Originally released in 1987, Charter incorporates three important features: compact set width to give economical copyfit; generous x-height to give readability at small point sizes; and sturdy open letterforms to give reliable reproduction at both typesetter and laser printer resolutions. The design brings a clarity and freshness to everyday documents, such as newsletters, textbooks, directories and technical manuals, where the reader's concentration must not be interrupted by unfamiliar letterforms but where typographic dullness can itself impair comprehension.
