Abstract
A system is provided for receiving R, G and B data in digital form, such as produced by an artist using a 'paint' program on a monitor screen, and converting such data to CMYB data for printing. The system independently determines tone correction values for grey balance control and color values and combines such values to produce a highly accurate reproduction of what is viewed on a screen. Calibration procedures are provided which rapidly converge and which allow quick and accurate adjustment, such as may be required to match a particular monitor and printing inks.
