Blanks In Overprint Preview

Are there any locked objects? (Object> unlock all on spread)

Here is one scenario that might explain what's happening, you have an overprinting object set to a white spot color, it looks fine in InDesign with overprint preview on, the exported PDF looks fine in Acrobat (with the Use Overprint Preview preference set to Always). A jpeg exported from InDesign will not show the overprinting, a PDF viewed in Reader will not properly show the overprinting spot color, regardless of the overprint preview setting.

If none of these apply, you might try exporting your InDesign file as an IDML, then open and save it.

Please see the images below, i do apologies but I have had to blank the content out because of the personal content and personal details.

I tried to re-create the issue but i couldn't.

There is full content in the black areas white space in the corner will be an image, which is not placed yet.

In overprint view it looks like this with the the top half content disappearing

Thanks guys they have opened it in adobe reader, i have asked them to try chrome etc and see if the problem persists but haven't had a reply yet.

My thoughts is it can't be just there system because when i export as images the first page appears as blank, will upload images shortly.

Thanks for the responses.

You should ask the recipient which Software he is using, Program Name, Version.

Only Acrobat is able to show all forms of PDFs correctly.

They are receiving this message "a drawing error occurred"

That points to some kind of error / trouble on their end, specifically on their software / system.

See:

"A drawing error occurred" Error

and

Acrobat Pro XI 'a drawing error occured'; error processing page. An internal error'! (Installation & updates)

Best regards

You should show us the view with overprint preview on and off. Also tell us what program the recipient is using to view the PDF. Not all programs that view PDFs show things like overprint or transparency effects the way Acrobat does.
