Product Description
【Scope of Application】:
In industrial production, the same product from different batches often exhibits color differences due to variations in materials, ingredients, or production processes. Although inspectors carefully compare product colors, inconsistent environmental lighting makes the perceived color differ under various lights, making it difficult to judge color deviation. Customers may complain or even return goods if the color difference exceeds acceptable limits during inspection. The standard light source light box allows the evaluation of product color under identical and controlled lighting conditions, effectively solving the problem of color difference caused by non-standard light sources. Suitable for color fastness assessment and evaluation of metamerism in industries such as textiles, dyeing, printing, plastics, pigments, paints, inks, photography, etc.
