Irma Slab is a geometric capital-only slab serif typeface suitable for display purposes. Irma Slab is both resolute and delicate depending on the choice of the weight - 9 of them, ranging from Hairline to Black.
No overshoots & low accents
The round characters of Irma, such as O, C and G, have no overshoots (the degree to which the highest and lowest points exceed the flat baseline to achieve the optical effect of being the same size), which allows setting text with no space between the lines, as all letters are equally tall. When a special OpenType feature is applied (Stylistic Set 5), some accents above letters are lowered to eliminate space between the lines.
Another OpenType feature (Stylistic Set 2) allows automatic highlighting of text when no other font style or colour is available, simply inverting the text to negative forms.
Inspired by the principles of the Arabic alphabet, Irma provides different conditional letterforms, depending on whether characters occur at the beginning, middle, or the end of the word. Letters can have four different forms (initial, medial, final and isolated). The choice of these forms is controlled by a powerful OpenType feature (Stylistic Set 1), which allows creation of typographic patterns using the negative spaces of the letterforms.
Irma includes over 200 discretionary ligatures to make the setting of text even more compact and unique. With the help of the sophisticated contextual substitution offered by OpenType technology, using these ligatures is easier than ever before.
Irma was designed in 2009 by Peter Biľak.
