. ・When CODE-C is used, 2-digits numbers can be represented by one type of bar pattern. This allows the very high data density. ・When code set characters (CODE-A, CODE-B and CODE-C) are used, the barcode started with the start character of CODE-A can be changed to use the characters in the CODE-B or CODE-C column in the middle of barcode processing.
・When 'SHIFT' is used, only one character next to the SHIFT can be changed to the character in the next column (A to B, B to C, C to A). (Similar to the SHIFT key operation of on the computer keyboard). ・'Modulus 103' is used as a check digit. ・CODE 128 barcode can include all 128 ASCII code characters (including control codes such as ESC, STX, ETX, CR and LF). ・When CODE-C is used as the start character, one bar pattern can represent 2-digits numbers.
This allows very efficient barcode composition. If the barcode data has 12 or more digits, CODE 128 provides smaller size than ITF. ・Since CODE 128 uses 4 types of bar size, printers with high print quality are required. CODE 128 is not suitable for printing with dot matrix printers and FA ink-jet printers and for flexographic printing on corrugated cardboards.CODE 128 ApplicationsUse of CODE-C as the start code allows CODE 128 to provide the barcode with very high data density, if only numbers are handled.GS1-128 makes use of the characteristics of CODE 128 and is currently used in many industrial applications. With GS1-128, various data are included in the barcode, such as manufacturing date of the product, open date, weight, size, lot number, destination, customer's account, etc.CODE 128 is used in the following industries:・ U.S.A.
Vt Transaction Software
Apparel industry・ U.S.A. Food process industry・ U.S.A. Drugs and medical equipment industry・ Food industries in Australia and New Zealand・ European drugs and medical instruments industryGS1-128 What Is GS1-128?GS1-128 is the barcode that provides various data including distribution and business transaction data in addition to the data provided by the JAN code and the standard distribution code (ITF) currently available.Following data can be included in GS1-128 barcode. ・Package number・Quantity in package・Weight, capacity and cubic capacity・Manufacturing date and validity of quality・Lot number・Location number (destination)・Customer's account code・Customer's order numberNecessary data is used to form the barcode label for the various applications.For example, On-line purchasing/ordering using EDI (the system for exchanging electronic data between companies), management of open date for foods, management of drugs validity, simplifying the work for checking incoming products, sorting packages for every destination, etc. (The following label is a sample from a food manufacturer.). Although application identifiers are parenthesized, the parentheses are not included in the barcode data. They are used just for presentation.In the sample above, following the application identifier '01', 14-digits code is assigned to identify the delivery container (minimum package unit for corrugated cardboard boxes).
Following the application identifier '15', the data representing the validity of quality (consumption validity or drug validity) is given to show August 27, '95. Following the last application identifier '30', the data representing the delivery quantity is given to show 3 pieces.There are about 100 application identifiers except the above. The required data is selected and included in the barcodes by users.GS1-128 is not intended to represent fixed data, but the data is selectable by the user. Therefore, for consistent use of GS1-128 among companies, the standards for the barcode system with the data available shall be prepared by the respective industry and the groups of companies involved. ・With GS1-128 being added to EAN code and the standard distribution code (ITF), it can be used as the code to add more data.GS1-128 is designed to represent the application identifiers and the products relative data or the transaction data of the companies using CODE 128.In other words, GS1-128 is the standard for the applications to represent the various data.
CODE 128 is the standard just for the barcode itself. The difference between GS1-128 and CODE 128 is whether it represents the application or not.Since GS1-128 uses the barcode composition of CODE 128, any that can read CODE 128 can be used to read the GS1-128 data.Application Identifier Application IdentifierThere are 100 types of application identifiers that can be classified as follows. Some of the data following each application identifier has a fixed number of digits (standard carton ID, date and unit of measurement), while the others have an undefined number of digits (lot number, serial number, quantity in package, quantity and order number).
Package indicator0Corrugated cardboard boxes that contain the mixed products18Corrugated cardboard box for one-item that contains the same quantity. Setting within the range of 1 to 8.
In many cases, 1 is set.9The corrugated cardboard box that contains the different quantity for one-itemSince 'delivery container code' has the same data composition as for the EAN code and the standard distribution code, it can be used only on the condition that EAN and standard distribution codes are not printed on corrugated cardboard boxes.' Delivery container code' is called SCC-14 (Shipping Container Code) in Europe and America.
