ABSTRACT:
The output mode of an output device for rendering electronic images on an output medium may be characterized by different user-selectable settings such as: paper type, ink type, etc. Apart from the screen characteristics such as screen ruling, frequency and angle, a calibration curve can be communicated via the page description language (e.g. PostScript Level 2) for each color component. Sets of calibration curves can be prepared for specific types of rendering, and be referenced by name. By this name indirection and by naming conventions based upon the output mode or screening parameters, calibration changes can be introduced quickly and consistently.
