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.
