![]() ![]() This code set is numeric-only, but any one character actually represents two digits. Do not use ordinary Code 128 to encode GS1. All of these names effectively mean the same, GS1-128. ITF is a barcode with an extremely high information density, and it has the. The three character code sets can be summarized as follows:Ĭode Set A: Includes all numeric values (0-9), uppercase alphabetic characters (A-Z), punctuation marks, seven special characters, and "control" characters (ASCII values 00 through 95).Ĭode Set B: Includes all numeric values (0-9), uppercase and lowercase alphabetic characters (A-Z, a-z), punctuation marks, and seven special characters (ASCII values 32 through 127).Ĭode Set C: Includes all numeric digit pairs from 00 through 99 and three special characters. The variant is now known as GS1-128 but because GS1 was known by different names throughout its history the previous names of the variant will still be found in software and literature. Code 128 Barcode is a high-density linear symbology that encodes text, numbers, numerous functions and the entire 128 ASCII character set (from ASCII 0 to. The most common use of Code 128 is for certain shipping labels, primarily as defined by the Uniform Code Council in their UCC-128 shipping container bar coding standard. Because of this, Code 128 gives you the greatest possible character density when encoding data. Code 128 not only gives you the ability to encode all 128 ASCII characters, when encoding numbers only, it can actually encode them more densely than Interleaved 2-of-5. ![]() However, it is possible to switch between the different character sets and use any combination of them in a single symbol. The Code 128 barcode is a high-density linear symbology that encodes text, numbers, numerous functions and the entire 128 ASCII character set (from ASCII 0 to ASCII 128. The default code set that is in use for any Code 128 barcode is determined by the start character. GS1 Code 128, and PDF417)) with different data densities are presented as. This is possible because Code 128 uses three different sets of 102 characters: Code Set A, Code Set B, and Code Set C. Description of Various Barcode Types Supported in Aspose. The start character that will be used for a given barcode depends on what characters need to be encoded in that portion of the barcode.Īlthough a Code 128 character set itself contains only 102 characters, this symbology supports all 128 lower ASCII characters. Start character: Code 128 has three different start characters, one for each of the three character code sets: Code Set A, Code Set B, and Code Set C. Also, unlike UPC/EAN, Code 128 is not limited to numbers only. Although this represents a 50 percent reduction in character density, Code 128 can represent all 128 ASCII characters. However, whereas the UPC/EAN family uses four elements (two bars and two spaces) per character, each Code 128 character is represented by six elements (three bars and three spaces). Symbol characters: Most barcode symbologies print bars and spaces in only two widths (wide and narrow), but Code 128 uses four different widths, as the UPC/EAN family does. Download the generated barcode as bitmap or vector image. This code set is numeric-only, but any one character actually represents two digits.The symbol comprises the following elements: Also, a quiet zone of at least ten times the X-dimension (width of a narrow bar) must be maintained at either end of the symbol: The quiet zone should be considered an integral part of the Code 128 symbol as show by the above image. Free GS1-128 (UCC/EAN-128) Generator: This free online barcode generator creates all 1D and 2D barcodes. Bar Height/Length The bar dimension perpendicular to the bar width. Barcode Density The maximum number of characters that can be represented in a linear unit of measure, which is often written as characters per inch or CPI. The three character code sets can be summarized as follows:Ĭode Set A: Includes all numeric values (0-9), uppercase alphabetic characters (A-Z), punctuation marks, seven special characters, and "control" characters (ASCII values 00 through 95).Ĭode Set B: Includes all numeric values (0-9), uppercase and lowercase alphabetic characters (A-Z, a-z), punctuation marks, and seven special characters (ASCII values 32 through 127).Ĭode Set C: Includes all numeric digit pairs from 00 through 99 and three special characters. The barcode character is the smallest part of a symbol that holds data. Therefore, GS1-128 gives you the greatest possible character density when encoding data. However, it is possible to switch between the different character sets and use any combination of them in a single symbol. The default code set that is used for any GS1-128 barcode is determined by the start character. This is possible because GS1-128 uses three different sets of 102 characters: Code Set A, Code Set B, and Code Set C. The PDF417 barcode is a two-dimensional (2D), high-density symbology. Although a GS1-128 character set itself contains only 102 characters, this symbology supports all 128 lower ASCII characters.
