Surface appearance can change your perception of color. Think of a glossy magazine. If the light is shining directly on the page, you may need to tilt the magazine and change the reflection angle to clearly see the colors. Likewise, a textured surface may appear to be a different color than a smooth surface of the same object. Since spectrophotometers determine a color’s spectral values by shining light onto the surface and measuring the reflectance, choosing the right instrument an...
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 ...
