ʻO ka puaʻa fluorescent UVʻAʻole waihoʻoluʻu iā ia iho, a ma hope o ka lawe ʻana i ka ikehu o ke kukui ultraviolet (uv-365nm a i ʻole uv-254nm), hoʻokuʻu koke ia i ka ikehu a hōʻike i kahi hopena fluorescent waihoʻoluʻu.Ke wehe ʻia ke kumu kukui, kū koke ia a hoʻi i ke kūlana ʻike ʻole.

A. UV-365nm organik
1. Ka nui o ka ʻāpana: 1-10μm
2. Ke kū'ē wela: ka wela kiʻekiʻe o 200 ℃, kūpono i loko o 200 ℃ ka hana wela kiʻekiʻe.
3. Kaʻina hana: Paʻi pale, paʻi gravure, paʻi pad, lithography, paʻi palapala, uhi, pena…
4. Ka nui i manaʻo ʻia: no ka ʻīnika i hoʻokumu ʻia i ka solvent, pena: 0.1-10% w/w
no ka hoʻopili ʻana i ka plastic, extrusion: 0.01% -0.05% w/w
B. ʻO UV-365nm mea ʻole
1.Particle nui:1-20μm
2.Maikaʻi ka wela wela: ka wela kiʻekiʻe o 600, kūpono no ka hoʻoponopono kiʻekiʻe o nā kaʻina hana.
3. Kaʻina hana: ʻAʻole kūpono no ka lithography, paʻi palapala
4. Ka nui i manaʻo ʻia: no ka wai ma muli o ka wai a me ka solvent based ink, pena: 0.1-10% w/w
no ka hoʻopili ʻana i ka plastic, extrusion: 0.01% -0.05% w/w
