Abstract: In a method to adjust print quality of print images in an electrophoretic digital printer with at least one print group, the print group generates charge images of the print images. The charge images are developed with a developer station into toner images using liquid developer having carrier fluid and toner. The toner images are transfer-printed onto a carrier medium in a transfer station. A first control marking is generated on the recording medium with elements of the first control marking being aligned transverse to a printing direction. A shape of the elements of the first control marking is measured to generate a first measurement signal. The first measurement signal is compared with a predetermined nominal value, and given a difference, an adjustment signal is generated via which an amount of the carrier fluid in the liquid developer is modified so that the first measurement signal approaches the predetermined nominal value.

Abstract: In a method to control a color printer or color copier, a color separation of a first color and a color separation of a second color are applied to a printing substrate to generate a print image. Also, with aid of a printing unit, at least a first control field is printed on the printing substrate. The first control field has a predetermined pattern that includes at least the first color and the second color and is designed such that a color value of the first control field changes depending on a registration error between the first and the second color separations. A reference field is also printed on the printing substrate, a pattern of the reference field being predetermined such that it has a same color value independent of the registration error. The color value of the first control field is measured with a color value sensor. The color value of the reference field is also measured with the color value sensor and a desired color value is determined depending on the color value of the reference field.
