Color Analysis of heat yellowing and light fastness tests on leather The SmiTool Light and Heat already discussed the subject of heat yellowing and light fastness tests on leather. The current SmiTool explains the differences between subjective and objective assessments of tested leather and how to report test results for heat yellowing and light fastness. For color analysis an X-Rite spectrophotometer is being used. This equipment enables us to analyze color in an objective way. Why is this so important? When color changes are evaluated by the human eye, all kinds of factors will affect the color perception: Age (older people tend to see more yellow)Fatigue Lightning conditions (artificial/natural) Background and contrasting colors Texture of the material (suede/aniline/embossed) Color deficiency With the spectrophotometer, the analysis can be done in a standardized manner, anywhere, anytime. For a good evaluation of color without respect to gloss or texture, the setting is set for D65/10 illuminant and SPIN . Learn more about this topic? Download the whitepaper below.
