Data CharacterName Description1 Left/Right GuardPatternProvides the bar code area. It consists of bars and spaces of one module (minimum unitconsisting on bars and spaces).2 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. As shown in the figure above, the datacharacter is arranged so as to facing to the adjacent finder pattern (toward the arrowdirection).3 Finder Pattern Functions as a check character or segment identifier, too, which makes symbols to beeasily recognized. It consists of five elements having 15 modules.4 Bar Code Height In the standard case, the minimum value of bar code height is 33 times as high as themodule width. For Truncated, Stacked, and Stacked Omnidirectional, it is 13, 13 and 69times respectively.GS1 DataBar symbols has the three type of version as shown below, in addition standard.GS1 DataBar TruncatedGS1 DataBar Truncated lowers the bar code height of GS1 DataBar to meet the elongated marking field. The minimumvalue of bar code height is 13 times as high as the module width.GS1 DataBar StackedGS1 DataBar Stacked is the two-tiered symbol consisting of halves of GS1 DataBar Truncated divided into two to meet theproducts with extremely narrow marking field. The upper tier consists of left half of GS1 DataBar Truncated. A guard patternis added at its right end. The bottom tier consists of right half of GS1 DataBar Truncated. A guard pattern is added at its leftend. The separator of one module height is inserted between tiers. The minimum value of bar code height is 13 times ashigh as the module width.ME-LPMSZ-OP-7
