PDF 417

The PDF417 structure is shown in Figure 18 and described below.

Figure 18.PDF417Structure

Quiet Zone

Both ends of the bar code structure require blank quiet zones. The q uiet

zones must be at least 0.25 inches wide and completely blank to ensure

accurate reading of the start/stop codes and to prevent adjacent bar codes

from overlapping. Be sure to provide sufficient space on the form for the quiet

zones.

Start/Stop Codes

The start/stop codes identify the leading and trailing end of the bar code.

Data Field

PDF417 provides twelve modes to encode data. The first three are pre-

established (the remaining nine are user modes, which can be defined by

users or industry associations according to specific applications):

1. Extended Alphanumeric Compaction mode (EXC). Comprised of four

sub-modes, this mode offers encodation of all printable ASCII characters.

This is the default mode; ASCII Emulation uses shift or latch ch aracters to

enable other modes.

2. Binary/ASCII Plus mode. This offers encodation for all ASCII characters,

printable or not, and binary values.

3. Numeric Compaction mode. This offers encodation for numeric values to

a density of almost 3 digits per code word.

ASCII Emulation will automatically switch between modes to provide t he

smallest encodation for the data.

Security Level

PDF417can detect and correct errors. Each label has 2 code words of error

detection. You can select the error correction capacity based on app lication

needs. Specify a security level in the range of 0 - 8, at the time of p rinting.

PDF417 can also recover from omissions and misdecodes of code words.

Since it requires two code words to recover from a misdecode, one to detect
