Choosing the right lighting for color evaluation
Companies concerned with the color quality of their products may use sophisticated instruments to make sure their processes adhere to tight numerical specifications, but they can easily overlook the need to do proper visual evaluation of colors and color differences as part of the quality control process.
While readings from a spectrophotometer may show that a process is running within specification, a company could still be turning out unsatisfactory parts if the product color isn’t what the customer expected when goods are arranged on store shelves. At some point in the supply chain, people need to visually evaluate how colors look when they are placed together under approximately the same illumination as where they are sold or used.
By implementing proper illumination and procedures for visual evaluation according to best practices, companies can achieve an advantage over competitors, while also reducing waste, rejects and rework.
