Certification system for a standardised production standard in the offset printing sector. (The certification by SQS is not offered any longer. Existing certificates stay valid until the end of their validity.)


The swissPSO label stands for comprehensive quality across the entire project workflow, from initial customer contact through to the disposal of waste.
Good print products are created thanks to perfect organisation. This has led swissPSO to place an emphasis on the areas of organisation and documentation. Particular attention is given to the process interfaces.
Process security is ensured by the fulfillment of clearly defined and narrow tolerances in accordance with the standard ISO 12647. However, swissPSO goes beyond previous efforts in the field of standardisation, by integrating further processing.


swissPSO is an initiative of Viscom. swissPSO is breaking new ground. For the first time, quality management system not only covers production processes but requires excellent companies to implement specified criteria for customer support, service and processing, as well as compliance with environmental standards.
