18、nt (EN 12323:2005) has been prepared by Technical Committee CEN/TC 225 “AIDC Technologies“, the secretariat of which is held by NEN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2005,
19、and conflicting national standards shall be withdrawn at the latest by November 2005. This document supersedes EN 12323:1998. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Bel

EN 12323:2005 (E) 4IntroductionThe techn
21、ology of bar coding is based on the recognition of patterns encoded in bars and spaces of defined dimensions. There are a number of methods of encoding information in bar code form, known as symbologies, and the rules defining the translation of characters into bar and space patterns and other essen
22、tial features are known as the symbology specifications. “Code 16K“ is one such symbology. Previously, symbology specifications have been developed and published by a number of different private organisations, resulting in certain instances in conflicting requirements for certain symbologies. Manufa
23、cturers of bar code equipment and users of bar code technology require publicly available standard symbology specifications to which they can refer when developing equipment and application standards. EN 12323:2005 (E)51 Scope This document: specifies the requirements for the multi row bar code symb
24、ology known as “Code 16K“; specifies “Code 16K“ symbology characteristics, data character encodation, dimensions, tolerances, decoding algorithms and user-defined application parameters; describes a subset of “Code 16K“ assigned to EAN International. 2 Normative references The following referenced d

34、a overhead: per row: 15 modules; per symbol: 33 modules minimum, 81 modules maximum. EN 12323:2005 (E)74.2 Symbol structure Each “Code 16K“ symbol consists of 2 to 16 rows. Each row shall comprise: a) leading quiet zone; b) start character; c) 1X guard bar (where X is the nominal width of a narrow b
35、ar or space); d) 5 symbol characters; e) 1 stop character; f) trailing quiet zone. Figure 1 illustrates the row structure. Rows shall be separated from each other by a horizontal separator bar. The top and bottom of the symbol shall also have separator bars which shall extend to the ends of the quie
36、t zones. Figure 1 “Code 16K” row structure Figure 2 shows the structure of a full 16-row symbol. The symbol characters are ordered from the leftmost character of the first (top) row, through each row left to right to the rightmost character in the last (bottom) row. The first symbol character is the
37、 “mode” character S. The last two characters are the check characters C1 and C2. The remaining symbol characters encode the data for the symbol. Figure 2 “Code 16K” symbol structure EN 12323:2005 (E) 8Figure 3 illustrates a complete symbol encoding the data “ab0123456789” in “Code 16K”. Figure 3 “Co
38、de 16k” symbol encoding “ab0123456789” 4.3 Character assignments 4.3.1 Symbol character encodation There are 107 “Code 16K“ symbol characters. Each symbol character consists of eleven 1X-wide modules. Each symbol character consists of three space elements alternating with three bar elements, startin
39、g with a space. Each bar or space element may consist of 1 to 4 modules. Table 1 defines all the “Code 16K“ character assignments. In the column headed Symbol Character Structure the numeric value represent the widths of the elements in modules or multiples of the X dimension. Symbol character parit
40、y is defined by the sum of the bar modules in any symbol character. In “Code 16K“ this sum shall always be odd (odd parity). This odd parity feature enables character self-checking to be carried out. Figure 4 illustrates the symbol character value 33. Figure 4 Symbol character value 33 4.3.2 Data ch
41、aracter encodation “Code 16K“ has three unique data character sets, shown in Table 1 as code sets A, B and C. The symbol character bar and space patterns shown are equivalent to the data characters listed in the columns for code A, B or C. The choice of data character set depends on the mode charact
42、er (starting symbol character), or the use of code set A, code set B or code set C characters or the shift characters. The code set can be redefined within the symbol by the use of code set or shift characters. The same data may be represented by different “Code 16K“ symbol characters, through the u
43、se of different combinations of mode, code set or shift characters. Annex F contains guidelines to generate the smallest symbol for given data. An application need not specify the code set to be used. Each symbol character is assigned a numeric value listed in Table 1. This value is used in calculat
44、ing the check characters C1 and C2. It may also be used to provide a conversion to and from ASCII decimal values when encoding in code sets A and B (see Annex G). EN 12323:2005 (E)94.3.3 Code sets 4.3.3.1 Code set A Code set A includes all of the standard upper case alphanumeric characters together
45、with the control characters (i.e. characters with ASCII values from 00 to 95 inclusive), and eleven special characters. 4.3.3.2 Code set B Code set B includes all of the standard upper case alphanumeric characters together with the lower case alphabetic characters (i.e. characters with ASCII values
46、from 32 to 127 inclusive), and eleven special characters. 4.3.3.3 Code set C Code set C includes the set of 100 digit pairs from 00 to 99 inclusive, as well as seven special characters. This allows numeric data to be encoded, two data digits per symbol character, at effectively twice the density of
47、standard data. EN 12323:2005 (E) 10Table 1 “Code 16K“ character encodations NOTE 1 Shift is denoted as 1S, Double Shift is denoted as 2S, Triple Shift is denoted as 3S.
