Slab serif typefaces have a rich history that dates back to the early 19th century, where they were primarily used in advertising, posters, and other display applications. In recent years, they have made a resurgence in web design and digital media due to their bold and distinctive appearance that stands out on screen.

The original PF Synch was released in 2006 as a contrasted slab with thick block-like serifs, but the new version introduces significant changes and improvements.

The new PF Synch features narrow proportions, offering economy of space for headline use. The typeface is now monolinear with wedge-serifs, and most inner corners have been rounded for improved readability. The shortened capitals and consistent geometry throughout the set of styles increase the typeface's versatility within body text, while providing a balanced rhythm when used in headlines.

One unique feature of PF Synch is the sharp cut at the joins, adding an industrial strength quality at heavier weights, while compensating for over-inking. The new version has been converted into a variable font, with numerous weight selections between the Light and Black weights, while still being offered as a set of 14 separate weights.

With six special OpenType features and multilingual support for all European languages, including Greek and Cyrillic, PF Synch is a versatile and reliable choice for any designer looking for a bold and distinctive slab serif typeface.
