Summary:In a device and a method for improving the print image uniformity, at least one print image is printed by a printer with at least one print bar that has at least one print head with a plurality of print nozzles. An image detector having a plurality of dot/image detection regions detects at least one value profile of measured inking intensities. A comparator compares the value profile with at least one reference value, and generates correction values dependent thereon.
