The specific kind of contrast that Epoca Classic accentuates is stroke contrast—the difference in weight between the thick and thin strokes. The greater the difference, the higher the contrast. The more the strokes appear the same weight, as in Epoca, the lower its contrast, or more monolinear it becomes.
Epoca Classic’s heightened contrast adds a touch of sophistication to the design, and relieves a bit of the tension on the horizontals when printed at text sizes. This phenomenon is particularly visible in the heavier italic weights.
