Digital devices are gradually replacing paper, and reading on screens with various resolutions has led sans serif typefaces to replace serif typefaces. The high readability of serif typefaces is something we can’t ignore. In Chinese, MingTi /SongTi is just like serif in Latin, with greater contrast on the strokes. For serif typefaces, there are some with higher x-height for using on texts, and also with additional contrast for headlines. The contrast of horizontal and vertical strokes of MingTi and SongTi was launched by Chinese font foundries in a similar manner. In order to use typefaces for different occasions, we launched a SongTi with three axes; including weight, contrast, and optical size. We are hopeful that the typeface can fit different needs accordingly. This type family is designed in the contemporary structure of SongTi, integrating features of KaiTi and three axes. With these comprehensive characteristics, the type family can be used in texts, headlines, and screens of various resolutions to achieve the best user experience.
