Quality markings are used in quality control processes for marking the status of the product being checked. Depending on the company’s internal arrangements, the marking may take the form of a self-adhesive label or a tag. In order to distinguish the products which have passed the quality control, have passed it conditionally or have been rejected, the appropriate colours of markings are applied: green, yellow and red. Sometimes a graphic form of communication, e.g., OK, NOK or plain text: “compliant”, “non-compliant” are used.
