Likely when your boss downloads the ID file he is not downloading the images. InDesign will then use the embedded low-resolution preview image. The images need relinked in that case.
Try saving as a packages, upload that folder structure to drop box and have him download that whole folder structure, open the ID file and relink.
I did try saving as a package but apparently it didn't work any better. I may have missed a step though. Would he have to go through the re-linking process, or would I re-link prior to sending it?
Yes, he would need to relink.
Where are the images stored for the original publication(s)? When you package, all those images should be collected into a folder wherever your save the packaged file. When that folder structure is copied/moved (new machine, different location on a local drive, dropbox, etc), ID will need to relink them again when the publication is opened.
But the whole folder structure needs to be copied to the boss' computer, not just the ID file. That is if y'all are not set up to use the exact same dropbox folder system and you are working from it.
Gotcha. Thank you so much!
If you go to Window>Output>Preflight. It will show you what you are missing in your files.
You can also go to Window>Links. Find the picture in question and it will give you a status (?) if you are missing any image. At the bottom of that same Links panel you will see tiny icons that say Relink, Go to Link, Update, you can replace or find any that are missing.
To find out if your images are high res for print, you can go to Window>Info and select the pictures in question. It will give you an effect ppi when you click on your picture. If it's not at least 300 it's not high res.
After you fix all that, then package the file.
Another way to recommend to your boss to relink the images is to:
- Open the Links window
- Select the first link in the list by clicking on it
- Scroll down to the last link in the list
- Hold the Shift key and click on the last link (this will select all of the links between the first and the last)
- Go to the fly-out of the Links window and select Relink to Folder
- Navigate to the images folder that was created when you packaged the files
Any images that are in the folder that have the same names as the images in the links window will be relinked in one go, and there shouldn't be any missing links if you packaged correctly.
