Sardinka is a contemporary, humanistic, sans-serif font known for its ink traps. According to the Czechoslovak classification of typefaces by Jan Solpera, the font falls into the category of linear sans-serif static typefaces, specifically neogrotesque. The font is based on the details and smoothness of the curves of each letter. It is designed for printing purposes. The ink traps give the font its uniqueness, and at small sizes, the characters do not fill in. Typefaces referred to as neogrotesque can be dated back to the 20th century. The main inspiration for these typefaces is the statics of classical antiqua. Their characteristic elements include a vertical axis of shadow, an enlarged x-height, and horizontally terminated open strokes. Similar typefaces include ITC Franklin Gothic, Univers, Helvetica, Neogrotesk, and Imago.
