316 GS1 DataBar Limited5. Bar Code Height1. Left Guard Pattern2. Right Guard Pattern3. Data Character4. Check Character3. Data Character(18,7) (26,7)(26,7)Name Description1 Left Guard Pattern Provides the bar code area of the left side. It consists of bars and spaces of one module(minimum unit consisting of bars and spaces).2 Right Guard Pattern Provides the bar code area of the right side. ISO/IEC 24724 standard specifies it asfollows. (The number in parentheses indicates the number of modules.)ISO/IEC 24724 2011: combination of (1) space, (1) bar, and (5) spaceISO/IEC 24724 2006: combination of (1) space and (1) barReference• For better bar code reading quality, in this laser marker, the rightmost space of the right guard pattern consists of sixmodules, adding one extra module to that of the standard when it is set to ISO/IEC 24724 2011.3 Data Character Has the (n, k) structure. “n” indicates the number of modules and “k” indicates that ofbars and spaces that make up the character. This data character is composed with 7bars and spaces consisting with 26 modules. The element is arranged from left to rightas shown in the figure above.4 Check Character This check character is composed with 7 bars and spaces consisting with 18 modules,and it is set between 2 data characters. It is used to check if the read data is corrector not by putting the value calculated with the certain formula on just before the stopcharacter for re-calculation.5 Bar Code Height The minimum value of bar code height is 10 times as high as the module width.Content of code data• GS1 DataBar Limited indicates the numerical (0 to 9).• The data consists of application identifier “01” and 13-figure numerical characters.• The application identifier indicates the content of data and automatically added.• The data that can be bar-coded is “0000000000000” to “1999999999999”. The data “2000000000000” or more cannotbe bar-coded.ME-LP400V-OP-6
