Abstract

Techniques for reducing or eliminating image banding in an ink-jet image are provided. In an example, a method of operating a printer to reduce or eliminate image banding can include generating command profile for printing a given image, applying a filter to the command profile to provide a filtered profile, and dispensing ink from a printhead of the printer based on the filtered profile. In certain examples, the filter can randomize droplet sizes of ink dispensed while executing the printing to reduce or eliminate image banding.
