preview files are for making the user interface fast and responsive. they're not required as part of a non-destructive workflow.Whisky-daveWhisky-daveSandman
Do you happen to know whether or not this preview file is a copy of the original file but 'rendered' at 72DPI rather than the final copy which is mostly likely to be 300+ DPI for printing ? A little like doing a preview of soemthing you want to scan.
DPI is irrelevant in this context.
So what is the point of a preview file, you've not explained that.
