3.3.1. Exception table

The exception table is a collection of exceptions to the default rule for determining the order of signatures (nC+I+C).

It should be noted that impositions made by the program based on the general rule are technically correct. Using the exception table allows for even better planning of the size and order of signatures in very specific situations.

To enable the exception feature, select the Enable exception table check box.

Adding, editing, and deleting entries in the Exceptions table is done by selecting the appropriate command from the context menu available after pressing the right mouse button.



When calculating the signature order, the program checks the exception table for definitions corresponding to the number of pages in the signature and the number of pages in incomplete signatures.

Entries in the exception table that meet these conditions are displayed in black, while entries that do not meet the conditions are displayed in gray. If the program finds a suitable exception, it will apply it automatically, provided that the YES value appears in the last column labeled Active



Only one exception that meets the condition for the number of pages in the signature and the number of pages in incomplete signatures can have the active status (status in the Active column = YES).

Enabling the Active exception switch in the Define exceptions dialog box (also available when editing an exception) will automatically disable other exceptions that meet the conditions. Disabling an exception will not enable other exceptions.


The exception applied is given as the default signature order and marked in green in the Exceptions table.

The U column should contain the number of pages in the incomplete signature(s), and the C column should contain the number of pages in the complete signature.

When editing an exception, the minimum number of pages in a signature is 8, because a 4-page signature has no incomplete signatures and therefore no exceptions.

When editing entries in the exception table, remember that the entry must always contain the phrase nC (case sensitive) indicating the group of complete signatures. In the Sequence column, the sum of pages on incomplete/overcomplete signatures must be equal to the value in the I column or the sum of the values in the I column and the number of pages in the signature (I +C).

Important! When an active exception is saved in a project or template, the program adds it to the Exception Table when the project is reloaded, if it is not already there.

All other exceptions are deactivated.

If no exceptions were active when the project or template was saved, the Exception Table remains unchanged.

Imposition doesn’t have to be difficult!
