Print a PDF417 barcode symbol with exactly 10 rows.

Images and symbol sizes may differ slightly with various screen resolutions and printers. Consequently, it may be necessary to check the X or Y dimensions. Measuring X & Y Dimensions of a Printed Barcodeīarcode products generate images according to the pixels of the target device thereby creating an image difference. A few of the guides offered include the following: These options may be examined to determine the best implementation method. Barcode Integration Guides are also available that offer one or more integration options. IDAutomation also offers new patent-pending Native Barcode Generators for JavaScript, Crystal Reports and Microsoft Access that create PDF417 without any plug-ins or fonts. All of our PDF417 products were created from ISO/IEC 15438. The IDAutomation PDF417 Barcode Font and Encoder is a collection of encoders and components that generate PDF417 symbols as graphics or as a font. This option should be used primarily in a clean environment, since it is more susceptible to damage. By selecting this option, the right hand side of the symbol is removed or truncated.

A truncated PDF417 symbol uses less area than the normal PDF417 barcode.

Some scanners and decoders cannot dependably read over 20 columns. Truncated PDF417 contains only two row start columns. The normal PDF417 barcode symbol has two row start columns and two row stop columns. Keep in mind when selecting columns, only the number of data columns in the symbol are being selected. However, the PDF417 barcode symbol is limited to 30 columns and 90 rows.

The number of rows and columns can be selected, allowing the symbol to be created in various forms.When creating symbols with more than 10 columns, IDAutomation recommends using a ratio of 1:4 or 1:5. Most scanners, such as the IDAutomation PDF417 2D USB Scanner, read PDF417 barcodes well at 1:3. By lowering the ratio, a significant amount of space can be saved however, some scanners cannot read X to Y ratios of less than 1:3. The PDF417 barcode is usually printed at an X to Y ratio of 1:2 to 1:5, with 1:3 being the most popular. The Y dimension is the height of each row within the PDF417 symbol. The X dimension is the width of the narrowest bar in a printed codeword.The chart below indicates the number of error correction codewords that are added to the printed symbol and AIM recommendations for the EC level.įig. The error correction levels range from 0 to 8. The error correction level depends on the amount of data that needs to be encoded, the size and the amount of symbol damage that could occur. AIM standards recommend a minimum error correction level of 2. This error correction allows the symbol to endure some damage without causing loss of data. PDF417 uses Reed Solomon error correction instead of check digits. Because the codewords in each cluster are unique, the scanner is able to determine what line each cluster is from. A different cluster is chosen for each row, repeating after every three rows. Each codeword represents 1 of 929 possible values from one of three different clusters. The printed symbol consists of several linear rows of stacked codewords. Large amounts of text and data can be stored securely and inexpensively when using the PDF417 barcode symbology.
