The production of pressure-sensitive labels involves a quite complex process of printing with up to 10 or more printing units, sometimes using two or more different printing processes. Ancillary operations typically follow as needed to die-cut the labels to shape, remove the waste material, trim the edges of the web and slit it into single roll widths – or sometimes into single sheets – prior to a final inspection, re-winding and then packing before shipping to the customer.

Depending on the specific label application, the types of labels to be produced and their added-value requirements or complexity, it may also be necessary to undertake a variety of other types of finishing or embellishing operations, such as varnishing, embossing, hot or cold foiling, perforating, scoring, sheeting or hole punching.
