Overview

Bar Code Discovery lets you create and manage bar code templates to specify the location and type of bar code that users will frequently scan. Other applications such as Scan to Network Premium can then access these templates to reduce the amount of time it takes to scan and identify bar codes on a given scanner.

This application supports the following bar code types:

• Code 11

• Code 128

• Code 32

• Code 39

• Code 93

• Codabar

• Data Matrix

• EAN-13

• EAN-13 plus 2

• EAN-13 plus 5

• EAN-8

• EAN-8 plus 2

• EAN-8 plus 5

• Interleaved 2 of 5

• ITF-14

• Patch Code

• PDF 417

• Planet

• PostNet

• QR

• RM4SCC

• RSS-14

• RSS Limited

• Telepen

• UPC A

• UPC A plus 2

• UPC A plus 5

• UPC E

• UPC E plus 2

• UPC E plus 5

Optimizing bar code detection

Tips on scanning bar codes

• When scanning one-dimensional bar codes, position them horizontally to match the linear scaling of the bars.

• If patterns of text and specks are falsely detected as bar codes, then you can choose to ignore those areas, or you

can rescan the page.

• If the bar code is skewed on the page itself, then position the page in such a way that the bar code is aligned

horizontally or vertically with the scanner. This is particularly helpful when scanning two-dimensional bar codes, such as PDF417, Data Matrix, and QR codes, which are harder to recognize than basic one-dimensional bar codes, such as Code 3 of 9 and Code 128.

Tips on designing bar codes

• Increase the bar code font size to a more readable size.

• Make sure asterisks appear before and after the bar code characters. Asterisks are used as start/stop characters

for most linear bar codes.

• Make sure that only valid bar code characters are used within the data. An invalid character may be recognized as

a blank space, which will then result to having increased gaps between the bars.

• Make sure that there is enough contrast between the bar code and the color of the material you are printing on.

• Make sure to know the type, resolution, orientation, placement, and the number of bar codes on a document.

These are significant factors that can affect bar code detection.

• To prevent patterns of text and specks from appearing as bar codes in some documents, make sure to establish a

quiet zone (a clear area without any text or other marks) around the bar code.
