目的 为了更好地研究加色法成像机理，改善红色水性荧光丝印油墨的荧光性能，进而对三色荧光油墨的呈色性能进行研究。方法 通过改变不同红色荧光材料的含量研究红色水性荧光丝印油墨的荧光性能，接着在此基础上，得出红、绿、蓝三色荧光油墨的色域，比较不同呈色方式对三色油墨荧光性能的影响，并探讨2种不同的承印物对三色油墨呈色性能的影响。结果 当荧光粉质量分数为6%时，红色水性丝印荧光油墨的荧光强度最好。三色荧光油墨的色域范围比sRGB范围略小，可以满足色彩再现的研究需要。丝印时，网点并列比网点叠合更有利于荧光油墨彩色信息的真实再现。不含荧光剂的承印物有利于荧光油墨的色彩再现，纸张比pc膜色调再现能力好。结论 最终制备的水性丝印荧光油墨具备优良的荧光性能，可以再现sRGB色域内的大部分色彩。

The work aims to better study the imaging mechanism of the additive color method, improve the fluorescence performance of the red fluorescent screen printing ink, and then study the coloration performance of the three-color fluorescent ink. 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 effects 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 gamut range of three-color fluorescent ink was smaller than sRGB, but it could meet the needs of color reproduction research. For screen printing, compared with dot superposition, the dot coordination was more favorable to the true representation of fluorescent ink color information. The substrate containing no fluorescent agent was in favor of color reproduction of the fluorescent ink. The paper was better than PC film in hue reproduction ability. The water-based fluorescent screen printing ink finally prepared has excellent fluorescence performance and can reproduce most of the colors in sRGB color gamut.
