The goal is to ensure that the multiple division of labor production process is as efficient as possible and at the same time to ensure that interim and final results show a predictable quality of color.
The ISO 12647 Process Standard Offset print is in constant development in order to benefit the user.
In order to fullfil the goals of ISO 12647, other standards like ISO 12646, ISO 12646-7, ISO 3664, ISO 13655 and parts of ISO 9000 have to be fulfilled. All these standards are subsumed under the term ProcessStandard Offset (PSO).
Since the certification is mostly applied in offset printing the title is chosen PSO. But the certification is easily adapted to Process Standard Newspaper (PSN) and Process Standard Rotogravure (PSR). Since there are standards for Screen and Flexo printing available as well the certification can be adapted to this printing methods too. Of course diigital printing can be certified as well.
