To set justification options:
1
Choose Justification from the Paragraph palette menu.
2
Enter values for Word Spacing, Letter Spacing, and Glyph Spacing:
•
For justified type only, enter values for Minimum and Maximum to define a range of
acceptable spacing.
•
Enter a value for Desired to set the spacing for both justified and unjustified
paragraphs.
Word Spacing values can range from 0% to 1000%; at 100%, no additional space is added
between words. Letter Spacing values can range from –100% to 500%; at 0%, no space is
added between letters. Glyph Spacing values can range from 50% to 200%; at 100%, the
width of characters is not scaled.
Working with composition
The appearance of type on the page depends on a complex interaction of processes called
composition
. Using the word spacing, letter spacing, glyph spacing, and hyphenation
options you’ve selected, Photoshop and ImageReady evaluate possible line breaks and
choose the one that best supports the specified parameters.
About composition methods
Photoshop and ImageReady offer two composition methods: the Adobe Every-line
Composer and the Adobe Single-line Composer. Both composition methods evaluate
possible breaks and choose the one that best supports the hyphenation and justification
options you’ve specified for a given paragraph.
The Every-line Composer
Considers a network of break points for a range of lines and
thus can optimize earlier lines in the paragraph in order to eliminate especially
unattractive breaks later on. Working with multiple lines of type results in more even
spacing and fewer hyphens.
The Every-line composer approaches composition by identifying possible breakpoints,
evaluating them, and assigning a weighted penalty based on these principles:
•
Highest importance is given to evenness of letter and word spacing. Possible break-
points are evaluated and penalized according to how much they deviate from optimal
spacing.
•
Hyphenation is avoided when possible. Breakpoints that require hyphenation are
penalized more than those that create uneven spacing.
•
Good breakpoints are preferred over bad breakpoints. After breakpoint penalty values
are identified for a range of lines, they are squared, magnifying the bad breakpoints.
The composer then uses the good breakpoints.
The Single-line Composer
Offers a traditional approach to composing type one line at a
time. This option is useful if you prefer to have manual control over how lines break. The
Single-line composer uses the following principles when considering a breakpoint:
•
Compressed or expanded word spacing is preferable to hyphenation.
•
Hyphenation is preferable to compressed or expanded letter spacing.
•
If spacing must be adjusted, compression is better than expansion.
