Make OCR on text impossible.

Question

I am looking for a way to make text not readable via OCR. I was wondering if there are any techniques that are good for this. To be clear on an 8.5 x 11 page I want to create a printed document that a human can read. However, if the document is inserted into a scanning device (copier, scanner, etc.) I do not want the result to produce readable text. I also need it to be as close to the size of business letter text as possible. I was thinking there could be a way to dither the text so that would confuse the scanning device. I also wonder if I could cover it with a film, or any other method. The only thing necessary is that a human can read the text. Any suggestions are welcome. Thanks

pctechtv,

My first thoughts were that yoou could try with differently coloured dots which can however hit folk with different kinds of colour blindness (they might appear much like colour blindness tests), or with distressed text which can however distress many/all readers.

It may very well be a hopeless endeavour, like locked/uneditable artwork.
