What is the fade resistance of the thermal paper?
The coating used to manufacture thermal paper is slightly sensitive to ultraviolet (UV) light and may exhibit some image decline with extended exposure to office light or shorter exposure to intense UV light. The stability of the image will depend on the degree to which the image was originally developed, the individual product design, the intensitvity of the UV light and the character of the UV (percent of UV range and light source). Sheet discoloration may also occur with prolonged exposure to UV light.
