Abstract: The repeatability and inter-instrumental agreement of reflectance spectrophotometers have been investigated in this study. Both glossy and matt types of standard tiles were used and it was found that the different spectrophotometers differed considerably with one another. A new mathematical model for inter-instrumental agreement (the R-model) was developed. The improvement of the inter-instrumental agreement after applying the model was 82-90% with the appropriate measurement settings. The concept of using an instrumental profile for a spectrophotometer against a reference instrument was tested and the results of the inter-instrumental agreement after applying the profiles also showed significant improvement. The performance of the R-model was compared with the two previously published models and the results showed that the R-model outperformed the other two models based on the measurements of both standard tiles and textile samples.
