Abstract
The invention presents a method for controlling the composition of an ink mixture (11, 31) for at least one printing press (2), in which actual optical values (I) of light (7) are obtained, whereas the light (7) has interacted at least with parts of the printing picture, which is generated by the printing press (2) on the printing substrate (6) using an ink mixture which is provided by an ink supply system, and in which, due to the deviation of the actual optical value from optical reference values (S), a corrective ink mixture (31) is created, which is added to the ink mixture (11) which is provided by said ink supply system and which changes the ratio of the amounts of ink pigments therein. The ink mixtures (11, 31) used in the method are provided by different ink mixing devices (16, 24).
