Soon, the Voiron house will start selling a special kind of paper. Despite its normal appearance and format, its peculiarity is that it is not possible to photocopy what is written in this paper.

This paper, invented by the Canadian house Nocopi, is covered with reddish ink. This ink, when the paper is placed in front of the photocopier lamp, absorbs the light surrounding the text. This role is very appropriate when confidential information is not intended to be duplicated. The protection, of course, is not total, since you can copy the text manually or photographically.

This role is on sale in the US and will be in France soon. The pack of 250 DIN A 4 will cost about 160 pounds, that is, 0.64 pounds or 13 pesetas. page page page page page
