Which composer looks at only one line at a time when determining line breaks?

• A. Adobe Single Line Composer
• B. Adobe Paragraph Composer
• C. Baseline Grid Composer
• D. Line Breaker

Answer: (A)

Line breaks are chosen differently depending on which part of the typesetting system is doing the work. When the decision is made by looking at only the current line, it’s designed to be fast and localized, updating that single line without reflowing the entire paragraph. This behavior belongs to the Adobe Single Line Composer. It analyzes the width of that one line, including font metrics and potential hyphenation, to determine where to break before wrapping to the next line. In contrast, the Adobe Paragraph Composer considers the entire paragraph at once, optimizing line breaks across all lines to achieve the most even right edges and spacing overall. The Baseline Grid Composer focuses on aligning lines to a baseline grid for vertical rhythm, which can affect line placement but isn’t defined by analyzing one line in isolation. Line Breaker isn’t the standard term for this per-line approach. So the one that fits the description is the Adobe Single Line Composer.
