When creating a PDF with Adobe Acrobat Pro, use Lulu's Adobe Job Options (Available at the bottom of this page). After downloading to your computer, double click the icon to install the Job Options into your Adobe Acrobat Pro products.
If using Apache OpenOffice, follow the instructions here: How to make a PDF using Apache OpenOffice
If you are uploading your own PDF, follow these guidelines:
Our printers use CMYK color space for all color printing. We recommend using the CMYK settings when generating your files for color printing. If you use RGB color space, we will convert your file to CMYK color space when making a print ready file, so it is important to review the print ready PDF to see if there are any color discrepancies before the file goes to print.
For more information, see Recommended PDF Creation Programs.
There is also a community generated list of PDF Converters and Readers available in the Lulu forums.
