Which of the following is NOT typically a characteristic of serif fonts?

The correct answer identifies that serif fonts do not typically have a clean appearance with no extra flourishes. Instead, serif fonts are known for their decorative features, which include the distinct small lines or strokes at the ends of their letterforms. This characteristic enhances their overall appearance and contributes to their traditional and elegant qualities. The presence of these flourishes can also add a sense of sophistication to the text.

Serif fonts, by their nature, are designed to guide the reader's eye along the lines of text, making them more legible in print and thereby reinforcing their use in printed materials. Their historical association with print media suggests that they are indeed considered more traditional, which is another feature that contrasts with the notion of having a clean appearance free of embellishments.

Understanding the characteristics of different types of fonts, including serifs and sans-serifs, is essential in graphic design, as it helps designers make informed choices based on the context of their projects and their intended audience.
