Learn more about light, reflection curves, optical brighteners, and more.     Illuminants Electro magnetic radiation in the wavelength range from 380 nm to 730 nm is seen as light by our eyes. Low wavelengths show as blue light. Then the spectrum continues from green, yellow, orange to red. UV radiation is located in the range below 380 nm; the range above 730 nm is called infrared radiation. The visual impression of a colored body changes by the composition of the incoming light. ...

Consistent color is a journey. A few weeks ago I blogged about the most common pitfalls people run into when starting a color program… Wrong lighting Less-than-perfect color vision Inaccurate physical standards Inconsistent device color measurement …And introduced some inexpensive color tools to help overcome them.   But the journey doesn’t stop there. Even if you’ve been successfully managing color for years, advances in inks, dyes, and substrates are introducing new challen...

Color measurement devices have been around since the 1940s, but they’ve come a long way since then. Built by Jules Duboscq in France in 1870, the Duboscq colorimeter was one of the first color measurement devices. The earliest instruments were colorimeters, which used red, green and blue filters to simulate the tristimulus response of the human eye. Back in the ‘40s, they were pretty expensive so few people had access to them. Even more expensive were spectrophotometers, which meas...
