Content Upload Validation

What Is Content Upload Validation?

Content Upload Validation is a PDF file analysis tool that can assess the quality of cover and interior files uploaded within an IngramSpark account.

This tool allows Lightning Source to look at the PDF content uploaded and provide on-screen feedback to you about anything that could be detected in the file that could prevent or delay your book from completing the title set up process.

When you submit a revised file for a book you need to make changes to or you set up a new title and upload the cover and interior files through your Lightning Source account, you will see the message CONTENT UPLOAD VALIDATION, while this tool checks your files for technical issues such as:

  • Fonts not embedded
  • File contains transparency
  • Low resolution images
  • Spot colors used
  • Damaged PDF document
  • Color space used
  • Password protected file

If your files pass the Content Validation process, it does not guarantee that your content will pass through our file submission process without issues. If the Lightning Source premedia team finds a problem with the file(s) you will be notified by email of the corrections to be made. You can also access this information through yourLightning Source account when you see the "Title Processing Error" status for your book by clicking on the link. 

You will need to correct the files and upload them again. If corrected files are not uploaded, we cannot complete your title set up work.

File Fix Services

Some of the items detected by the Content Upload Validation function will be things that Lightning Source can attempt to fix for you at no charge. 

When this happens, you’ll see the following note in the on-screen messaging:


Corrections to some errors cannot be 100% guaranteed. For this reason, we strongly recommend reviewing a printed copy of the final book when taking advantage of this free correction service.

If Lightning Source is not able to offer a correction to an error found, for example where fonts are not embedded, you will not see any messaging offering the free correction service. Instead you will be asked to replace the file uploaded with your own corrected version.

When the Content Upload Validation function is performed, your files have not yet been released to Premedia for processing, so, there is no cost associated with replacing a file (revision) and performing a new Content Upload Validation.

You can replace and validate files as many times as needed. You are not charged a revision fee unless you have accepted the eproof and then upload revised files.

Please contact the Lightning Source support team if you have any questions about the file correction information you receive:
