JY DÃ©cennie Express was developed as a sans serif workhorse complement to JY Décennie. The basic roman design shares characteristics, and in some cases, characters (e, o, and others) with the serif version, making JY Décennie Express work particularly well with its progenitor.
The design is friendly and approachable, as opposed to stark (the effect one usually has with Helvetica and other over-used typefaces). On closer inspection, straight lines blend into curves on the outlines: the characters are in fact complex but appear simple.
The principal departure with the serif version is the presence of a Heavy weight. It works well in text applications as well as at large sizes.
All typefaces have been fine-tuned, with the text fonts featuring 2,200 kerning pairs each.
