spectro2guide PRO - Quantifying Jetness

Learn more about the spectro2guide PRO and how it provides reliable results in color, gloss and fluorescence measurement, as well as Jetness measurement of deep black colors.

It has always been the greatest challenge for a spectrophotometer to achieve repeatable and reproducible results on a black color. While a white sample reflects almost 100 percent of the light emitted by the spectrophotometer, the proportion of reflected light becomes smaller and smaller with darker colors - as increasingly larger amounts of light are absorbed by the sample. Consequently, the so-called "signal to noise ratio" changes with dark colors: The measurement signal decreases while the thermal noise, which is basically caused by electronic components, remains constant. Measurements of innovative, deepest black coatings with very low reflection takes place at a lightness value of L* smaller than 1. This is a challenging task for a measurement instrument and pushes the technical performance of a handheld spectrophotometer to the utmost limit.
