[Nhcoll-l] vanishing ink

Tue Jul 2 07:02:38 EDT 2013

We try with a hand held uv lamp then a large tube and it works fine (see attached file)
A good photo and a little photoshop will definitely fix the problem I guess.

Old pencil labels need rather a bright light with different angles as far as I tried. 

Many thanks for your help
