The determination of how photoluminescent pigment will be used generally has to do with the size and effort involved in the application. A large sample of photoluminescent pigmentation involves the utilization of a relatively large particle size that powdered paint pigments will provide a very high afterglow intensity that is considered suitable for most types of applications, of which includes both brush and spray painting, glass molding, and candle making. What is considered as a medium size application – which only needs a relatively moderate size of particles and what will emit a moderate afterglow intensity – would be suitable for applications such as silkscreen printing and plastic molding. A small, or fine size pigmentation level, which requires only a small particle size (a fraction of the large quantities) and low afterglow intensity, can be used for thread and fiber production, or virtually any type of production process that requires very fine article sizes.
