He began his art studies at the school run by the painter Pere Borrell, but at the same time also started a degree in engineering. When he graduated he went to work for the Maquinista Terrestre i Marítima, but by that time he was already contributing to several newspapers.

Although he dedicated himself to the academic world of engineering, he never gave up his artistic activities and specialised in cartoons for magazines and posters. In 1898 he started contributing to the magazine L'Esquella de la Torratxa and presented some of his work at the Barcelona Fine Arts Exhibition. Shortly afterwards, in 1902, he founded the magazine Cu-cut! - where he created the figure with the typical Catalan cap which has become a recognisable character in the cartoons of the Catalan autonomy movement - and was its artistic editor until 1912. Never the less, he kept up his contributions to other magazines, such as Patufet and Virolet, as well as to scientific and technical journals.

He signed his cartoons with a sort of hieroglyph representing his surname: the drawing of a heart ("cor" in Catalan) with the syllable "NET" inside it.

At the end of his career he founded a photogravure factory which later became Unió de Fotogravadors.
