Why fluorescent ink looks fluorescent
As can be seen from being a highlighter when expressed in English, it is possible to show the color more vividly by converting the light by sunlight and illumination to the wavelength of a certain light. In our company, we have developed the use of this feature, and sent it to the world as a memorization pen. Other characteristics are the tendency of the pigment making of the ink and the tendency of the OA correspondence.
Naturally, the fluorescence does not glow if the light does not hit it. The black Light (UV lamp) produces light with a strong energy that is invisible to the eyes, so that only the fluorescent surface develops very vividly. In our company, there is a characteristic as a color that other companies do not have a bright yellow color.
