May we modify TypeTrust fonts with a font design application like FontLab or Fontographer?
Yes, but only for your personal or internal business use, which does not include commercial use, reproduction, or distribution. If you present to a client any modified version of a TypeTrust font, that version is subject to all the terms of the EULA and may require a License Extension or Commercial License depending on your intended use. Aside from aesthetic modifications, if you find technical fault with any TypeTrust font, we will make any reasonable technical improvements. Our philosophy is that a typeface is always in development, but eventually meets common standards of usability and publication. If your personal standards merit further development of a TypeTrust font, we look forward to hearing your feedback.
