Coding & marking refers to applying codes, markings, or labels to products, packaging, or materials for identification, tracking, and compliance purposes. This process involves using specialized equipment, such as printers, coders, and markers, which use inkjet or thermal transfer techniques to apply codes or markings. The codes & markings can contain important information, such as batch numbers, codes, and logos, which help manufacturers comply with regulations, improve traceability, and enhance brand recognition.
