CRI+ FOR ACCURATE COLOUR MATCHING
Work lights to be used for colour match purposes must have a light source with a high CRI value. The standard CRI value is calculated as an average of the first 8 R-values out of 15. This means that e.g. the R9 (red) value, which is important for correct colour recognition, is not taken into consideration for the CRI value.
SCANGRIP now introduces the CRI+ term defined as an average of all 15 R-values. This is the only correct definition of the CRI value to be used for accurate and reliable colour recognition.
