Para hacer la medición del color, un dispositivo ilumina con una luz brillante una muestra, captura la cantidad de luz que se transmite o refleja en una longitud de onda en el rango de 380 nm a 780 nm, y la cuantifica como una medición espectral. La medición del color es necesaria para especificar, cuantificar, comunicar, formular y verificar la calidad del color en los trabajos en los que los colores tienen una importancia crítica. Debido a ...

Reflective surfaces and metallic inks are very popular for printing and packaging applications. Consumers love the look; but for printers, these substrates and inks are expensive and make color control a challenge. Today we’re taking a look at the measurement options available for controlling these very marketable print and packaging applications to help printers and converters meet brand owner expectations and maintain the highest possible quality output. Sphere vs. 45°:0° - ...

The two most common spectrophotometers are the 0:45 and the sphere (aka diffuse/8°). We get a lot of questions about which is the best choice. Here’s the difference in how these two devices measure color, and guidelines for when to use each. 0:45 In a “fixed geometry” or “single angle” device, the first number is the starting point of the light, and the second number is where the light ends up after the reflection off the surface of the sample. In a 0:45 ...
