yellow for Body parts. Special color codes are used for certain kinds of jobs, e.g. JDF jobs.
Apogee Impose automatically creates separate book signatures for the different Parts of a Product.
1 Cover book signature (BS1)
2 Body book signatures (BS1 and BS2
3 Number of pages per book signature
4 Start and end page numbers of the book signature
Assembly Types
There are two main assembly types and a mixed type:
Nested for saddle-stitched products
Stacked for perfect-bound products
Mixed: a combination of nested and stacked products
