# 在Latex编译出的文件中嵌入所有字体

IEEE 提交论文时，需要在`PDF eXpress`网站进行格式检查和转换，貌似经常遇到的问题是`xxx字体没有嵌入`。

对于`win/word`用户，修正pdf虚拟打印选项即可解决。然而对于`latex`用户，可能需要花一些功夫。

下面说一个最简单的解决方案，所有工具都是`texlive`自带的，直接用即可：

1. 转换到ps：
`pdftops 你的文件.pdf`
2. 用合适的设置转换回pdf：
`ps2pdf14 -dPDFSETTINGS=/prepress 你的文件.ps`
3. 检查：
`pdffonts 转换后的文件.pdf`

示例输出：

所有字体名字的`emb`和`sub`都是`yes`。

下面是另一个，永久性更改系统设置，不用每次转换，觉得不太合适。方在这里供参考：

Getting pdflatex to embed all fonts

My friend Yuhong reminded me to make sure I embed all fonts in the pdf file for our ICDM-05 paper. This seems to be an IEEE requirement.
Turns out to be a non trivial task, but not difficult. Here’s what I did (applies to a Linux TeTeX 3.0 distribution):
As root, type “updmap –edit”, edit the config file so that it has the following content:

```
#pdftexDownloadBase14 false
pdftexDownloadBase14 true
```

Run pdflatex over your document.

Run pdffonts over the produced pdf file, all fonts should have true in the columns “emb” and “sub”.
