Dimensional Stability - What is dimensional stability?

Answer:

A property of materials that allows them to maintain their original shape and dimensions throughout the manufacturing process, storage, and use. A material with good dimensional stability will resist any change in its dimensions caused by a change in environment, or by being stretched or compressed.

In labelling, the dimensional stability of sheets of labels is most commonly affected by humidity (which can increase or decrease their moisture content) and the manufacturing and printing processes.
