PDF's showing with no background in Chrome

[Jenny @ Hughes Pumps]

I am having some issues with PDF's missing their backgrounds when viewed in Chrome. They seem to work fine on all other browsers. The only thing that has sort of worked is exporting them as PDF/X-3. When viewed in Chrome the background remains but it shows ontop of all images (I will attach a few examples) is there anyway around this? 

I have tried flattening before exporting, this hasnt seemed to make a difference. I have also tried to remove transparancy within the background without any improvement. 

- HP65 T3 2023 General - This shows correctly on all other browers apart from Chrome, where it removes the background. 

- Hughes-Pumps-HP65-T3 - Background shows in Chrome but images are distorted. 

Any advice would be appreciated.

Sorry. Wrong attachement. General is attached. This shows correctly on other browsers but Chrome removes the background

Chrome is NOT a valid PDF viewer. The only program which can show all PDFs correctly is Adobe Acrobat.

I agree with Willi, but Adobe Reader (free) should also let you view PDFs correctly.
