Bonjour Roger, Fogra 51 and Fogra 52 were not created by just taking measurements from a print. The characterization data sets, especially of Fogra 51, is the result of a comprehensive process of optimization, statistical evaluation, comparing results and final decision of a group of ECI experts. The more than 15 print series at german, swiss and austrian printing companies were initiated and accompanied by bvdm (myself) and overseen by ECI experts. The measurements taken for Fogra 51 were all M1 (with additional M0 and M2 measurements to evaluate the differences). All this was intense and hard work of ECI experts (Hanno Hoffstadt (key person), Florian Suessl, Jurgen Seitz, Roland von Oeynhausen et al). When the final characterization data set (Fogra 51) was fixed and passed, it was given to Fogra to create the official data for publication in the series of Fogra characterisation data. Most of the Fogra chardata were created in a similar way, e.g. Fogra 27 ff. with the development of Altona Test Suite reference prints (2003-2004), Fogra 39 ff. with the edition of ISO 12647-2 (2007) and with the development of web offset chardata and profiles by ECI web offset international working group, supported by bvdm. The corresponding ECI profiles were created and published by ECI. The „making of“ was reported e.g. at the launch of the new printing conditions (ECI Profiles, Fogra 51, 52) on September 30, 2015 in a special event at Stuttgart Media University (HdM). The comprehensive documentation (with many related topics such as PDF/X, ISO Standards for prepress and print) is available: MediaStandard Print (2018) free PDF download from bvdm website: https://www.bvdm-online.de/themen/technik-forschung/richtlinien-und-handrei… There is a mix of german and english documents for download on this website (e.g. also the ECI bvdm CrayCon series – Gray Control Strips). Just scroll down. Best Regards Karl Michael Meinecke (bvdm technical expert 1980-2017) *** Karl Michael Meinecke, Dipl.-Ing.

Just “M1”? Or was it a “combination” of the same press sheets measured with different instruments, all in M1 mode, like with an X-Rite eXact oder eine Techkon Spectrodens oder eine Minolta FD-7? Enshuldigen sie if I missed this and it is already mentioned on Fogra excellent web site ☹ MfG / Roger Breton www.graxx.ca
