Are there standards for the cleanliness of a printing facility?

While there are no external standards, some companies adhere to the Lean manufacturing concept of 5S and establish their own standards. 5S is a method of workplace organization and cleanliness so abnormal conditions are immediately visible. Companies producing packaging or labels for food clients may be asked to adhere to Good Manufacturing Practices (GMP) for Production of Food Packaging. These cover cleaning, sanitation, pest prevention, personal hygiene, and other practices for the control of food safety hazards. Developing and demonstrating your own standards is wise, even essential, depending on the markets you're serving.
