Approval of fountain concentrates
The corrosion and polymer swell tests follow a procedure that was developed in cooperation with all german press manufacturers (Heidelberger Druckmaschinen AG, Koenig & Bauer, manroland Goss web systems GmbH, manroland sheetfed GmbH). The approval and thus the certification of the fountain concentrates is carried out by the respective manufacturers.
Approved products are entered and published both in the manufacturers' databases and in the FograCert database. On the product itself you can indicate the approval in the form of a FograCert logo.

Our procedure
After receipt of the order by Fogra you will receive an order confirmation which contains all details of the test period, contact person and price. The processing period for an approval test (complete or repeat test) is usually approx. 4 to 6 weeks.
Before the corrosion tests and the polymer swell test are carried out, the pH and conductivity measurements are taken. To enter the testing procedure, a fountain solution must fulfil the following criteria:
pH value: 5.0 ± 0.2 to 9.0 ± 0.2
Electrical conductivity of fountain solution limited to +1800 (coldset-/heatset) and +2000 μS/cm (sheetfed) above the conductivity of the water used to prepare it
After completion of the tests, Fogra sends all results in the form of a final report to both the customer and the press manufacturer. On the basis of the test results, the manufacturer decides whether the product can be recommended for use on the press. In case of a successful certification the manufacturer authorises Fogra to issue the test certificate or to extend the release. Furthermore we list your fountain concentrate in our FograCert database.
