Solved! Is there ink or paper can't be picture or taking by mobile camera

Solution
If I understand your question properly, "Is there a technology, printer ink, or printer paper, which will prevent taking a photo of with a camera"?

My (uneducated) reply would be, "even if there is, it is not widely available". If it has to be seen by a naked eye, it will be seen by a camera, too.
