Press Punching

A web press has the ability to punch file holes into printed products during the printing operation. Consider the following points when planning an application with press file hole punching:

• Standard configurations are:
  - two holes, 2 3/4" center to center, top or bottom of the application.
  - three holes, 4 1/4" center-to-center on the left side of the application.
• Configurations other than standard may have restrictions so it is best to consult the print provider for information on their capabilities.
• Press punching is less expensive on larger runs due to the efficiency of printing and punching an application in one operation.

Bindery Punching

File holes may also be punched as a secondary or "off-line" operation in the bindery department. Consider the following points:

• The standard configurations are the same as for the press punching.
• There are no restrictions on non-standard punching configurations.
• Bindery punching is more expensive on longer runs due to the additional labor involved in being an offline operation.
