Abstract
In a method for operating an inkjet printing machine, a condition of an ink is determined. A sedimentation and/or agglomeration of a pigmented ink is determined by refractometry, i.e. the value of the refractive index of the ink is measured with a refractometer and compared with a stored value with computer assistance.
