Recent Developments in Colour Rendering Indices and Their Impacts in Viewing Graphic Printed Materials

摘要

A new colour rendering index was developed. It has thernfollowing features: to use CAM02-UCS model including a robustrnchromatic adaptation transform and a uniform colour space, tornapply 10~° observer to remove the anomalies of the 2~° observer inrnthe close to blue area, to include 273 test samples to cover a largerncolour gamut corresponding to real world samples. It is a muchrnimproved CRI than the current CIE-R_a.
