Duplexing labels

Labels are not typically duplexed because of their special construction. However, printing on both sides of the label sheet may be possible if certain design, construction, and usage guidelines are followed.

When developing a paper label for duplexing, the converter should make sure that the label is designed to protect against contamination or buildup. Contamination results in paper feed problems and jams.

We recommend the use of label sheets that have a non‑adhesive border around the label area. Make sure that the release strength is enough to withstand temperatures of 225°C (437°F) and pressure up to 25 psi.

Use label ties as needed. These small uncut areas (approximately 1.6 mm or 0.06 in.) help stabilize the label sheet and prevent tearing at perforations and die-cuts during printing. Label ties also prevent labels from predispensing in the printer.

The slits and cuts in the labels expose the adhesives to the printer. For best results, position the label sheet so the slits and cuts are not aligned with the ribs in the duplex or redrive areas of the printer. Doing so eliminates any contact points between the label adhesive and the printer and prevents any adhesive contamination in the printer. For more information, see Primary rib pattern design guidelines for reference edge alignment.

Load label sheets with the label end first. Use grain long paper instead of grain short paper, which tends to curl easily.

If a converter develops a grain short label sheet for duplexing, then test the sheet first to make sure that it works satisfactorily.

Note: We recommend testing any material with your application and printer before purchasing large quantities.

To use the duplex label application, you may be required to install a fuser wiper. The wiper allows the printer to print on both sides of paper labels. To determine whether your printer requires a wiper, see "Printer-specific paper support."
