CapCode Pattern Structure
A CapCode pattern structure consists of a start pattern followed by a separator space, a signature capture box,
a second separator space, and then a stop pattern. Assuming that X is the dimension of the thinnest element,
the start and stop patterns each contains 9X total width in 4 bars and 3 spaces. A 7X quiet zone is required to
the left and to the right of the CapCode pattern.

CapCode Structure
The separator spaces on either side of the signature capture box can be between 1X and 3X wide.
Start / Stop Patterns
Table I-1 lists the accepted start / stop patterns. The bar and space widths are expressed as multiples of X. You
must use the same pattern on either side of a signature capture box. The type value is reported with the
captured signature to indicate the purpose of the signature captured.
