Lighting audit according to ISO 3664:2009

Besides our successful certifications, as of 2017 we offer a check of the technical measurements of your colour matching spaces in the print shop and/or pre-print stage area as part of a lighting audit considering their conformity with ISO 3664:2009.


Besides all of the important requirements for standardised offset printing, the right colour matching conditions in your pre-printing stage and in the print room come back into focus again and again with the implementation of the new ISO 12647-2:2013. It is only in this way that an optimal visual comparison of the test printing and production printing can be ensured.


In our professional lighting audit, we test whether the lighting you have used fulfils the right requirements and can provide you with a recommendation for optimising the lighting situation if needed.


The audit takes place with the most modern measuring device of the company Just Normlicht, the ‘GL SPECTIS’.


This tests


  • Illuminance: 2,000 Lux; Tolerance +/-500 Lux  
  • Colour temperature: 5,000 Kelvin
  • Metamerism index 
  • Colour Rendering Index (CRI): > 90
  • Brightness and light distribution on the matching surfaces 
  • Creation of a test protocol and an analysis of planned and actual results


We offer the lighting audit as a half-day service on site at your printer’s. You can add to the audit by booking an additional option of a PSO, premium PSO or a digital printing certificate.


If you have questions about a lighting audit, implementation or costs, you should feel free to contact us at any time.
