Quiroga Serif began in 2007 with the name Quadratta Serif. This typography was designed for continuous text, legible at medium and small sizes, with great saving of space, optimized for 6, 8, 10 and 12 points. The morphology is a mix between tradition and innovation; it has a vertical axis, thick serifs, tall x-height, light modulation and a lot of internal space between letters: key to improve legibility at small sizes. Formally, my idea was to make a serif type that had a unique color, this is visible due to the light modulation. This is also complemented with the incorporation of not common, alternative signs. Some parts of the letters that are usually curb or diagonal where made horizontal (for example: a, q, p, etc.), this makes the eye of each character to be wide and unique. The serifs (wedge type) suffered diverse variations during the process. At the begining they where thicker and ended vertically, but this caused a great deal of printing errors. And so we decided to modify them by giving them an angle to avoid visible errors in medium and small sizes. The ch, and ll ligatures where rescued because they are a part of our current spanish alphabet. The historic ligatures and stylistic alternates give different options to users who want different alternatives within a text. The accentuation signs were composed in a middle line above all signs to avoid visual shock. We also gave plenty of importance to small caps numbers, mathematical signs and currency signs so that the could interact well.
