Here’s what’s weird. IF they scanned in the original and then printed it on the security paper and stopped there, there would be no white around the text. Most printers don’t have white ink. Any white in the original would simply show up as the green/yellow background on the paper. They must have digitally added the white later to make it more legible. I believe this is legit, but they aren’t doing themselves any favors by digitally altering the document (even if just to make it more legible).
