Use the Mark Rules Editor to create the rules for adding marks to autocreated and autoganged layouts.

1. Perform one of the following actions:
   • Select Resources > Mark Rules Editor.
   • In the Utilities folder, double-click the PrepsMarkRulesEditor file to start the software.
2. In Mark Rules Editor:
   • In Mac OS: Select PrepsMarkRulesEditor > Preferences.
   • In Microsoft Windows: Select Tools > Options.
3. In the Preferences dialog box, load the profile to be used and set the Unit for specifying dimensions in the criteria settings.
4. Click [+] to add a new rule.
5. Configure the criteria in the rule settings.
   It is not necessary to provide a value for each setting. For example, a generic rule to apply crop marks to all auto-created signatures might contain only the rule name.
6. In the SmartMarks list, choose a mark to be applied by this rule. Double-click it to add it to the Marks to be added list.
   Note: Add as many marks as desired for this rule.
7. Click Save Rules.
8. Repeat as needed to set up additional rules.
9. To activate the rules for JDF auto signature creation, enable the Add SmartMarks based on mark rules option on the JDF tab of the Preferences dialog box.

• The mark rules are added to the markrules.xml file in the Printers folder.
• For JDF auto signature creation, rules are applied based on the JDF data's work style, binding type, front and back colors, and sheet size (or size range).
• For AutoGang, rules are applied based on the flat work binding style and specified sheet size in the AutoGang Preset.
• When more than one rule matches a press run, all matching rules are applied.
