Wikipedia - Non-photo blue
"The difference between the non-photo blue and black ink is vast enough that digital image manipulation can separate the two easily."

"There is no known colour within the Pantone Matching System that matches non-photo blue."

I didn't invent this. I saw it somewhere.

A student went to a copy shop to print some materials. He wanted to print 2 copies. Somehow, instead of printing out 2 copies, he printed every pages twice. Let me illustrate.

Pages he wanted : 1 2 3 4 … N; 1 2 3 4 … N

Pages he got: 1 1 2 2 3 3 4 4 …. N N

So when he was trying to sort the pages by picking up one and putting on the left pile and then picking another and putting on the right pile, the owner of the shop took over.

He first put the first page on left and then picked 2 pages and put on the right, then 2 left, 2 right ……

Sorting speed doubled……

Xerox scanners/photocopiers randomly alter numbers in scanned documents · D. Kriesel
[[* How many incorrect documents (even though they look correct!) did I produce during the last years by scanning with xerox machines? Did I even give them to others?
* What dangers are imposed by such possible document errors? Is there a danger of life for someone?
* Can I be sued for such errors?

2014-Aug-12: Xerox scanning issue fully confirmed. They indeed implemented a software bug, eight years ago, and indeed, numbers could be mangled across all compression modes. They have to roll out a patch for hundreds of thousands of devices world-wide. On one hand, the implications might be of vital significance for Xerox now.

2015-March The German Federal Office for Safety in Information Technology bans JBIG2 from being used for archival purposes.

Void pantograph
Void pantographs work by exploiting the limitations and features of copying equipment. A scanner or photocopier will act as a low-pass filter on the original image, blurring edges slightly. It will also not be perfectly aligned with the directions of the document, causing aliasing. Features smaller than the resolution will also not be reproduced. In addition, human vision is sensitive to luminance contrast ratio. This means that if a grey region consists of a grid of very small dark dots the filtering will produce a lighter grey, while a region of larger dots will be affected differently ("big-dot-little-dot"). This makes it possible to see a pattern that previously was invisible.

The limits of the digital humanities, by Adam Kirsch | New Republic
There is no room for Bartlebys in the twenty-first century, and if a few still exist they are scorned. (Bartleby himself was scorned, which was the whole point of his preferring not to.)
