Default Re: February 4, 2018: Where Do PDFs Come From?

Smarsh missed one I've seen used by some companies: instead of using OCR software on old books, just scan each page as an image. Then, in a hidden layer, put in any important words that appear on the page so someone can "search" and it'll go to the correct page, but you can't actually copy the text. This is a terrible thing to do, mind, but it is done.
