Code 128 ist eine Barcode-Symbologie mit hoher Dichte, die die Codierung von Zahlen- und Zeichendaten ermöglicht. Es bietet die Möglichkeit, 128 ASCII-Zeichen zu codieren. Es enthält eine Prüfziffer zur Verifizierung und verifiziert Zeichen für Zeichen.
Der Code 128-Barcode wurde in zahlreichen Anwendungen eingesetzt, in denen große Datenmengen codiert werden müssen, darunter 0–9-Ziffern, A–Z-Buchstaben und alle Standard-ASCII-Symbole und Steuercodes. Code 128 ist in drei Teilmengen unterteilt: SET A, SET B und SET C.
Code 128 SET C Barcode Font enthält nur numerische Daten. Mit dem Barcode Maker-Tool können Sie ganz einfach Barcode-Schriftbilder mit bestimmten Werten, Kopf- und Fußzeilen, Größen, Schriftarten usw. erstellen. Die Software verfügt über eine Druckoption zum Drucken der entworfenen Barcode-Schriftart Code 128 SET C mit vordefiniertem Etikettenmaterial oder entsprechend im manuellen Modus.
Anwendungsbereich: weit verbreitet in der Versand- und Verpackungsindustrie zur Produktkennzeichnung.

Symbol Structure of Code 128 SET C
- Start character
- Symbolic characters that represent data
- Check character
- Stop character
- Quiet zone
Symbol characters: Most barcode symbologies print bars and spaces at only two widths, wide and narrow, but Code 128 uses four different widths, as does the UPC/EAN. UPC/EAN barcode uses four elements—two bars and two spaces—per character, each Code 128 character is represented by six elements—three bars and three spaces. Despite the 50% reduction in character density, Code 128 can represent all 128 ASCII characters. Also, unlike UPC and EAN, Code 128 is not limited to numbers only.
Start character: Code 128 has three different start characters, one for each of the three character code sets, such as Code Set A, Code Set B, and Code Set C. 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.
Features of Code 128 SET C
- Supports all types of characters.
- It allows the barcode to be as small as possible for an indication with only numeric values. (More than 12 digits).
- Begins to be used as GS1-128 in each industry, such as distribution business, food industry, medical industry, and so on.
- It can store almost all the special characters.
- Code 128 increases data security for encoded data and reduces the possibility of scanning errors.
- It is compact and can store a large amount of data in a small amount of space.
- It is widely used in combination with code 39 in all advanced brick-and-mortar companies.
Limitations of Code 128 SET C
- The most advanced scanners are required to scan these Code 128 barcodes.
- Code 128 is very challenging to print because it contains four distinct width variants for each character.
- Code 128 utilizes four different bar sizes, and therefore, it requires high-quality printers to print out labels such as Dot matrix and ink-jet printers. Flexographic printing on corrugated cardboard is not supported either.
- It has four different width variations for each encoded character, so it is not easy to print a barcode.
