Series 1996 $100 Printed Fold With Ink Ghosting

Nice example!

Thanks all for taking a look. A couple additional comments.

The printing of this series of notes I believe used what are called 32 subject sheets, that is 32 notes per sheet. The sheets are organized in four quadrants of 8 notes each A1-H1, A2-H2 and so on. The note designated H4 is positioned at the lower right corner of the sheet. Also, I believe that things like the serial numbers and seal are printed later in the process and in this case were printed after the fold occurred.

When I say that printed fold errors are common I mean that they are a more common type of error not that errors themselves are common. At least that is what I've read.

How the "ghosting" happened is a mystery to me. I'm hoping someone more familiar with the whole process will have an idea.

That is known as an offset. It occurs when the ink is not completely
dry when the sheets are stacked during printing.
lahave56 is correct when he said the number and seal was printed
after the sheet had folded. These are printed on a second press
after the initial printing of the design.

Do not take this to the bank, there is a premium for such an error.
