发明名称 Apparatus and method for recalibrating a multi-color imaging system
摘要 <p>An apparatus and method for recalibrating a multi-color imaging system (10) are provided. The multi-color imaging system (10) is capable of applying different colorants to a substrate (34) based on a plurality of input color values. The input color values control amounts of the colorants to be applied to the substrate by the imaging system. A subset of the input color values is selected and used to control the imaging system to apply one or more of the different colorants to the substrate, thereby forming a plurality of different color patches on the substrate. The subset of input color values is selected such that one or more of the different color patches is formed by application of a combination of at least two of the different colorants to the substrate. Color values are measured for each of the different color patches, and compared to reference color values, representing a calibrated condition of the imaging system. An error value is calculated. The error value represents a deviation of the measured color values from the reference color values. The input color values for each colorant then are independently adjusted to reduce the error value to a predetermined degree. &lt;IMAGE&gt;</p>
