I've been asked to share InDesign files with a customer who is using a windows computer (I'm using a mac) - i've been told if the windows computer opens the InDesign documents, this may effect the artwork. (The customer is to make content changes and export as pdf - they will not be editing layout their end) Is this true? / how do i get arround it?
The best way to share a file with another person is to use File > Package. This collects all of the assets (images and fonts) and puts everything they need into a single, new folder. Hand off the new folder and they will have everything they need.
Who comes up with this nonsense? As mentioned the only potential issue is fonts. The only way artwork might change would be if you opened the file in a different version of InDesign. Platform is irrelevant.
