"Color information can theoretically be devided into the components of image analysis (grabbing), signal processing and image synthetis (rendering).

The visual color information of the original is captured by image analysis. The observer - the sink of the reproduction system - will receive the visual color information in terms of the reproduced image. An important requirement for reproduction systems is the transmission of lossless visual information without any disturbance.

For this, all components of the reproduction system have to consider the physiological perceptional properties of the sink, the human visual sense."
