BARCODE 128 EOT CODE

Please see this post for the Code 128 bit pattern. Also, a barcode must not be wider than the "reading window" or aperture of a scanner or it won't be scanned.

Note that many barcode scanners or reader apps have soft limits below those numbers.

BARCODE 128 EOT FULL

135mm (click for full size):Ĭode 128 C with 60 digits, module width 0.3mm, total length c. The practical content limit for Code 128 is at 30 characters (large cap and small cap letters) or a maximum of 60 digits (purely numeric code).Ĭode 128 B with 30 characters, module width 0.3mm, total length c. Symbology like QR or Data Matrix with dedicated supportįor non-ASCII or Unicode data might be a better choice.Ĭode 128 is a variable length code, which in principle can encode an arbitrary length of data. However, this feature is not widely supported and cumbersome to use. "á ñ ò") can be encoded in a Code 128 symbolīy using a special character (FNC4), defined for Code 128 A and Code 128 B. In principle non-ASCII characters like German umlauts (e.g. Accented, diacritic characters, emoji with Code 128 Code 128 Auto is not a separate version or subset of the code.

BARCODE 128 EOT SOFTWARE

This is performed by the respective barcode software to minimize the size of the code. When using a Code 128 barcode font in Excel or similar applications, the start and stop characters will be mapped to certain character positions however, the mapping is not standardized and will vary from font to font.Ĭode 128 A start character (bitpattern/widths: 211412, bar-gap-bar-gap-bar-gap, widths add up to 11):Ĭode 128 B start character (widths: 211214):Ĭode 128 C start character (widths: 211232):Ĭode 128 stop character (widths: 311123): Code 128 AutoĬode 128 Auto refers to the automatic selection of the 128 subtype depending on the encoded data. Usually the sub type selection and switching within a symbol is handled by the barcode software thatįor reference we are including the bar patterns of the three start- and the single stop-character here. The code set to use is indicated to the scanner by the start symbol or start character.Īlso available are various mode switching or shift characters to switch from one set to another within a barcode symbol. The code sets differ in compactness and encodable character set.Ĭode 128 A: Partial ASCII set, no lower case, but ASCII control chars (TAB, CR/LF etc.)Ĭode 128 B: Full ASCII set, no ASCII control charsĬode 128 C: Only digits 0-9, encoded in pairs, very compact code

Three different code sets or sub types are defined for Code 128 (namely Code 128 A, Code 128 B, and Code 128 C) that determine how the code is interpreted by the barcode scanner. Code 128 code sets A, B, C and start characters As the code is rather old, the Code 128 specs are freely available online, for example in the Wikipedia article on Code 128.

Printing: Thermal direct, thermal transfer, laser, inkjet, dot-matrixĬode 128 is standardized, the respective document is ISO/IEC 15417:2007, which can be obtained from ISO.

Scanning: CCD / Laser scanners, imagers, scanner apps.

Generators: Stand-alone, barcode fonts, barcode extensions.

Check digit: Modulo 103 (not mandatory but recommended).

Modes: Control characters, alphanumeric, numeric compaction.

Character set: Encodes all 128 characters from ASCII set.

Applications: Warehousing, transport, logistics, retail.

Today, Code 128 is one of the most widely used barcode types, for example for warehouse management, in the transport industry (e.g. A Code 128 barcode symbol can encode letters, digits and control characters (TAB, ENTER etc.) which makes it very versatile and suitable for many applications. Code 128 was developed by Computer Identics in 1981 and has become very popular over the years.
