Abstract:
A method and apparatus are provided by which optimum usage of available color space of an output device, e.g. an inkjet printer or laser printer, is achieved. Gamut compression is dynamically computed by being dependent on contents of a print job, as opposed to only using pre-calculated or static tables or ICC rendering intents.
