Convert fonts to outlines
After converting fonts to paths, the output system no longer needs to load fonts, since the glyphs only exist as vectors in the PDF.
Although correctly embedded fonts in a PDF should generally not cause any problems, it is possible that only text previously converted into paths is required for the transfer of the files. This is still common in packaging and label printing. Under certain circumstances, a font may also prohibit embedding based on the license restrictions it contains.
In order to convert the fonts into paths, a predefined Fixup is provided.
Text exists in the document as text objects
A Check for the contained objects shows that the black text exists as text objects.
Open the Fixup window, search for "Convert fonts to Outlines" and execute the Fixup.
