Note:
Spacing options are always applied to an entire paragraph. To adjust the spacing in a few characters, but not an entire paragraph, use
the Tracking option.
4. Set the Single Word Justification option to specify how you want to justify single-word paragraphs.
In narrow columns, a single word can occasionally appear by itself on a line. If the paragraph is set to full justification, a single word on a line
may appear to be too stretched out. Instead of leaving such words fully justified, you can center them or align them to the left or right
margins.
Set glyph scaling in justified text
1. Click an insertion point in a paragraph or select the paragraphs you want to affect.
2. Choose Justification from the Paragraph panel menu.
3. Type values for Glyph Scaling Minimum, Desired, and Maximum. Then click OK.
Before (top) and after (bottom) glyph scaling in justified text
Glyph scaling can help in achieving even justification; however, values more than 3% from the 100% default value may result in distorted letter
shapes. Unless you’re striving for a special effect, it’s best to keep glyph scaling to subtle values, such as 97–100–103.
Use a flush space with justified text
Using a flush space character adds a variable amount of space to the last line of a fully justified paragraph—between the last word and an end-of-
story character from a decorative font. Used with nonjustified text, the flush space appears as a normal word space. In justified text, it expands to
absorb all available extra space on the last line. Using a flush space can make a dramatic difference in the way the entire paragraph is formatted
by the Adobe Paragraph Composer.
Before and after adding a flush space character
1. Using the Type tool , click directly in front of the end-of-story character.
2. Choose Type > Insert White Space > Flush Space.
The effect of a flush space isn’t apparent until you apply the Justify All Lines option to the paragraph.
