We have still not, as far as I know, learned what the governments threatened the manufacturers with or what they offered to them in order to get them to cooperate.
Reasons why it's laser and not inkjet:
- Crisp edges on fine details
- Consistent colors
- Consistent alignment
Remeber, we're talking about "EURion constellation" that was in use at least since 1996. Also, remeber we're talking about regular consumer printers: consumer laser printers > consumer inkjet. I guess also remember that not ever banknote is a US dolar?
That's a different measure! It's detected by some software in photocopiers or software used in conjunction with scanners, not produced by printers.
The other reason I had thought why inkjets were considered a lesser concern for counterfeiting is that the documents they produce will traditionally smear if they get wet, which doesn't seem like a very desirable property in counterfeit currency and documents. Maybe over time they've tended to use more permanent inks, though.
