Using the Experts Adobe sells a number of Expert-set typeface collections. These collections contain many of the less frequently used characters that add a professional look to your documents, including old style figures, small caps, ornaments, and ligatures. For example, you can use f-ligatures, which eliminate awkward character combinations. Compare the ff, fi, fl, ffi, and ffl ligature combinations in the second line with the individual characters in the first line. When you are setting numbers with lowercase text, it is best to use lowercase numbers.
Numbers come in upper- and lowercase versions.
The lowercase versions are often called old style figures, and they contain characters with ascenders and descenders. Uppercase numbers look fine in spreadsheets and in uppercase text, but look too large in body text. Small Capitals Smaller versions of regular capital letters, called small capitals, are designed to be visually appealing with lowercase characters in a typeface, that is, they are drawn to have the same typographic color as the lowercase. Some applications allow you to apply a small-capitals style to your text. This usually means that the application reduces the point size of full caps to about the height of the lowercase.
