 Professional visual color assessment

 

Why is a standard light source box needed?

Printing standardization has become the most effective way for printing and packaging companies to improve efficiency and quality. In the process of achieving standardization, a standard light source can help accomplish crucial color selection and reliable color evaluation, avoiding unnecessary modifications. By using a standard light source to visually assess different items side by side under various lighting conditions, it helps identify product defects, color inconsistencies, metamerism (an optical phenomenon where two samples match under one light source but not under another), and the effects of optical brighteners (OBA).

A standard light source can reproduce multiple lighting environments, including daylight (D50, D65), incandescent light, warm white fluorescent light, and LED light, ensuring that the product's appearance is accurate in retail stores and when it reaches consumers in factories, homes, or offices. It helps users adhere to the visual assessment requirements of mainstream international standards, including ASTM, DIN, ANSI, BSI, TAPPI, and ISO.
