Sometimes when the temperature of the same object changes, its color will also change. This phenomenon is called thermochromism. In order to more accurately measure color using a Spectrophotometer . The measurement needs to be carried out in a room with a fixed temperature and wait until the measured object has reached room temperature.
When the room temperature changes by 10, the temperature characteristics of BCRA standard color plate (△E*ab) (according to Konica Minolta test conditions)
