.AI vectors and text rendering wrong when PDF exported from InDesign


I have an InDesign file which has a placed logo linking to an .AI file. The logo looks absolutely fine in InDesign. I also have some large text using the font Open Sans which looks great in InDesign.

However when I export the file to a High Quality PDF both the image and the text looks pretty bad. I've gone through lots of settings on the export but I just cant figure out what the issue.

Here are some images showing the issues. All the images are set at 100% zoom in InDesign and the PDF.

Logo high res .AI file.

Text enter image description here enter image description here

As you can see the image and text in the PDF look 'wobbly'.

Here's the general export settings I have for High Quality Print PDF. However if you need any more information just let me know.

You can try using a different PDF viewer.

I find sometimes the weird pixellation doesn't actually seem to be anything to do with the exported PDF but with the PDF viewer I use to look at it - so Google docs or Mac's Preview viewer can sometimes give me these results, but I'll then view in Acrobat or Reader and it'll look smooth!
