I just checked this site, and here's what they say;
Licensing Options
Standard User License
A Standard User License is issued with individual font purchases. It licenses a font for use on up to 5 CPUs and one(1) printer within an organization. The Standard User License is best suited for individuals and small organizations or in instances when only a limited number of individuals will need access to a desired typeface.
Font Embedding, Streaming and Web Server License
These licenses are for commercial publishers or web designers who wish to use fonts in ways beyond the scope of the Standard User License. For example, to embed fonts into eBooks or other commercial products, to embed fonts in websites that allow for content editing, or web servers that use fonts in their end user applications. For complete information on these Licenses, go to
www.fonts.com/embedding.
Unfortunately, it doesn't really make any mention of using fonts in artwork.
Hope that helps somewhat...
