The BookFormat ScriptLine contains the properties that represent the fact that a Script will eventually become a printed diary, or book. There is only one BookFormat ScriptLine per Script, and it cannot be deleted, moved, nor disabled.
If the values of these 2 properties are equal, then that number is displayed alone (as shown above on the left). If the two values differ, then both are displayed with the number of defined pages appearing first (as shown above right).
Some of this ScriptLine's properties have a direct impact on the output file (Signatures, Physical Sections, Size, Size Units) while others (Binding Style, Job #, Spine Orientation) are used to help classify Scripts in view of the integration of Q++Studio with an imposition or production planning software.
