    摘要: An image reproduction system with requisite technology to reduce or eliminate altogether banding effects is provided. The system includes an input tray for storing print media, an output area for holding printed media and an inkjet pen or printhead for printing information on the print media. In a preferred embodiment, the reproduction system is inkjet printer whose pen scans and ejects ink on the print media with a non-uniform dot pitch. This non-uniformity is achieved by adding visual noise in a known and predictable fashion to the uniform dot pitch.
