Answer. To date, IEEE Xplore®, the IEEE's online premier document delivery system, has presented conference proceedings as bitmapped images scanned from print. Distilled PDF has been selected as the required format because it presents significant quality improvements over scanned PDF. Font display is sharper, charts and photos can be shown in their original colors, and distilled PDF documents can be searched using Adobe Acrobat's built-in text-finding feature. These quality improvements add value to proceedings delivered through IEEE Xplore®, which is visited by more than 24,000 researchers daily. Source: IEEE

Answer. The following settings are required for IEEE Xplore® compliance:

• PDF Compatibility: PDF version 1.4 (Acrobat 5) preferred. This assures that Acrobat Readers 4, 5 and 6 will be able to open the document.
• Optimize PDF: Yes. This allows faster viewing of the first page of the file on the web.
• Print Resolution: 600 dpi. Better print output
• Color/Grayscale Images: Bicubic Downsampling at 300dpi. Create/scan color images at 300dpi or higher.
• Compression for Color Images: JPEG/Medium Quality. Ensures that loss of quality due to compression is not excessive.
• Monochrome Images: Bicubic Downsampling at 600dpi. Same quality as printed text.
• Compression for Monochrome Images: CCITT Group 4. To keep the PDF file size reasonable.
• Compress Text and Line Art: Yes. To keep the PDF file size reasonable.
• Subset all Font if less than 100% of the Font is used. Otherwise, embed the entire Font. This will ensure that all readers see the exact same document.
• Base 14 Fonts: Subset Adobe Base 14 fonts (e.g. Times, Helvatica, etc) or their equivalent (Times New Roman, Arial, etc.)
• Security: All security settings must be turned off. No passwords must be assigned.
• Links and Bookmarks: The final PDF should not have any links or bookmarks.
• Page numbers, footers or headers: The final PDF should not have any page numbers, footers or headers.

Answer. You can check if your document meets most of the requirements by opening:

File | Document Properties | Summary
File | Document Properties | Fonts
File | Document Security

Unfortunately, you cannot determine information about image resolution. The person preparing the document must ensure that images comply with IEEE requirements.

For your convenience, PaperPlaza has also implemented tests for Fonts and Security. You can test whether your file meets PDF version number compatibility, fonts and security requirements by uploading the file through Test your PDF document link.

Answer. Unfortunately, if your manuscript does not pass the PDF version number compatibility, fonts and security requirements; you will not be able to upload it. If you are having difficulty preparing your PDF manuscript, checkout additional resources on this website on preparing your document using T_EX/L^AT_EX or Microsoft Word.
