It’s actually a forgery/counterfeit detector — most copy machines can’t reproduce the microprint and it comes out as just a solid line. If you use a strong magnifying glass, you’ll be able to determine whether the line is microprint or if it’s just a solid line. So — the solid line means the check was likely made on a photocopier or printer, and the microprint likely means the check is authentic.
I just finished watching a great movie tonight.
It’s called “The Counterfeiters”. It is about “Operation Berhard”, the Nazi plan to flood England with counterfeit Bank of England Notes to destabilize their economy.
During the movie, my Mother turned to me and said “That’s what Obama is doing to Us now.”
I highly recommend this movie to this audience.
