![]() ![]() Some applications such as Adobe InDesing automatically embed all fonts when pages are exported to PDF.Īcrobat Distiller offers an option to automatically add missing fonts to PostScript files it has to process. A custom encoding can be used by defining a ‘Differences Array’. The following types of encoding are supported by the PDF file format: Each font in a PDF uses a specific type of encoding, either a standard one or a custom one. ![]() This refers to the mapping of a character code to a particular glyph (character shape) description. The Multiple Master fonts that are used for this are:Īnother important aspect of font handling is the encoding. This way, the document will not be represented exactly as the designer wanted it to, but at least the text won’t reflow. If certain fonts are missing from the PDF file, Adobe Acrobat and Adobe Reader will automatically try to emulate the missing font by using one of the Multiple Master fonts that are built into these programs. For subsetted fonts, the font name is preceded by 6 random characters and a plus sign. This means that PDF files with subsetted fonts are smaller than PDF files with embedded fonts. If the “$” character doesn’t appear anywhere in the text, that character is not included in the font. Subsetting: Only those characters that are actually used in the lay-out are stored in the PDF. Embedding: A full copy of the entire character set of a font is stored in the PDF. There are two mechanisms to include fonts in a PDF: ![]() This makes sure that the file can be viewed and printed as it was created by the designer. What is the difference between Embedded fonts and Subset Embedded fonts?īy preference any fonts that are used in a layout are also included in the PDF file itself. The ability to embed OpenType directly was added for the forms capabilities of PDF, it offers no immediate advantage for prepress users. In prior releases OpenType fonts are embedded as either Type 1 or TrueType fonts. ![]() OpenType: From PDF 1.6 onwards, OpenType fonts can be stored directly in PDF files. Composite fonts (Type 0): both Type 1 (CIDFontType0) and TrueType (CIDFontType2) are supported. The PDF file format supports the use of the following font formats: With new open source typefaces appearing all the time, the open source option will continue to be a decent solution for many design and web projects.What fonts are supported in the PDF format? The quality and flexibility of those fonts comes at a premium, but if the typeface fills the need, it is usually worth the cost.įor projects that don’t require the flexibility of full-featured commercial fonts, or if you simply don’t want to deal with licensing complexities, open source fonts offer a hassle-free alternative. For projects that require a well-designed typeface with many styles, commercially licensed fonts might be the only way to go. So are open source fonts good alternatives to commercial ones? It depends. But many projects require full typeface families that span the full spectrum from light to regular to semi-bold-semi-extended-italic font styles.įor all these reasons, the more versatility you require in your typefaces, the harder it will be to find a good one in the open source world. So for projects that call for a single-face display font, you might find a few decent open source alternatives. Unfortunately, many open source fonts have only one style, or if you are lucky, a regular and an italic version. These issues can cause incorrect page and document rendering, performance problems and even system crashes. It’s very difficult to wade through all of them to find quality, full-featured fonts.Įven fonts from reputable sources such as Google have problems that include incomplete glyph sets, poor kerning and improper file structures. Open source fonts now number in the thousands and they vary widely in integrity. What Are the Downsides of Open Source Fonts? Google even provides the code required to embed your chosen fonts in webpages. In fact, Google offers a free web font service that features hundreds of open source fonts that you can download to your desktop. There is no such financial requirement with open source fonts, making them perfect candidates for website use. If you utilize a traditional, commercial font on a website, you must either purchase or rent the web version of the font to legally host or use it on your web server. Many open source fonts use the Open Font License, which was created to make project collaboration easier for academic and linguistic communities. Open source fonts are licensed so that anyone can use them anywhere for any purpose, free of charge. Fonts are software and just like desktop or enterprise applications, they have usage licenses that you must follow to legally use them. ![]()
