Abstract (en)
[origin: WO2009071673A1] Method for generating a security code for an optically readable matrix printing data memory which has a high data density and is applied to an object or printing material with the aid of a multistage printing process, characterized in that the individuality of at least one stage of the printing process is measured and compared with the desired values and a security code is calculated therefrom and is stored, and an object having a colour matrix printing data memory which has a security code and is applied in a multistage process.
