Noto Serif CJK is here!

Posted by Xiangye Xiao and Jungshik Shin, Internationalization Engineering team

Today, in collaboration with Adobe, we are responding to the call for Serif! We are pleased to announce Noto Serif CJK, the long-awaited companion to Noto Sans CJK released in 2014. Like Noto Sans CJK, Noto Serif CJK supports Simplified Chinese, Traditional Chinese, Japanese, and Korean, all in one font.

A serif-style CJK font goes by many names: Song (宋体) in Mainland China, Ming (明體) in Hong Kong, Macao and Taiwan, Minchō (明朝) in Japan, and Myeongjo (명조) or Batang (바탕) in Korea. The names and writing styles originated during the Song and Ming dynasties in China, when China's wood-block printing technique became popular. Characters were carved along the grain of the wood block. Horizontal strokes were easy to carve and vertical strokes were difficult; this resulted in thinner horizontal strokes and wider vertical ones. In addition, subtle triangular ornaments were added to the end of horizontal strokes to simulate Chinese Kai (楷体) calligraphy. This style continues today and has become a popular typeface style.

Serif fonts, which are considered more traditional with calligraphic aesthetics, are often used for long paragraphs of text such as body text of web pages or ebooks. Sans-serif fonts are often used for user interfaces of websites/apps and headings because of their simplicity and modern feeling.

Design of '永' ('eternity') in Noto Serif and Sans CJK. This ideograph is famous for having the most important elements of calligraphic strokes. It is often used to evaluate calligraphy or typeface design.

The Noto Serif CJK package offers the same features as Noto Sans CJK:

  • It has comprehensive character coverage for the four languages. This includes the full coverage of CJK Ideographs with variation support for four regions, Kangxi radicals, Japanese Kana, Korean Hangul and other CJK symbols and letters in the Unicode Basic Multilingual Plane of Unicode. It also provides a limited coverage of CJK Ideographs in Plane 2 of Unicode, as necessary to support standards from China and Japan.

Simplified Chinese
Supports GB 18030 and China’s latest standard Table of General Chinese Characters (通用规范汉字表) published in 2013.
Traditional Chinese
Supports BIG5, and Traditional Chinese glyphs are compliant to glyph standard of Taiwan Ministry of Education (教育部國字標準字體).
Supports all of the kanji in  JIS X 0208, JIS X 0213, and JIS X 0212 to include all kanji in Adobe-Japan1-6.
The best font for typesetting classic Korean documents in Hangul and Hanja such as Humninjeongeum manuscript, a UNESCO World Heritage.
Supports over 1.5 million archaic Hangul syllables and 11,172 modern syllables as well as all CJK ideographs in KS X 1001 and KS X 1002
Noto Serif CJK’s support of character and glyph set standards for the four languages
  • It respects diversity of regional writing conventions for the same character. The example below shows the four glyphs of '述' (describe) in four languages that have subtle differences.
From left to right are glyphs of '述' in S. Chinese, T. Chinese, Japanese and Korean. This character means "describe".
  • It is offered in seven weights: ExtraLight, Light, Regular, Medium, SemiBold, Bold, and Black. Noto Serif CJK supports 43,027 encoded characters and includes 65,535 glyphs (the maximum number of glyphs that can be included in a single font). The seven weights, when put together, have almost a half-million glyphs. The weights are compatible with Google's Material Design standard fonts, Roboto, Noto Sans and Noto Serif(Latin-Greek-Cyrillic fonts in the Noto family).

    • It supports vertical text layout and is compliant with the Unicode vertical text layout standard. The shape, orientation, and position of particular characters (e.g., brackets and hiragkana letters) are changed when the writing direction of the text is vertical.

    The sheer size of this project also required regional expertise! Glyph design would not have been possible without leading East Asian type foundries Changzhou SinoType Technology, Iwata Corporation, and Sandoll Communications.

    Noto Serif CJK is open source under the SIL Open Font License, Version 1.1. We invite individual users to install and use these fonts in their favorite authoring apps; developers to bundle these fonts with your apps, and OEMs to embed them into their devices. The fonts are free for everyone to use!

    Adobe Typekit improves the Rosario typeface family

    Since 2010, Google Fonts been collaborating with the Adobe Typekit team to create better web font technology. And now that many fonts first published by Google Fonts are also available in Adobe Edge Web Fonts, we’re extending that collaboration beyond just software to fonts themselves.

    Together with Adobe, we want to improve the quality of open source fonts available to everyone publishing on the web. As a first step, the Typekit team has optimized Rosario, a humanist sans serif based on the classic proportions of Garamond’s type.

    To start the process, Typekit reached out to the foundry, Omnibus Type, to request up to date copies of the font source files. Here are some examples of the possible optimizations that the Adobe team might make to a web font:

    • Convert and/or clean up outlines, for design fidelity and file size efficiency
    • Re-componentize source fonts, for file size efficiency
    • Remove/reassign glyphs with incorrect Unicode code points, for semantic value
    • Add common missing glyphs (non-breaking space, soft hyphen)
    • Set vertical metrics values according to best practices
    • Set underline and strike-through values, for design consistency
    • Contribute PostScript hints and (if a typeface was designed for small sizes like paragraph text) TrueType instructions (also called hinting), which consist of instructions to the rasterizer embedded in the font file itself

    After making some of these improvements, Typekit sent their version back to the foundry to review and release on the Omnibus Type homepage. The updated Rosario family is now available in Typekit, Adobe Edge Web Fonts and Google Fonts.

    Together with the Typekit team, we’re looking forward to more quality improvements in the future!

    More places to get great fonts

    Open source fonts are good for the web: they’ve helped spur web font adoption, and made it easier for anyone to contribute improvements to fonts for the whole web community.

    Today, we’re happy to announce that all the fonts in the Google Web Fonts directory are also available via Adobe’s new Edge Web Fonts service.

    And on the heels of the recent release of Source Sans Pro, another Adobe designed open source font, Source Code Pro, is available today from both Google Web Fonts and Edge Web Fonts.

    We’re also working with the Adobe team to hint some of the fonts in the collection, a process that will make them look better at smaller text sizes.

    Here’s to a more accessible, translatable, and beautiful web!
