About composition and composition methods

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 that you selected, Photoshop and ImageReady
evaluate possible line breaks and choose the one that best supports the specified parameters.
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 specify for a given paragraph.
The Adobe Every-line Composer
lines in the paragraph to eliminate especially unattractive breaks later on. Working with multiple lines of type results
in more even spacing and fewer hyphens.
The Adobe Every-line composer approaches composition by identifying possible breakpoints, evaluating them, and
assigning a weighted penalty based on these principles:
The highest importance is given to evenness of letter and word spacing. Possible breakpoints 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 Adobe Single-line Composer
is useful if you prefer to have manual control over how lines break. The Adobe 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.
