Hi Bonnie,
Thanks for getting back to me!
So here are the things I’ve tried since my post:
1. Open .AI file in Photoshop (which rasterised the file), save as PDF and place in InDesign… Worked perfectly (if not ever so slightly jagged)!

2. Flatten all layers in Illustrator to see if the transparency and effects on the layers is causing the issue – no luck as flattening made the file look terrible.
Here is a screenshot of the .AI file in Illustrator set to RGB – https://imgur.com/a/ARPbw
Here is a screenshot of the exact same .AI file where I have just changed it to CMYK – https://imgur.com/a/WBs8k
It’s like the CMYK colour mode can’t handle all the transparency, clipping and gradient effects layered into the file…
You can see how nearly all the colours that ‘glow’ in the RGB version are just flat colours now in the CMYK and they reflect such a large size because the bubbles have flattened out to encompass their transparent ‘glow’ area…
This is what one layer of bubbles look like in the original RGB file under Isolation – https://imgur.com/a/IM3Ji
So as you can see, all of the bubbles have some kind of transparency/opacity/gradient effect on them (I don’t know what to call it) and then they are all layered together – so when the file is brought into InDesign or changed to CMYK it’s like it’s not handled properly!
With regard to placing the file, all I do is simply open a new document to the size I need (A4), turn on the grid and go to File > Place and choose my file and place it anywhere on the screen before aligning it with the page – so it gets placed at it’s full size (and then I resize if need be, but not in this case)… I never really place an image into a frame – I just create my backgrounds to the correct size and use File > Place to place it at full size anywhere on the screen.
Also as side note, this is the original .EPS file in Illustrator as was downloaded from Shutterstock – https://imgur.com/a/o81ya
And this is the same file, switched over to CMYK – https://imgur.com/a/kptoi
Do you have any more suggestions?
At the moment I’m going to use the Photoshop PDF in my background so I can at least keep working on the wider design and have the file ready to place in the right file once I’ve sorted this issue out…
Is there some kind of Illustrator forum that I can post this issue in as well? I’m really out of my depth here and I don’t know how to resolve this!
Thanks,
Sarah
