Apparatus SIL Bold الخط

Apparatus SIL Bold from SIL International is a free high-contrast serif. Its upright letters combine broad main strokes with fine hairlines and crisply bracketed serifs, producing a formal, bookish silhouette with firm traditional proportions.

Editorial titles are its strongest use, especially for history books and literary magazines that benefit from the pronounced changes in stroke weight. Museum posters, academic event materials, and heritage packaging also suit its authoritative drawing, which can become the recognizable core of an institutional or product identity.
