Like other 1D barcodes, Code 39 labels can be easily corrupted and become unreadable as a result of ink spread while printing. Use the CGI form below to generate a printable and scan-able barcode in Interleaved 2 of 5, Code 39, Code 128 A, B, or C symbologies. Code 39 is not applicable in situations when space limitations are critical. Low data density means that the greater is the amount of information to be encoded, the larger is the size of a barcode label. Main limitations of this type are quite low data density and inability to verify the correctness of recognition as it does not include default checksum controls. Such barcodes can be scanned and decoded by most scanners existing in the market. Advantages and LimitationsĬode 39 can be applied to the majority of industrial needs. It allows adding an optional check digit computed using the modulo 43 algorithm. Checksum ControlsĬode 39 does not require setting obligatory checksum controls and thus does not provide high recognition precision. This happens because symbols from the full ASCII set need to be encoded in two digits and thus occupy a larger space. Even though it enables encoding the entire ASCII set including 128 symbols, this leads to limitations in terms of density. Encoding Capacity and Data DensityĬode 39 allows generating barcodes of variable length its average data capacity varies from 20 to 23 alphanumerical characters. The larger is the selected proportion, the larger gets the printed label however, this also improves readability. This standard allows generating labels of different proportions, i.e. The size of quiet zones should be 10 times wider than the current X-dimension. To scan Code 38 barcodes manually, it is recommended to set the minimum height to 5.0 mm or 15% of the width. One-module wide spaces separating symbols within a barcode.One or more pairs of characters (an optional check digit may be added).Barcode StructureĮach Code 39 data symbol is encoded using five bars and four spaces so that three of them are wide and six are narrow. Der Code 39-Barcode, auch bekannt als Code 3 of 9 oder Code 3/9, ist eine Art von linearem Barcode, der eine Kombination von Strichen und Leerzeichen zur Darstellung von Daten verwendet. Symbol ' * ' serves to denote start and stop digits. Characteristics Encoding Character SetĬode 39 enables encoding characters from the 43-character and 128-character ASCII sets, including uppercase English letters, numerical digits, and special symbols (space, ‘.’, ‘-’, ‘/’, ‘%’, ‘+’, ' * ‘, and ‘$’). LOGMARS), healthcare sector, transportation, and assembly tracking. It was widely implemented in various applications, such as inventory management, digitalization of name badges, automotive and medical equipment production, airplane construction, defense projects (i.e. You can find additional information of classes and properties that are used in Aspose.BarCode for linear barcode generation and recognition:ĭespite being introduced in the mid-’70s, Code 39 remains one of the frequently widely used barcode types even nowadays.
