Abstract
Broadly speaking, embodiments of the present technique provide apparatus and methods to print an image using masking techniques that control the operation of a droplet deposition head having at least one faulty nozzle. More specifically, an image is analysed to determine a pixel colour density for each pixel of the image. A masking technique is provided which may distribute the droplets (or sub-droplets) that a faulty nozzle is assigned to print among one or more neighbouring, functioning nozzles.
