At Proof.de, with regard to the two predecessor standards Fogra49 and Fogra50 for glossy and matte film lamination of ISOCoatedV2 / Fogra39 prints, the majority of inquiries were for the standard for matte film lamination only, as this is where the greater and more difficult effects occur with regard to colour changes due to the lamination process. Particularly in the area of colour-critical prints, such as catalogues for the automotive industry, extensive tests are sometimes carried out with different film laminations in order to be able to recognise and compensate for differences between a normal matte film lamination and a scratch-resistant matte OPP lamination, for example. We also expect a higher demand for consulting and proofing for Fogra56 and Fogra57 for matte film lamination.
The European Colour Initiative ECI states on its website that the differences between different glossy films are rather small, while matte films are available in very different opacities. According to the ECI, the “average” matte film used as a reference in FOGRA56 leads to a lightening of ∆L* = 6 in the black solid tone and fits well with typical production. The lightening is lower with more transparent foils and higher with matte foils. In order to be able to assess one’s own films, the ECI recommends measuring the black solid tone before and after finishing on the same field on the same sheet.
