Abstract: A printing system for printing on a material has an ink formulation module (18) for providing an ink recipe, a printing unit (12), a sensor for generating color measurement data (CMD), and a control module (16) being connected to the sensor (14) and to the printing unit (12). The color measurement data (CMD) comprises at least one actual ink color value and the control module (16) is configured to receive at least one unit parameter (UP) from the printing unit (12), to receive the color measurement data (CMD) from the sensor (14) and to transmit the at least one unit parameter (UP) and the color measurement data (CMD) to the ink formulation module (18). Moreover, the ink formulation module (18) is configured to create at least one adjusted recipe (AR). Furthermore, a method for adjusting an ink recipe of a printing system (10) is provided.
