Compression Error with White sections showing as Black

[emma5DD1]

Hi,

I'm trying to compress a PDF that was created with Adobe illustrator using Adobe's Free Online Compression tool. On the whole it works, but there is one Block/Section that is White on the design, which turns Black when it's compressed. This happens regardless of the High, Medium, Low compression choices selected.

Any ideas?

Thanks

Em

Here is a screen shot showing what happens when viewing the file in Mac Preview... The Area disapears completely rather than showing in black.

The image on the left (Mac Preview) is incorrect, the image on the right is correct (Adobe Acrobat), yet its the same file. First time i have ever seen this issue.

Hi Emma, 

Thank you for reaching out and sorry about the trouble.

Would you mind sharing the original and compressed document with us? We would like to check them and investigate this issue.

Without checking the document we cannot comment on what exactly creating the issue.

Thanks,
