Its innovative advantages include: a built-in standardized line-type database from major sports associations like FIBA and BWF, supporting one-click application and intelligent adaptation; the use of an environmentally friendly cold-spray process, enabling immediate use after marking with no odor emissions, meeting the stringent requirements of indoor venues; and an intelligent spray gun system that automatically adjusts line width (5–50 cm) and coating thickness, ensuring clear, uniform, and highly durable markings.
