De Morgen uses two main typefaces throughout the publication: a serif and a sans serif typeface. The paper uses the serif for the body text and headlines and the other for the nameplate, pull quotes, subheads, bylines and drop caps. De Morgen tends to use the latter typeface in red and bold, except for the drop caps, and the former for decks.
Headlines tend to be in bold and in the same typeface as the body text. They are also in lowercase letters.
The decks, separated by rules, are in a sans serif typeface and are in gray.
The cutlines are in bold and are in a serif typeface. They also range in where they are; some are to the side of the photo, while others are on the bottom of an image. Cutlines are also introduced with a red bullet point.
Pull quotes are in red and in a sans serif typeface. They are also slightly bigger than the subheads, bylines and body copy.
Subheads are red and in bold to create contrast between it and the body text.
De Morgen treats all of these aspects differently for contrast and hierarchy: The headlines, decks, nameplate and more are used to display the important information in a brief way, while the body text elaborates on that information. Once the reader moves past the information that is emphasized, his attention will already be on the body text.
It seems like the paper is using the more “fun” typeface to introduce information and draw the reader in, while using the serif typeface to make the news appear, well, newsy. The paper wouldn’t use the sans serif typeface for a story, captions or subheads. It seems to follow a guideline where it doesn’t use the latter typeface for long bodies of text.
