Differences between an offline spectrophotometer and an inline spectrophotometer can result in differences between a hardcopy target color and a printed reproduction of that color. The inline spectrophotometer is inside of a printer and configured to measure printer output. As such, the inline spectrophotometer cannot conveniently measure the hardcopy target color. A printing error or an instrument offset can be determined and passed to a color correction module that updates the device dependent color specification associated with the given spot color. This color specification may be stored, for example, in the printer controller, and used when a document subsequently calls for that spot color, thereby providing accurate color reproduction from that particular printer incorporating that particular inline spectrophotometer.
