La apariencia de la superficie puede cambiar su percepción del color. Piense en una revista con brillo. Si la luz brilla directamente sobre la página, es probable que deba inclinar la revista y cambiar el ángulo de reflexión para ver claramente los colores. De igual manera, una superficie texturizada puede parecer de un color diferente al de una superficie lisa del mismo objeto. Dado que los espectrofotómetros determinan los valores espectrales de un color ilu...

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° - ...

Spectrophotometers are color measurement devices that measure color to ensure it remains consistent from the time it’s specified until final quality check. They can be used to measure everything from liquids and plastics to paper, metal, and fabrics for just about every industry. Here Are Our Top Spectrophotometer Picks for 2019. Best Spectrophotometer to Create Digital Standards Using a digital standard is the most accurate way to specify and communicate color, des...

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 ...
