A method of color calibration for different spectrophotometers

Because the type and grade of the spectrophotometer and different measuring conditions and so on, there are some diffences of color values measured by spectrophotometers in printing industry. In this paper, we present a method of emending color measured by different spectrophotometers. This method emends the color data measured by different spectrophotometers using Pantone color cards as criterion to reduce chromatic aberration.
