Efforts have been made to improve reading products in terms of comprehension, retention, memory, reading speed, among others, and their effectiveness in association with certain orthotypographic uses, but little has been studied the incidence of ambient lighting on paper, material in which the writings are involved and their effectiveness and/or limitation in performance and permanence in readers, especially in people with visual disability. This investigation studied the level of luminosity of substrates for printed texts in order to optimize the reading process in university spaces. Three samples of common use paper were selected, and their level of luminosity was measured through a lux meter in a natural and artificial environment. The averages of brightness of the coated paper were compared with those of press type in the morning (p = 0.005) and in the afternoon (p = 0.002) and a significant difference was observed in favor of the first; and a significant difference also at noon in favor of offset (p = 0.002) when comparing its brightness averages with those of the press type (whose index was lower in all cases). The results expose the level of luminosity of these substrates and their knowledge implies improvements in terms of well-being for the user in conditions of temporary or permanent use of the object according to its reflectance index.
