    • The measurement fields are optically scannable and are printed on a print prodn. to be controlled or on a standard print. A first combination measurement field (1) is involves in which the basic colours, in partic. the three colours cyan, magenta and yellow, are printed one on top of the other with their nominal surface covering degrees (Fct,Fml,Fgl). Additional individual colour raster fields (8,9,10) in the basic colours in their basic colours have a surface covering degree which corresponds to the same colours in the first combination measurement field. The measurement field group contains additional combination measurement fields (2,3,4) in which the basic colours with varied nominal surface print degrees are printed one on top of the other, whereby each basic colour at least once is varied and in each additional combination measurement field at least another basic colour is varied.
