Debossment and embossment

6-20
Debossment is the depression of the paper surface caused by
printing pressure. It is commonly associated with letterpress and
impact printing technologies, and is not produced by xerographic
printing. However, when the bank adds the amount to the
Amount field, unacceptable debossment could result at that
point.
The maximum depression allowed is 0.010 inch/0.03 mm. The
amount of debossment is determined by measuring the distance
between the lowest point of each encoded character and the
maximum reading obtained from the surrounding paper within
that character space on the same horizontal plane.
Embossment refers to an image extending above the surface of
the paper. This can occur in xerographic printing as well as in
letterpress and impact printing.
The maximum allowable embossment is 0.0006 inches/0.02
mm. The amount of embossment is determined by measuring
the distance between the highest point of each encoded
character and the minimum reading obtained from the
surrounding paper within that character space on the same
horizontal plane.
