Printing labels

[Dr. Dieter Fiege]

The reason we use pencil instead of ink is that some ink also comes off 
after a while - for what reason we do not know (quality?). Sure, we have 
labels written in ink more than 100 years old and still very clear. The same 
is, however, true for pencil. And even if the pencil fades out you can read it 
- dried - under a UV-lamp.
