Three-dimensional geometry remained the basis of his work until 1974, when he returned to the pictorial flatness of oil on canvas, performing a broad exercise in composition, colour contrasts and optical illusions. In 1970 he ventured into the fields of work by Muestra Española de Nuevas Tendencias Estéticas (MENTE group). That same year, he was chosen to design the official poster and medals for the European Swimming Championships held in Barcelona. In 1971 he designed a mural-like building facade in Barcelona.
In 1972 he travelled to the United States for the first time.
Interested in the idea of making art more accessible to society, Navarro Vives and some of his friends founded an art publishing house (Disform Ediciones).
