I am looking for a substance that will react to intense light, such as that found in a scanner, to see if it is plausible to make a form of Ink or paper which could help stop people simply scanning and re-printing photographs bought off a relative of mine. Silver Nitrate is my first candidate, but seems too sensitive, hence the question. Any other useful substances would be equally appreciated.
Re: Is it possible/easy to make Silver Nitrate less sensitive?
