QR Code Problem?
When it comes to putting the QR codes on coloured paper I have noticed a big potential stumbling point; printers don't print white. This means that the white areas of the QR code will be rendered in whatever colour the paper is because the printer assumes its white. This won't be a problem on lighter papers but may be a concern for darker one's especially blues.

To determine what level of tolerance I need for each colour, I will print a test sheet of each on any colour that may be a problem.
