What TF Srivichai is

TF Srivichai is a looped Thai sans in four styles — Regular, Italic, Bold and Bold Italic — released free in 2008 (B.E. 2551) by the Federation of Thai Printing Industries (FTPI) under the SIL Open Font License 1.1, so it is free for commercial use. Searches for “TF Srivichai” and “tf srivichai” both mean this font.

According to its ThaiFaces specimen, TF Srivichai is an improved version of the font EACSriwichai and is one of 13 fonts from the Federation’s type development project. Every font in the project carries the TF prefix, including TF Phethai, the heavy face from the same programme.

The font files credit the designer only as “FTPI”. They name neither the person who did the digitisation nor the designer of the original EACSriwichai, so we credit the Federation as copyright holder and publisher, as the files do.

Origin: the Federation’s type development project

TF Srivichai came out of a copyright problem in the Thai printing trade: the Federation received complaints from its members, so it took older typefaces nobody was developing any more, rebuilt them as Unicode OpenType fonts, and gave them away. ThaiFaces quotes this background from the Federation’s 2010 press release on the project.

The brief was practical. Printers, colour-separation houses and design firms wanted fonts they could use without arguing over who was liable for a typeface’s copyright, and the trade wanted the older faces it still relied on to work with modern computers. The description field inside the font files lists the sponsors: The Federation of Thai Printing Industry Foundation, Thailand Printing Exhibition Fund Foundation, The Thai Printing Association, The Publishers and Booksellers Association of Thailand, and three companies — Continental Packaging (Thailand), President Supply and E.Hing Printing Press.

Letterforms

TF Srivichai is a looped sans with smooth, near-monoline strokes and a fairly light Regular, paired with a plain grotesque Latin that stays out of the Thai’s way. It is built to work quietly in running text.

The gap between Regular and Bold is wide enough to build real hierarchy: in our test, setting the same 29 Thai consonants at the same size, the Bold put down about 1.7 times the ink of the Regular. The italics slant at 12 degrees according to the files’ own metadata, and each file holds 743 glyphs covering Thai plus full upper- and lowercase Latin.

Against TH Sarabun New, another four-style looped face, TF Srivichai gives a different texture on the same skeleton without giving up legibility. Set your own text in both in the Thai font tester.

Download TF Srivichai

The entry point we recommend is the TF Srivichai specimen on ThaiFaces, which carries both the download button and the licence. The button points to TF_Srivichai.zip, about 224 KB, on freefont.thaifont.info. The zip holds four .ttf files, one per style.

Use the link ThaiFaces points to rather than a general font aggregator, so the files match the specimen, and keep the licence file with your project.

Best use cases

TF Srivichai suits running text and documents that need a full bold-and-italic set in a looped face that is unambiguously cleared for commercial use. Strong briefs:

• Print, brochures, manuals and reports with long text
• Corporate documents that use bold for headings and italic for emphasis
• Work that embeds fonts in PDFs or ships files to a printer
• Websites that want a self-hosted looped face under an open licence

Where it does not fit: branding and headlines that need a strong personality. Set those in a loopless face such as Kanit and let TF Srivichai carry the text. Compare other faces in looped Thai fonts.

Licensing

TF Srivichai is free for commercial use. The licence file ThaiFaces links states “This Font Software is licensed under the SIL Open Font License, Version 1.1”, and ThaiFaces records the terms as free to use under OFL 1.1. No permission or payment is needed to use it in design work.

Ahead of the OFL text, the document carries FTPI’s own agreement, which is also embedded in the licence field of every font file. Its four points:

• Use, reproduce, study, adapt and distribute at no charge, but do not sell the font by itself unless bundled with a computer program
• Notify the Federation in writing if you adapt the font
• Adapted versions may not use the reserved names, which include all four TF Srivichai styles
• Adapted versions must be released under the same terms

In practice: use it in client work, print and on the web straight away. If you redraw glyphs or add characters, rename the font and notify the Federation first. That places TF Srivichai among the genuinely commercial-safe free Thai fonts. For how OFL differs from other licences, see the Thai font licensing guide.
