确定代码128条码的最大可用宽度

Question

我正在寻找某种可用的公式，以确定我可以在代码128条形码上容纳多少数据，这个条形码不大于给定的宽度。用例是一个腕带，上面印有条形码。

最小的条形是否需要最小的尺寸才能使一切可见？是否在任何地方都有尺寸比(即"Z占用的空间是0的x倍“)？我看到代码128支持对数字进行字符串压缩。更多的数据是通过删除alpha字符而被删除的，但是这样做我最终会得到更多相同宽度的数据吗？

编辑:对数字字符串进行压缩，解决方案是只测试10、12、15等字符串。我们决定使用12，因为这是远远超过我们的使用和扫描非常容易在一个1英寸的腕带，留下10%的每边开放。我仍然对所要求的信息感兴趣，不过如果有人有洞察力的话。

Answer 1

所有字符的相对宽度相等。代码128 C允许将两个数字放入单个字符中，但如果需要混合和匹配数字和字母，则需要连续使用两对或多对数字，以使切换字符的额外负担成为值得的。

在一定高度之后，垂直尺寸并不重要，这取决于扫描仪。

字符的宽度与其可读性成正比，取决于生成软件、硬件和打印媒体。

我测量密度的字符每英寸和一个喷墨打印机，我可以得到约155个字符每可扫描英寸。我想我需要一台更好的打印机，或者更好的扫描仪。

下面是一个在15.6CPI下用Code128B编码的40个字符串(43个字符包括开始、检查和停止)。

@Alex DeCamillo，

编码128符号的ISO/IEC 15417规范定义了一个计算宽度的公式，该公式利用字符数、最窄元素的宽度和所需的静音区来计算整体宽度。您还可以将其与常量宽度一起使用，以计算最小元素的所需宽度，等等。不幸的是，我无法在规范之外找到这个公式，所以我不能在不违反规范条款的情况下共享该公式，但是您可以在这里获得规范：https://www.iso.org/standard/43896.html。
