CALIBRATION OF AN IMAGE SCANNER IN A PRINTING SYSTEM

Aspects of the disclosure provide for a method. In some examples, the method includes printing a target plot comprising a color ramp, scanning the target plot via a first image scanner to determine first scan results indicating a relationship between a scanned measurement determined by the first ima...

Zusammenfassung:	Aspects of the disclosure provide for a method. In some examples, the method includes printing a target plot comprising a color ramp, scanning the target plot via a first image scanner to determine first scan results indicating a relationship between a scanned measurement determined by the first image scanner and lightness of a scanned portion of the target plot, scanning the target plot via a second image scanner to determine second scan results indicating a relationship between a scanned measurement determined by the second image scanner and lightness of the scanned portion of the target plot, and determining a lookup table indicating a difference determined based on the first scan results and the second scan results.
