The oversaturation of red is a give away.
Cheap scanners tend to have lower color gamuts.
Also cheap printers even up to medium priced printers $7,000-10,000
will have a lower color gamut and will produce prints like that fake
marquee.
The red is oversaturated because the printer can only produce a limited
amout of color so it will print red instead of...
orange , yellow , ETC.
Another indicator is the correct size.
Look at the actual size difference between the real and the fake.
Knowing the correct dimensions for a real marquee will eliminate some fakes.
