Source Serif Pro

Source Serif Pro is a set of OpenType fonts to complement the Source Sans Pro family. In addition to functional OpenType fonts, this open source repository provides all of the source files that were used to build them using the Adobe Font Development Kit for OpenType (AFDKO).

Building the fonts from source


To build the binary font files from source, you need to have the Adobe Font Development Kit for OpenType (AFDKO) installed. The AFDKO tools are widely used for font development today, and are part of most font editor applications.

Building one font

The key to building OTF or TTF fonts is makeotf, which is part of the AFDKO toolset. Information and usage instructions can be found by executing makeotf -h.

In this repository, all necessary files are in place for building the OTF and TTF fonts. For example, build a binary OTF font for the Regular style like this:

$ cd Roman/Regular/
$ makeotf -r

Building all fonts

For convenience, a shell script named is provided in the root directory. It builds all OTFs and TTFs, and can be executed by typing:

$ ./
