that's normal. Don't worry about it.
Going to IDML is the way to get CS5 or CS5.5 to open in Cs4.
When he saves it as CS4 it will jump back up in file size.
Mostly you are losing the previews. This is normal.
The bigger issue will be that text is likely to reflow due to changes in the text engine, and of course any new features introduced in CS5 or 5.5 will be lost.
IDML isn't actually downsampling any links or fonts, nor is it downsampling any effects.
it is not unusual for indesign files to become "inflated" from saving over and over again. happened in the old days with painmaker files.
if the OP was to take the CS5.5 file and do a save as with a different name and then make a comparison between the original and the latest save, is there a size difference?
to see if any data is "lost", open the IDML file in 5.5 and perform a comparison between the two files and see if there is a difference.
hope this helps.
And please….in the future please use a more descriptive subject line.
Everything here is an InDesign Question.
Of course... wasn't thinking about that before I posted!
P.S. Thanks guys for all the replies, and so QUICKLY! Wow... I will look into this further.
Ok, we printed both files and the 9mb idml file is significantly lesser in quality when printing. Any other ideas or help?
Thanks so much
The only thing would be the images are not linked to the idml version.
Open the Links Panel. Check for missing links.
You will need all the images on the other computer or server.
So how does it even print a "low-quality" image if the image isn't linked?
There would be no image at all from an IDML if the links weren’t present when opening the file.
I suspect that optimized subsampling is selected in the print dialog. Change it to all.
Eh yes good point.
The image frames would come up gray if the images weren't found.
the images should be "linked" that is - it's the same image file as used before as it's picking it up from the exact same location on disk.
If the image is not printing out great - again check the links panel and make sure the image links are working ok.
Ok, figured out what was going on because of you guys....
SOME of the pictures are not linked... some are just "embedded" into the publication. Not sure why the guy did that... but he did.
And that's why embedding images is not a recommended practice
