White Papers - The steps to consistent color in plastics

Expert color control at every stage of production is vital to quality control, cost, client satisfaction, and retention. Spectrophotometers and colorimeters are instruments used to illuminate an object at certain angles to detect its color. Once the lighting of a sample has been established, a standardized perspective must also be determined. Due to variations in reflection, the angle of light chosen must be as consistent as the type of light used.

Blog: Color measurement of plastics bottles and tops

In the CPG (Consumer Packaged Goods) industry, package quality is an important factor. To control quality many companies have tight specifications and controls on the color of their packaging. Color needs to be measured at different stages to ensure the final color is correct. The measurement of the color of the bottles, caps, and closures, involves four stages: product development, raw material incoming inspection, bottle preform, and cap and closure inspection at the end of the production process.
