The reason why inspecting color unevenness and shade variation is difficult.
Reasons and Approaches for the Difficulty of Inspecting Color Variations and Shade Variations
Color variations and gradation inconsistencies do not have clear boundaries like scratches or chips. People assess the gently changing shades based on the angle of view and the lighting. To inspect images, it is necessary to maintain consistent lighting and convert the variations into numerical values. The process of converting the limit samples into numbers determines the success or failure of the inspection. [Key Points] ■ Variations have no boundaries, making it difficult to draw a standard line. ■ The appearance changes depending on the lighting and viewing angle, so conditions are fixed. ■ Measure the limit samples and convert them into numerical standards. *For detailed explanations, please refer to the technical notes and downloadable materials in the related links.
