Hello! If you tick the implementation fonts embedded fonts, which I do use in the document and some other fonts (I learned this by opening the document in the archiver). They (other fonts) greatly increase the size of the document (up to 10 megabytes of unnecessary fonts). They are not needed as they are not used. Why to implement them? Make in the settings tab of the implementation of the fonts another check mark "to implement only those fonts that are actually used in the document.
