The front is a dark green/blue tint over most of it, but the back is normal. It's hard to see in the large pictures, but the closeup of the 1 shows more of the actual color. IS this from being over inked, or some other issue after printing? Wet and bleeding ink? I'm not real familiar with paper errors.
There are errors that are "ink smears" which are often faked. Your type of note can often be an offset ink transfer, when the note touches the bed and picks up the reverse on the obverse. But in my opinion, this particular note in your photo, looks like it has been through a washing machine in a jeans pocket.
Thanks. That's what I was thinking also. The one thing that is different is, wouldn't the back side also get this effect maybe in a lesser amount? or if it was folded then it just transfer onto the folder sides? Again, thanks.
Possibly could have even got wet in a wallet with something else, like a store receipt or business card, maybe the person was sweating, sat in something wet.
Very true! And looking closer, the fold marks are darker than the rest. SO, yes, I agree it was wet and had something transferred on it. To learn something: is there a way to tell if it is from the printing? Thanks @tommyc03.
I probably could not word it correctly, but the BEP site does have some interesting information and I believe, some videos about parts of the process of printing notes. In many cases improper transfer of ink is/can be caused by a faulty "Wiper" blade that crosses back and forth against the print cylinder. It is very thin and extremely sharp and if not checked often enough, can get nicks in it that allow this to happen. We had the same problem in printing barrels for hypodermic syringes where I worked. They were referred to as "Doctor" blades. Even though the base for the ink is a pure as it can be, it has to be diluted to get the proper consistency to print properly and sometime stray foreign matter can get into the pumps that can cause these blades to get nicked. This is almost always the cause for ink smears and other spots. The alignment of the blade to the cylinder is extremely precise so as not to damage the cylinder.
Sweat and Blue Jean Dye... I've seen it happen when I left a Bill in my pocket and washing in hot water.
