Thickness - What does thickness mean?

Definition of THICKNESS:

A measure of the distance between two surfaces of an object, usually the smallest of three dimensions (length, width, and thickness).

In labelling, the thickness of face materials, backing sheets, and finished sheets or rolls of labels needs to be measured carefully; thickness is usually expressed in microns (one thousandth of a millimetre) or mils (one thousandth of an inch). It is important to know the thickness of the materials used to make label products as dies are often designed to cut to a specific depth and if the materials are of the wrong thickness, the die may either not cut deep enough into the face material (making it difficult to remove a label) or may cut too deeply (which could cause a label to separate from the backing sheet entirely). It is also important to know the thickness of labels when printing as thicker sheets and rolls may not feed through or fit correctly with some printers.
