Printed wallet QR codes extra security

[btcluck]

Hi guys,

Just registered but long time with bitcointalk because I have idea and I want to share with all of you:

How about making printed wallets easy for use, increase their use but also to add extra security on the all process.

Check my idea that now it's on realization ( yup I create the prototype software and DYI kit )  : http://btcluck.blogspot.com/2013/12/private-key-qr-extra-protection.html

Edit:
I have performed tests with some materials and results are just perfect: http://btcluck.blogspot.com/2013/12/secure-printed-wallet-poc-experiment-2.html 

I want to know your toughs about this.

Good idea. But you should:

1. Printout in high-definition
2. Keep multiple backup
3. Use your own printer

Def. using your own equipment. Also this library ( probably JS for easy starting on every machine ) would allow option to create one master pattern for the user and based on that pattern user can print many printed wallets.
