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° - ...

Controlling color on cylindrical-shaped items like cups, cans, and tubes is a challenge because it’s hard to properly align the measurement device with the sample. Many printers and manufacturers cut a piece from the finished product and lay it flat to take a measurement. While this method works, each sample takes time to cut, wastes product, and risks the safety of the employees who are cutting the samples. A Faster, Safer Solution X-Rite’s Cup and Cylinder Fixture works ...

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 ...

Ganz gleich, was Sie herstellen: Farbmessungen sorgen dafür, dass Ihre Farben während der gesamten Produktion präzise und konstant bleiben. Bei der Auswahl des für Ihre Anforderungen am besten geeigneten Spektralphotometers sollten Sie vor allem die Art der zu messenden Oberfläche berücksichtigen. Die Farbmessung bei glänzenden Oberflächen ist problematisch, weil Glanz die Farbwahrnehmung beeinflusst. Glanz entsteht, wenn eine Oberfläche das auftreffende Licht spiegelnd reflektiert. Da Spektra...
