Tehnika Sofia is the visual identity of the Bulgarian publishing house “Tehnika” (Техника), a Sofia-based publisher of scientific and technical literature. The mark was created by Stefan Kanchev (1915–2001), the Bulgarian graphic artist widely regarded as the “father of Bulgarian graphic design” and the “master of the trademark.”
Design and History
Kanchev designed the Tehnika logo as part of his extensive work for Bulgarian publishing houses. Contemporary Bulgarian sources list “Техника” (Tehnika) among the publishing houses whose marks he created, alongside “Наука и изкуство” (Nauka i izkustvo) and “Просвета” (Prosveta).[1][2]
The publishing house itself was founded in 1958 and remains the only Bulgarian publisher dedicated to books, reference works, dictionaries, textbooks and study aids across all fields of scientific and technical knowledge.[3]
Kanchev’s career spanned more than 1,000 trademarks and symbols, and his work was recognized internationally. In 1967 he presented 23 logos at an exhibition organized by the American Institute of Graphic Arts (AIGA), and in 1994 he was named one of the ten best logo designers in the world by the International Trademark Centre in Ostend, Belgium, alongside Paul Rand and Saul Bass.[4][5]
Meaning and Symbolism
Kanchev’s approach to trademark design emphasized simplicity and expressiveness, elegance and memorability. He drew inspiration from Bulgarian folk art and visual heritage while building graphic systems of “stringent structure and mathematical logic” in his later work.[6] The National Academy of Art, which holds a collection of his original works, describes his trademarks as impressing through “imaginative ideas and aesthetic virtuosity.”[6]
Kanchev himself stressed the importance of continuity in trademark design, stating: “We should not think that the era begins with us… The preserved sign is precisely tradition.”[7]
Typography and Design
Kanchev drew all his work by hand, “to the last letter,” and was known for a successful connection between type and image, clean forms and original artistic ideas.[1] His later work, from the 1960s onward, moved away from ornamental rhythms toward a graphic system built on geometric figures and precise lines.[6]
While the exact date of the Tehnika mark’s creation is not confirmed in available sources, Kanchev was already an established institution in Bulgarian graphic design by the mid-1970s.[6] The logo remains part of his legacy documented in the “Logo Book Stefan Kanchev,” the first detailed study of his work, compiled by Magdalina Stancheva.[8]
