I thought that List members might be interested in the following extract from an article published in the current month's issue of GRAFIX, the trade magazine of the graphical design industry. ------ Headlined 'An end to photocopying' the article describes the development of a new type of printing ink which is aimed at foiling the unauthorised copying of copyright material. A new ink has been developed which instead of pigments uses microscopic beads of a polymer. Polymers in general are photo-sensitive and react in various ways when exposed to light, it is possible to tune this sensitivity to a particular wavelength, in this case the light from the Xenon ion discharge tube used in modern photocopiers. The normal light absorbing property of the beads, which makes them appear black against a white background, is changed to reflecting and the image becomes translucent. A single pass through a copier will reduce the opacity to 25 percent. The image can still be seen under a good light but for normal purposes it is unreadable. At present the new inks can only be used with the Offset Litho process. This is the process used for short print runs of specialised material such as sheet music. A spokeswoman for Studio Litho said, " The prevalence of photocopying has been a problem for the music printing industry for some time particularly in the area of Educational music and music for School Orchestra, Wind Bands and Brass Bands. The industry is loosing a large amount of revenue to this practise. We have successfully prosecuted one peripatetic music teacher who was buying one copy of Grade music and copying it for all his pupils, in one case eighteen pupils were taking the same Grade, that is seventeen copies that we didn't sell. These inks are being introduced by our company for certain publications from this month. If we receive a complaint that one of our publications has become faint then we will know that an attempt has been made to copy it and will be able to take appropriate action. " ------ So, beware, if you try to copy music printed from today, not only will you not get a copy but you will also lose the original. -- Ed Morris --
