CJK composition
InCopy supports four methods developed for typesetting, including Adobe Japanese Single-line Composer, Adobe
Japanese Paragraph Composer, Adobe Paragraph Composer, and Adobe Single-line Composer. Each Composer
evaluates possible breaks in CJK and Roman text, and chooses those that best support the hyphenation and justification
options specified for a given paragraph.
The Adobe Paragraph Composer
Considers a network of breakpoints for an entire paragraph, and thus can optimize earlier lines in the paragraph in
order to eliminate especially unattractive breaks later on.
The Paragraph Composer approaches composition by identifying possible breakpoints, evaluating them, and assigning
a weighted penalty to them based on such principles as evenness of letterspacing, word spacing, and hyphenation, or
Roman words set to a language that supports hyphenation dictionaries.
You can use the Hyphenation dialog box to determine the relationship between better spacing and fewer hyphens.
Adobe Japanese Paragraph Composer
Adobe Japanese Paragraph Composer, like the Paragraph Composer, evaluates breaks (where to wrap to the next line)
in units of paragraphs. If characters are added to or deleted from a paragraph specified for this Composer, mojikumi
may be modified on the line before the edit point because the Composer re-evaluates mojikumi in the whole paragraph
in order to optimize it.
The Paragraph Composer approaches composition by identifying possible breakpoints, evaluating them, and assigning
a weighted penalty to them based on such principles as evenness of letterspacing, word spacing, and hyphenation.
Paragraph Composer evaluates breaks for the entire paragraph and fits mojikumi on the basis of character spacing,
word spacing, and rules for even hyphenation. For CJK text, this is calculated as the difference between the actual value
of mojikumi aki inserted for full justification or kinsoku processing and the optimum value set in the Mojikumi
Settings dialog box. When the aki necessary for full line justification is more than the maximum aki, or when the aki
necessary for kinsoku processing is less than the minimum aki, an H&J violation occurs.
The Adobe Single-line Composer
Offers a traditional approach to composing text one line at a time. This option is useful if you want to restrict
composition changes from late stage edits, and you don’t care about some lines in the paragraph being very loose while
others fit perfectly.
Adobe Japanese Single-line Composer
Adobe Japanese Single-line Composer applies mojikumi by evaluating line breaks one line at a time, in the same way
as Single-line Composer.
