uv fluorescent pigment rau anti-falsification printing
Taw qhia
UV fluorescent ximNws tus kheej tsis muaj xim, thiab tom qab nqus lub zog ntawm lub teeb ultraviolet (uv-365nm lossis uv-254nm), nws tawm sai sai thiab nthuav tawm cov xim zoo nkauj fluorescent.Thaum lub teeb pom kev raug tshem tawm, nws nres tam sim ntawd thiab rov qab mus rau qhov qub tsis pom.
