If you see this error when creating your book, then you will need to embed your fonts and re-upload the PDF. Beware, if they do embed, they will not print as they appear on your screen. Font embedding is the inclusion of font files inside an electronic document.

You may use any fonts you wish in your document, but you must embed the fonts in the PDF to ensure they print properly. The most common issue encountered when creating a PDF is your choice of font. All common text editing software (such as Word, Adobe, or Google Docs) allows you to create a PDF, but it is important to create your PDF with the correct specifications so that your file is accepted and correctly converts to a print-ready file. Please keep in mind that when uploading your book file to the Lulu Book Creator tool this should be as a PDF (Portable Document Format) file. Modified on: Fri, 17 Sep, 2021 at 9:52 AM
