Fix font errors from InDesign
Find another free download of the font. Simply search in Google for "FONT NAME free". Then import the new download of the font.
Try importing both a .OTF and .TTF. If Option One did not work, try finding a different version of the font. On files-conversion.com/font/otf, you can quickly convert a font to a new file type.
Upload the font that you have. Manually change the font to the one you uploaded in Lucidpress.
Rename the font description and title to match Lucidpress in Font Forge. Download and install the free version of the program.
Click File > Open and select your font. Click Font Info, edit the name of the font under "General" and "Postscript". After clicking ok, go to File >Generate Font to save it.
If the font is used in minimal places, you can take a screenshot of the original text and insert it as an image. For example, this can work if a tagline is written in a unique font.
If none of these options work, search for "FONT NAME substitute". Generally, you can find a font that is similar to use in Lucidpress.
