Hand Held Products IT4600 Postal Height-Modulated Bar Code Symbologies, Postnet and Planet Code

{4} X roughly = 0.043"

{5} [A] < Data Safety Margin = 100%

{6} [A] < Horizontal Print Growth = +2% of X {7} [A] < Vertical Print Growth = -1% of X

{1} is the Encoded Message.

{2} is the Banner heading.

{3} identifies the Symbology (MAXICODE) and lists the symbol's Mode.

{4} presents an approximate X-dimension.

Note: The reported X-dimension is approximate and based upon use of the IT4410LR at 4.7 in (12 cm) (see "Reading Techniques" on page 1-1). If you use different image engines, the X-dimension will vary. If you hold the reader closer than 4.7 in (12 cm), it will have the effect of reporting a larger than true X-dimension. Conversely, if you hold the reader farther away than 4.7 in (12 cm), it will have the effect of reporting a smaller than true X-dimension. Please contact HHP Application Support for additional information. Refer to Chapter 3 for contact information.

{5} lists the Data Safety Margin. Because the Error Correction level for Maxi- Code is fixed for each mode, this parameter is just the "Unused Error Cor- rection," and is always between 0 and 100%.

{6} and {7} list the Horizontal & Vertical Print Growths, respectively.

Postal (Height-Modulated) Bar Code Symbologies

This section describes the height-modulated 2-state symbologies, Postnet and Planet Code, used in the United States, as well as the 4-state symbologies used in England, the Netherlands (“KIX”), Canada, Japan, and Australia. All dimen- sions, where listed, are in inches for 2-state symbols and in millimeters for 4- state symbols.
