What does "core size" refer to when ordering roll labels?

Core size refers to the inner diameter of the roll, meaning the cardboard tube the labels are wound around. It determines whether the roll fits your applicator or dispenser.

• Standard core: 3 inch inner diameter, the most common size
• Smaller core: 1 inch, offered by many printers on request
• The core size must match your dispenser or automatic applicator
• Hand application is generally not affected by core size

A roll with the wrong core may not load onto the spindle of your machine at all.
