Coding, Marking, and Labeling Glossary of Terms

A

  • Applications

    In industrial marking and coding, an application refers to the specific set of conditions under which a product or package must be marked. This includes factors such as the production environment (e.g., temperature, humidity, cleanliness), product or packaging shape and size, substrate material (e.g., plastic, glass, metal), line speed, and the type of code or information required (e.g., date codes, barcodes, logos). Understanding the application is essential for selecting the appropriate coding technology to help ensure reliable, legible, and compliant marks.
