1. A printing system for printing on a material, the printing system comprising:
an ink formulation module for creating multiple ink recipes,
a printing unit for applying ink to the material,
a sensor for generating color measurement data of the ink applied to the material during a printing process, and
a control module connected to the sensor and to the printing unit,
wherein the ink applied to the material is a composition of different base colors mixed together to form a new color having specific properties,
wherein each of the multiple ink recipes is instructions to mix the ink for the printing unit, and each ink recipe includes colors to be mixed, an identification number, and/or quantities of the colors to be mixed,
wherein the color measurement data comprises at least one actual ink color value of the ink applied to the material by the printing unit,
wherein the control module is configured to receive at least one unit parameter from the printing unit, to receive the color measurement data from the sensor during the printing process, and to transmit the at least one unit parameter and at least parts of the color measurement data as a single recipe request to the ink formulation module,
wherein the ink formulation module is configured to create the multiple ink recipes based on the single recipe request and transmit the multiple ink recipes to the control module, and
wherein the control module automatically selects one of the multiple ink recipes for application of ink made with the selected ink recipe during the printing process, and wherein the automatic selection is based on at least one parameter associated with each of the multiple ink recipes.
