Color changes as ink dries. This affect slows after a certain time, based on the media, ink, temperature, and humidity. The default calibration drying times are intended to optimize the trade-off between color accuracy and ink drying time. If you reduce the ink drying time for a calibration, the accuracy of the calibration and subsequent proofs may decrease, especially after the ink dries on the proof.
In the Inline spectro calibration chart (minutes) box, specify a new value.
