Konica Minolta Croatia: Objective Color Control Reduces Errors and Customer Complaints
In many manufacturing facilities, the rule still applies: if an experienced quality inspector says the color is acceptable, the batch moves forward. However, manufacturing should be driven by data rather than subjective judgment.
The issue is not experience—it is the method
The human eye is not designed for consistent color measurement. It is influenced by lighting conditions, the surrounding environment, fatigue, and even the context in which a color is observed. In other words, it responds to almost everything except objective reality. This is why a familiar scenario occurs: a production batch passes internal quality control without issue, only to be rejected later by the customer. The reason is simple—the product is evaluated under different lighting conditions.
Why Do We Still Rely on Visual Inspection?
Every time you rely on visual assessment, you increase the risk of customer complaints, lose control over consistency, and leave room for subjective decision-making. Subjective decisions simply cannot be standardized or scaled.
Modern spectrophotometers are remarkably easy to use. Simply switch on the device, measure the sample, and compare the result with the reference value. If you know how to use a smartphone, you already have the skills to operate this tool.
Conclusion
If your decisions are based on visual impressions, you are not managing quality—you are managing risk. It is time to replace “it looks good” with “it has been verified to be within tolerance.” After all, you are not losing money because of color itself; you are losing it because of the way you control color.
