Not technically. The expiring campuswide web license for Verlag and Vitesse only covers web page copy (i.e., HTML text within pages), which means you are not required to update online PDFs, images, videos, or downloadable files hosted on your website. However, we recommend updating these fonts to Red Hat Display and Red Hat Text wherever they exist in digital and printed materials, as time and resources allow.
Keep in mind that PDFs should generally not be used as web content, for usability and accessibility reasons. For more information, read about usability and accessibility issues with PDFs, courtesy of the School of Medicine and Public Health.
