Jasper Rietman's illustrations look great on the printed page. Actually, they look great on the screen as well. His work is bold and colorful, and his cartoon and comic book-inspired aesthetic has a way of making the images' meaning almost immediately apparent. Rietman's work with color has a lot to do with this immediacy. Many of his illustrations feature a solid color background, which gives them a weight suitable for a web or magazine layout.

In addition to his editorial work for clients like The New York Times and Bloomberg Businessweek, he also maintains a triptych, wordless comic series aptly called TRI/P.
