    im not saying this is the answer to it all but is credible.
    most glass has some form of tint or filter in them.
    take a car windscreen…
    we put fluorescent and bright coloured vinyls onto car windscreens and the like. these colours reflect the light, where the exposed glass areas surrounding the vinyl absorb the UV light. the longer the vinyl is on the glass the more uv attack is on the exposed areas. as a result it very slightly lightens the tint of the glass.
    we then remove the vinyl leaving the protected areas that were under the vinyl now exposed. however, the surrounding areas are slightly lighter than those that were beneath the vinyl creating a ghosting effect in the glass.

    hope that makes sense? 😕 :lol1:
