With OTF, they could reside in the same file as the default typeface and remain easily accessible to designers and the like. For designers, both amateur and professional, the main useful difference between OTF and TTF is in the advanced typesetting features. In addition, OTF features embellishments like ligatures and alternate characters—also known as glyphs—that exist to give designers more options to work with. In other words, OTF is indeed the "better" of the two due to the additional features and options, but for the average computer user, those differences don't really matter.
You can't, for example, just decide to use a different version of an "F" in Facebook or embellish common connecting letters like "TH" to make them look like ornate typography. Those that use these will typically do so in Adobe Creative Suite and for the sole purpose of making subtle tweaks that make text look better for print or on the web.
Let's flesh things out by looking at three of the most common additions to OTF packages. Glyphs are alternate characters that you can change to when you're looking for something stylistically different from the default.
Traditional characters might look something like this:. For example, if you need a different "A," you could elect to use a glyph that displays an "A" with different stylistic qualities or one that is used as the default in other alphabets and languages. For example:. Ligatures are strictly a stylistic addition. These are most common with script fonts, but they appear in nearly all high-end packages.
Cheaper fonts, or those you can find for free online, are less likely to have many glyphs, ligatures, or other extras. Ligatures are typically combinations of two different letters that meld together to become a stylistic two-in-one entity. When letters are combined like this, they typically end up with embellished designs or adjusted spacing between the two.
Alternate characters are just what they sound like: alternatives to non-alphanumeric characters. The format was based on the TTF format and intended to succeed it. Open Type Fonts OTFs can contain approximately 65, glyphs, supports the Unicode character encoding, and is supported cross-platform. The CFF format is far more popular. TTF fonts also allows type designers a high-level of control over how the rasterizer converts the mathematically-defined glyph paths into pixels.
This allows for crisp fonts at small point sizes when displayed on low resolution displays. However these days smarter rasterizers and higher-density displays have minimized the benefit of manual hinting. Most platforms today ignore much of the hinting information provided.

Headlines are often centered. It is generally not good to mix centered text with flush left or flush right text. Also see character encoding, glyph, keyboard layout. This gives a feeling of variety without losing harmony. Within a particular font, contrast also refers to the variety of stroke thicknesses that make up the characters. Helvetica has low contrast and Bodoni has high contrast. In some typefaces, the uppercase J and Q also descend below the baseline. Typically such a font is not as readable at smaller sizes for large amounts of text.
If a serif font with optical sizes, it will likely have lighter weight main stems and much lighter weight serifs and crossbars than a text-size version of the same typeface. Refers to the resolution at which a device, such as a monitor or printer, can display text and graphics. Monitors are usually dpi or less, and laser printers are dpi or higher. An image printed on a laser printer looks sharper than the same image on a monitor.
This method is used to indicate the start of a new section of text, such as a chapter. It indicates that a word or phrase has been omitted. Em is traditionally defined as the width of the uppercase M in the current face and point size. It is more properly defined as simply the current point size. For example, in point type, em is a distance of 12 points. En is traditionally defined as the width of the uppercase N in the current face and the current point size.
It is more properly defined as half the width of an em. For example, the italic style of the Garamond family is a face. A collection of faces that were designed and intended to be used together.
For example, the Garamond family consists of roman and italic styles, as well as regular, semi-bold, and bold weights. Each of the style and weight combinations is called a face.
If the same text is not aligned on the right margin, it is said to be set flush left, ragged right. The term ragged right is sometimes used alone to mean the same thing. If the same text is not aligned on the left margin, it is said to be set flush right, ragged left. The term ragged left is sometimes used alone to mean the same thing. Before scalable type, there was little distinction between the terms font, face, and family.
Font and face still tend to be used interchangeably, although the term face is usually more correct. The collection of faces that were designed together and intended to be used together. For example, the Garamond font family consists of roman and italic styles, as well as regular, semi-bold, and bold weights.
In the context of modern computer operating systems, it is often defined as a shape in a font that is used to represent a character code on screen or paper. The most common example of a glyph is a letter, but the symbols and shapes in a font like ITC Zapf Dingbats are also glyphs. Also see character, character encoding, keyboard layout. This is sometimes referred to as outdenting. This is an effective style for displaying lists of information.
Also the category of faces that are designed to work best in headline text. The upright faces are often referred to as roman. Justified text has a more formal appearance, but may be harder to read. Also see character, character encoding, glyph. The term originally referred to the thin lead spacers that printers used to physically increase space between lines of metal type.
Most applications automatically apply standard leading based on the point size of the font. Closer leading fits more text on the page, but decreases legibility. Looser leading spreads text out to fill a page and makes the document easier to read. Leading can also be negative, in which case the lines of text are so close that they overlap or touch. Kerning allows adjustments between individual letters; letterspacing is applied to a block of text as a whole.
Letterspacing is sometimes referred to as tracking or track kerning. In some typefaces, character combinations such as fi and fl overlap, resulting in an unsightly shape.
The fi and fl ligatures were designed to improve the appearance of these characters. Margins typically need to be created on the edges of a page, since most printers can't print to the very edge. White space also makes a document look better and easier to read.
Oblique is similar to italic, but without the script quality of a true italic. The upright faces are usually referred to as roman. As jointly defined by Microsoft and Adobe Systems, it is technically an extension of Microsoft's TrueType Open format, which can contain either PostScript font outlines or TrueType font outlines in a single font file that can be used on both Macintosh and Windows platforms.
It can also include an expanded character set based on the Unicode encoding standard plus advanced typographic intelligence for glyph positioning and glyph substitution that allow for the inclusion of numerous alternate glyphs in one font file. Rules are commonly used to separate columns and isolate graphics on a page. A pica is equal to 12 points. The traditional British and American pica is 0. There are approximately 72 points to the inch.
A pica is 12 points. The distance from the top of the highest ascender to the bottom of the lowest descender in points. In Europe, type is often measured by the cap-height in millimeters.
Compare to a drop cap. This technique greatly reduces legibility, especially with small type. Rules and other graphic devices should be used sparingly, and only for clarifying the function of other elements on the page.
Generally a low-contrast design. Sans serif faces lend a clean, simple appearance to documents. Serifs improve readability by leading the eye along the line of type.
Generally used only with larger display sizes. This makes it easier to set tabular matter. Sometimes also referred to as letterspacing. Type 1 The original international type standard for scalable type, invented by Adobe Systems. Type 1 is one of the most commonly available digital type formats and is often used by professional digital graphic designers. It is being superceded by OpenType. A typeface is often part of a type family of coordinated designs.
The individual typefaces are named after the family and are also specified with a designation, such as italic, bold or condensed. For example, the Garamond font family consists of roman and italic styles, as well as regular, semibold, and bold weights. Color is a function of the relative thickness of the strokes that make up the characters in a font, as well as the width, point size, and leading used for setting the text block.
Weight is indicated by relative terms such as thin, light, bold, extra-bold, and black. White space should be considered an important graphic element in page design. What you see on the screen is what you will get on printed output, as accurately as the screen can render it. It is also the height of the body of lowercase letters in a font, excluding the ascenders and descenders. Some lower-case letters that do not have ascenders or descenders still extend a little bit above or below the x-height as part of their design.
The x-height can vary greatly from typeface to typeface at the same point size. OpenType Fonts. What are the advantages of OpenType? OpenType is known for:. A single, cross-platform font file that can be used on both Macintosh and Windows platforms.
A nearly unlimited character set based on the international Unicode encoding standard for rich linguistic support. Advanced typographic capabilities related to glyph positioning and glyph substitution that allow for the inclusion of numerous alternate glyphs — such as old-style figures, small capitals, and swashes — in one font file.
A compact font outline data structure for smaller font file sizes. What compression technologies are incorporated in OpenType?

This means that Iotadieresistonos, Iotadieresisacute, Iotadieresistilde, and Iotadieresisgrave lose every mark but the dieresis; the same is true for Upsilon. Do OpenType Fonts have any any application compatibility or historical issues? Typically, a base font and its style-linked bold are handled correctly, while additional weights which should appear separately in the CorelDraw font menu do not appear at all.
For example, if the regular and the bold are style-linked, the semibold fonts might not appear in CorelDraw's font menu. These appear to be the same cases listed for CorelDraw above. Depending on the printer and driver, this may or may not affect printed output.
These may be the same cases listed for CorelDraw above. Note that the font still works correctly. FrameMaker for Windows will also show an error message when opening a Macintosh FrameMaker document using such a font, but the font will display and print correctly. This occurs only with the Windows version. Excel 97, Word 97, Word , Office and Office do not have this problem.
If you define a style using an OpenType font, the font defined in the style may revert to Times when you save the style. This is fixed in the PageMaker 7. QuarkXPress 6. Generally, the font still outputs correctly. This does not affect printed output. In windows, why do some fonts not appear in application font menus style linking? Workaround: The other "missing" fonts are accessible by using the bold and italic style buttons in each application. Use the Adobe Web site.
Click on the specific font in the package to get to the Web page that shows the full character set for that font. Click the "More Info" tab. This shows both how the font is listed in the menu of Windows applications, and which additional style buttons are needed to access the font.
Navigate to where the "missing" fonts are installed on your computer, and double-click on each. The sample window that comes up has the name of the font in large letters at the top.
Two lines below this is an entry that says "Typeface name"; this is the name that shows in the font menu. More information: Style-linking is used with fonts of all formats in standard Windows applications. Why do Fonts not map correctly in documents transferred from macOS to Windows? Workaround: This is another aspect of the style linking issue described above.
