Your benefit

Even in the digital age it remains necessary to preserve data on analogue information carriers such as books. The certification of resistance to ageing in accordance with the relevant ISO 9706 standard ensures that documents are not damaged even after long periods of storage in archives and libraries.

The certified papers are entered into the FograCert database and published. On the product itself you can indicate the certification in the form of a FograCert logo.
