How Closely Does the Sample Match the Standard?Even if two colors look the same to one person, slight differences may be found when evaluated with a color measurement instrument. If the color of a sample does not match the standard, customer satisfaction is compromised and the amount of rework and costs increase. Because of this, identifying color differences between a sample and the standard as early in the production process as possible is important.
Color difference can be defined as the numerical comparison of a sample’s color to the standard. It indicates the differences in absolute color coordinates and is referred to as Delta (Δ). These formulas calculate the difference between two colors to identify inconsistencies and help users control the color of their products more effectively.
To begin, the sample color and the standard color should be measured and the values for each measurement saved. The color differences between the sample and standard are calculated...
