Tac typeface by Afrotype is deeply rooted in the history of Festac '77, one of Africa's most significant post-colonial cultural events. The design process began with an in-depth study of the original lettering's construction and contrast model. According to Afrotype, the team "deduced that the contrast model is translational" and focused on crafting the characters using three main shape elements "80-degree broad brush straights, 180-degree broad brush curves , and then for horizontal strokes, 90 degrees." These guided the iterative design process, which involved transformations like reflection and mirroring.
