ABSTRACT:
An apparatus and method for calibrating a multi-color imaging system are provided. Color values are measured for each of the different color patches, and compared to target process-sensitive colors color values, representing a weight-adjusted memory color. An error value is calculated. The error value represents a deviation of the measured color values from the target color values. The input values for each colorant then are independently adjusted to reduce the error value to a predetermined degree.
