The Secretary of State is the custodian of the State Flag and Seal artwork.  In addition, that agency provides information on fonts, pantone colors, etc. used by state agencies.  Usually, each agency has a Communications Officer that keeps the information on file for media, or just such use.  Contact your respective Communications Officers to find out more on agency artwork.

Each governor changes the fonts on letterhead used on documents along with an occasional tweak to the state seal.  OTS Production Support Services (which includes State Printing) can be a good resource to insure that the correct fonts and assests are used.
