How to protect header and on.... paper?

Hi everybody,

I have setup a my FDE using LUKS, and tying the decryption key to my 
TPM+recovery key. Now I am wondering: I know I can get a backup of the 
LUKS header on a file, store it somewhere and done... but what happens 
if the USB is corrupted by the time I need it? what if I put it on an 
optical disk and has been scratched? This kept me thinking: is there any 
possibility/process to have the required information for the header 
printed on paper, that could be stored on a safe?

Thank you very much for your time,
