• Like the interior PDF, the software used to generate files can vary. Some best practices for covers are:
    • All cover PDFs should be a single-page portrait orientated file that include the back and front covers as well as the spine.
    • Make sure all fonts are embedded
    • Ensure the document includes bleed, 0.125”, in its setup dimensions for improved trimming. The provided template will include bleed in the preset margins. Make sure your PDF does not include trim or bleed lines in your file.
    • Images should be rendered at 300dpi
    • Vector images should be rasterized
    • When in doubt, flatten the entire document.
  • You can also distill a finished PDF/Postscript file using our Lulu Job Options in Acrobat Distiller.
    • If you find that your files printed with artifacts or errors, running the file through Adobe Distiller with Lulu’s Job Options often helps remove issues.
