One question we hear often is “What are the best practices for applying Delta E (or the color difference from one measurement to the next) tolerances.” The answer? It depends. Color matching is an indicator of quality, but the level of uniformity can vary by color, product, application, or business need. Here are some things to consider when determining your own Delta E tolerances:
The quality demands of your customers
Agreement with visual assessment
The DE* calculation to be used. We recommend CIEDE2000 or CMC.
One size does not fit all. White and pastel colors may have different perceptibility/acceptability versus deep and high chroma colors
The color accuracy of competing products
Your time constraints. If you set strict tolerance standards, does your team have the time and resources to ensure your products meet those standards and maintain production throughput?
The cost/benefit ratio of improved color matching. The right tools are an investment, but they’ll help you achieve more first-shot matches and over time save you money
