Margin Options

Example of perforating margin, JBL speaker grille

Intermediate Margins

These are the unperforated areas inside the perforated sections used to achieve a particular design or appearance.

Safe Side Margins

This type of margin is achieved by perforating the material all the way up to the edge but not on or over the edge.

End Margins

The distance from the end of the sheet to the first perforated section parallel to the end edge.

Side Margins

The distance from the side of the sheet to the first perforated section parallel to the side edge.

Selective Area Margins

Unperforated sections in the middle of the perforated sheet typically in a rectangular shape.  Some selective area margins can be abnormally yet linear-shaped.  Selective area margins are achieved through a computer-controlled tooling system on selective perforating presses.

No Margins

Holes are perforated onto the edge of the material.

Skip Feeds

Areas parallel to the width of the sheet that are intentionally unperforated or skipped in order to achieve a particular design or appearance.
