EAN-14条码 基于EAN-128的编码规则,应用标识符为01 后接14位长度的数据,其体现形式有2种,只显示14位的数据和显示(01)+14位的数据,无论怎么做,标准的EAN-14条码扫描出来的数据是16位的长度。
Label mx 条码软件里包含有EAN-14条码类型,可以方便制作出含01的16位EAN-14的条码:
ITF-14条码 属于交叉二五条码(Interleaved 2 of 5)的规范约定,编码长度固定的14位数字数据,常用于箱码标签的印刷使用。
Label mx 条码软件里包含有ITF-14条码类型,用Interleaved 2 of 5 类型也可以做出来:
DUN-14 条码 严格说DUN-14(Distribution Unit Number)不是一个真正意义上的条码类型,它是为使用在集装箱上的一种编码规范,通常是由12、13位数字+1位校验码组成。采用的类型为ITF-14或EAN-128,常用EAN-128类型。
DUN is not really a barcode type. It’s a Distribution Unit Number. However, it is frequently constructed from 12/13 digit retail barcode numbers, and uses a special check digit.
DUN-14 numbers may be represented by ITF or EAN 128 barcode, and modern implementation should use EAN128.
DUN-14 in EAN128 barcode form may be created by providing 13 digits (the Logisitcal Variant digit – normally 0 in the UK) followed by the first 12 of the retail digits (eg. from EAN-13 numbers but without EAN's check digit). The DUN check digit is then calculated and the barcode symbol produced using EAN128 symbology.
