1. Print Performance

Lineless labels typically require a higher print darkness setting than standard direct thermal labels. The heat generated by the printhead must penetrate through the release coating to activate the direct thermal chemistry to create a readable and durable image. In addition, extended print quality testing is required to ensure the release coating does not build-up on the printhead.

2. Proper Manufacturing

Linerless labels must be carefully manufactured and precisely wound on the core to ensure a proper fit in the printer. Unlike standard labels, linerless labels cannot be easily adjusted on the roll because of the absence of the liner. To prevent printer feeding issues or jamming, it is important that the label release coating has cured properly during manufacturing and the adhesive chemistry is compatible with the platen roller.

If you’re using a Zebra linerless printer, labels must be properly attached to the core to ensure the sensor can read and indicate when you have run out of media, and to prevent jamming.

3. Testing and Maintenance

To minimize cleaning and maintenance-along with having to replace printheads and platen rollers-linerless media needs to be rigorously tested in compatible printers to ensure minimal adhesive buildup, optimal print quality and smooth label throughput.
