Glow powder, technically known as photoluminescent powder, absorbs light and slowly releases it to create the Glow in the Dark option.
Therefore, it can be charged with any light source such as a light bulb or the sun
When put in a very dark area, it will glow for a limited time
The appearance of the glow in the dark ink, seen under day light, is light yellow.
In a very dark area, it gleams with a bright yellow/green color.
The lighter must be in a very dark place, the fastest as possible after beeing exposed to light, in order to function properly
This option is not applicable on thin designs and dark colors. A 1cm2 minimum surface is recommended, and colors should not be darker than an equivalent to BLACK 20 %.
