ISO 12647

In the ISO 12647 the ISO norm for standardized printing. It shows the main cornerstones for standardized, color-accurate prints.

The ISO 12647 is divided into 8 sections:

The authorities responsible for the proofing requirements are therefore in the standard ISO 12647-7. The year after the colon refers to the year of the current valid version of the standard. The ISO 12647-8 for the Validation Print was so last updated in 2012.


PSO stands for “ProcessStandard Offset Printing”, a standard that was developed by Fogra and the German Printing and Media Industry together. The ProcessStandard Offset Printing is a set of standards for offset printing. With test equipment and control by measurments as described in the PSO, the printing process of the data delivery and data preparation on the platemaking is monitored, controlled and checked.

The following standards are summarized in PSO – “ProcessStandard Offset Printing:

ISO 00005-4: Optical density
