Auto Impose Rules Overview
The Auto Impose Rules dialog box lists all available Auto Impose Rules resources in the left column with their settings in the right column.
Name
A meaningful name of the rule, e.g. Lowest folio on Back, Magazine jobs
Selecting Fold Sheets
The priority and strictness of the placement rules can be set here. Priority can be set for rules with the same strictness, by moving the rules up and down in the Rule table. The following rules are possible:
•Largest fold sheet: instruction to use the largest possible Fold Sheet, i.e. the one with the most pages. The strictness setting is always Prefer but you can control this priority by moving the rule in the list.
•Align lays: instruction to place a Fold Sheet so that its lay is in the same corner as the Press Sheet lay. Default strictness setting is Must be met. This rule ensures that the distance between the Fold Sheet and the edge of the Press Sheet is constant.
NOTE: This rule is ignored when the alternative workstyles Work & Turn and Work & Tumble are applied.
•Lowest folio: instruction to put the lowest folio on the Front or Back of a Press Sheet. The default strictness setting is Do not consider that puts the front of the Fold Sheet on the front of the Press Sheet. This rule only applies for the Sheetwise or Perfecting workstyle. Apply to cover sheets only can also be selected for this rule.
•Maximize page count: instruction to search for alternative arrangements using multiple, smaller Fold Sheets to reduce paper waste. Default strictness setting is Do not consider while Must be met cannot be selected. This rule also includes a check box to set the Maximum number of extra cuts to avoid complex layouts with too many extra cuts.
•Stitchable Fold Sheets: a built-in rule for nested assemblies that ensures that the resulting Fold Sheet can be stitched, e.g. an F8-2 is stitchable while an F8-5 is not.
•Single leaf (F2-1): a built-in rule to avoid the F2-1 Folding Scheme whenever possible; this scheme is only used when 2 pages are left or when required for the given Press Sheet Size.
NOTE: The latter 2 rules are not visible and cannot be switched off.
Placing Fold Sheets
Select the Single-row schemes: Arrange according to Page Arrangement check box to have covers and irregular single-row schemes arranged according to the head and foot Page Arrangement settings of the Binding Options.
Alternative workstyle
This setting instructs Apogee Impose to use a different workstyle than the default Sheetwise workstyle when printing several Folding Sheets on a single Press Sheet, e.g. to print a cover or to print partial book signatures on a larger Press Sheet.
If possible, print N-up or partial signature using
Select this option to print multiple Fold Sheets using an alternative workstyle. By default this is not selected and Press Sheets are printed using the Sheetwise workstyle. The two alternative workstyles are:
•Work & Turn
•Work & Tumble
N-up means that the alternative workstyle is applied in the following cases:
•if the same book signature can be used an even number of times
•if different book signatures can all be used an even number of times
NOTE: Alternative workstyles are never applied for printing on a perfector press.
Assembly
These settings deal with the order of the book signatures in the Product assembly and whether partial signatures must be handled differently.
Book signature order
book signatures can be ordered in the assembly in two ways:
•Largest first: If a Product consists of book signatures of different sizes, Apogee Impose sorts them in descending order with the largest in front and the smallest at the end.
•Smallest first: Apogee Impose sorts book signatures in ascending order with the smallest in front and the largest at the end.
NOTE: The Parts of a Product also determine the order of book signatures and have precedence over the Assembly settings here. In other words, a Cover book signature is always placed before Body book signatures in the assembly.
Partial book signatures
Partial signatures are book signatures that have fewer pages than the largest book signature in the assembly. Ideally, an assembly must have full book signatures at both edges and partial signatures in between. Select the Keep away from edge by check box and enter the number of full book signatures that must be between the front or end and the partial signature.
