When Dupla was designed, its DNA shown the best of the typographic heritage from the XIX century types, the oldest san serif known, also named as “Grotesk”, a soft synonym for bizarre, unnatural weird. XIX century Germans' eyes were surprised, astonished by the formal strangeness that provoked the mutilation of the well known serifed types. But the skeleton and DNA are barely perceptible, an invisible part of the nature of objects. We are interested in the epidermis, the outer, the visible, which directly speak to the eyes, and Dupla tells us with overwhelming presence, that is a formal, traditional type, covered with a childlike sweetness, with slight curves, epidermic, sweetening even ink’s traps up. Frutiger said that Latin alphabet letter’s minimum skeleton is like a lock where you should fit all the letters you see, but that skeleton allows many skins. We use a different skin for every specific use. And Dupla’s skin points to how generous, how friendly it is; the sweetness of the big and good-natured. They do not feel very comfortable in low-cost airplanes company’s seats, but in the proper location with enough room, they'll fill the atmosphere with kindness. Do not ask for narrow columns, or terse captions in squalid sizes; do not ask for ridiculous “small print” in dark contracts where «The party of the first part shall be known in this contract as the party of the first part …» That’s not for Dupla. Large headlines, generous width columns to cover, rude pullquotes half-breaking columns, loud exclamations, great sizes, with black weights. It’s in the insultingly generous, almost obscene use where Dupla is felt. And if you consider this a obscene, gargantuan, typographical feast, Dupla brings you everything to demonstrate that quantity does not mean less quality. Multi-language support, Latin plus full coverage, complete sets of small caps, fractions, old numerals, modern, tabular, bonds and all the “gourmet” paraphernalia that Patau has accustomed us, after many years of work. If you want to be obscene and pass the censorship, use Dupla. Hedonism is just a venial sin.
