Signature Capture

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.
Figure 31 CapCode Structure
The separator spaces on either side of the signature capture box can be between 1X and 3X wide.
Start / Stop Patterns
Table 44 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.
Table 45 lists selectable parameters used to generate the image of the captured signature.
