White lines on interactive pdf

Hii guys!

I have a digital planner which is basically a hyperlinked pdf.

It's for screen obvs so ideally needs to be RGB.

I've been exporting using a variety of combinations on the very limited export options on the interactive pdf settings

lossy/lossless at medium quality 150ppi  - all of them give me these weird litte white lines on my artwork - like boxes around elements that disappear and reappear when you zoom in

At the moment the document is built entirely of eps files placed into indesign - I've found that placed .jpg/.png/.pfd images create enormous files and really poor quality pixellated text which I'd like to avoid. The EPS files are each under 5mb.

I understand this weird ghost line thing is common and with print files and is to do with the way the images are flattened on export and doesn't show up on the actual printed output.... which is great, but as this is specifically for use on an ipad, it would be really great if I can get rid of 'em. 

Has anyone got any suggestions for alternative ways of exporting this? I've been faffing with it for 2 weeks and right now I'm at the end of my rope with it. 

Thanks in advance!
