Its a long-term dream of mine to publish a mentalism effect (a challenge for me because I'm not very good at designing new mentalism material), and while this probably will never happen, I did start wondering about how I would protect the secrets of the effect.
For example, I read recently on TheMagicCafe that if your text is printed on dark green paper, then it cannot be scanned and copied to a computer, therefore making it harder to publish on the internet. Does anyone know if this is true?
It makes me wonder how someone would go about protecting magical secrets in this day and age, here is a short list of things I think help keep the secrets - and hopefully we can expand on it

1. Price Tag: If the price tag is high enough, it will stop "casual" people from buying the effect just to find out how it is done.
2. Limited edition: If a manuscript of gimmick is unique of rare, it is unlikely people are going to give away the secrets.
3. Asking nicely: If you write "Remember the Magicians Code, audiences love mystery" or something equally nice and friendly inside each manuscript, it discourages people from exposing the method.
4. Patent: This can work both ways, it means the effect cannot be copied (so the masked magician cannot expose it), but it also means that somewhere there is a public patent with the method on it. What do people think of this?
5. Green paper: Printing on special paper can make it harder to copy, you could also laminate it to make it unphotocopyable (?).
6. No Ebook: Any writing that is published only in print, and not online is much less likely to be exposed.
7. Mirror writing: This is boarding on the paranoid and rediclous, but mirror writing would make it harder still to photocopy - though harder to read. Still worth mentioning though; hats of to Da Vinci.
Any other ideas?
