Yes, iText DITO has built-in Rich Text (RTF) and CSS support in the editor, allowing users to design form templates to look exactly how they want. For example, you can add custom fonts or images for company logos, consistent branding etc.

Fonts and images can be added to the "Resources" in the iText DITO editor, and saved together in the template package file. Additional customization is also possible by using CSS stylesheets.
