The fluorescence performance of red water-based fluorescent screen printing ink was studied by changing the content of red fluorescent material. Based on that, the color gamut of red, green and blue fluorescent ink was obtained. The effects of different coloration methods on the fluorescence performance of three-color ink were compared and the ef- fects of two different substrates on the coloration performance of three-color ink were investigated. When the phosphor content was 6%, the fluorescence intensity of red water-based fluorescent screen printing ink was the best. The color ga- mut range of three-color fluorescent i
