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. Only a few type foundries actually release fonts with such severe restrictions, but they do exist. Applications that properly honor the licensing policy of such a font will not embed it in a PDF. In TrueType and OpenType fonts, they can add this restriction in the font data. Keep in mind that font foundries can forbid font embedding for certain typefaces through their end-user license agreement. 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 layout 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. Composite fonts (Type 0): both Type 1 (CIDFontType0) and TrueType (CIDFontType2) are supported.īy preference, any fonts that are used in a layout are also included in the PDF file itself.Some tools still do this today because it leads to a smaller PDF file if none of the extra features in OpenType are required. This was common practice with applications like Acrobat or InDesign before PDF 1.6 was released. That means PDF production tools can embed an OpenType font by taking it apart, copying either the TrueType or the CFF (Type 1) glyphs and embedding those in the PDF in their original/old style format. Within an OpenType font, the character shapes or glyphs can be encoded using either TrueType or Type 1. OpenType: From PDF 1.6 onwards, OpenType fonts can be stored directly in a PDF file. The PDF file format supports the use of the following font formats: Some general recommendations about font handling can be found at the bottom of this page. How and why to outline fonts is discussed. It covers the basics about the supported font types, encodings, and the ways of enclosing fonts in a PDF, by either embedding or subsetting them.

But, nothing beats the “real” conference, and this is how it was this year. Which was awesome, considering the circumstances. Over the last two years, we were able to attend it online, as it was happening in the virtual world. It happens in Las Vegas, Nevada, at The Mirage Hotel.
