Or a digital camera + contrast enhancement in Photoshop or the like.

Good luck!

Dear colleagues

We are making an inventory of a fruit collection (jars from 1900-1905) which 
external labels have turned yellow (in fact brown) ; some are illegible.
Is there a way to reveal the faded ink ?  (chimical or light based)

Thanks a lot
