The idea behind the font called Chaco originated after testing the deficiency shown in road signs in Latin America.

The design began after a long documenting period. Throughout the various stages of the work,  there were several  tests and checks  conducted of the formal solutions implemented which, based on the results, would gradually be changed until we finally reached, in this way, its definite design. The original project for the font features three steps, namely: regular, light and bold, yet by making progress in the development, it was possible for us to perceive that by enlarging the black and thin variances, the family with 5 different weights could offer very good results in mass media, such as newspapers, magazines and television.

In order to expand its possibilities of utilization, the set was completed with italics and small capitals.
