PDF Images Pixelated (was "baileyharriet")

Hi,

If in case the useful suggestions above did not help you out (which i think wil not be the case) then read this discussion: CC2018 exporting pixelated PDF – Adobe InDesign Feedback

After my first post I saw another post that shed some further light on this if you are using the latest version (CC 2018) of InDesign. According to the other post the way to deal with this is to trash your preferences and InDesign Caches.

To do so:

To delete old preferences:

For Macintosh Users: With InDesign closed Launch a Finder Window in column view and click on your home folder. With the Option Key pressed choose Library from the Finder Go Menu. Within the Library folder find the folder called Preferences and within it find the following two files and delete them: “Adobe InDesign” and “com.adobe.InDesign.plist”. When InDesign is next launched it will create new preference files and the program will be restored to its defaults.

For Windows Users: You can try the quick way of resetting on a PC which is to hold down Ctrl + Alt + Shift when launching InDesign and respond affirmatively when asked if you want to reset. There have been some recent reports that the window asking if you want to reset is not popping up but that the prefs are being reset anyway. If this works then great but if it doesn’t you may have to manually delete them.

To do so:

On Windows 7 and above the preference files are hidden. To find them go to the Control Panel and open Folder Options and then click the View tab. Then select “Show hidden files and folders” or “Show hidden files, folders or drive options” in Advanced Settings (you may be able to skip the previous steps with Windows 10). Then delete (or rename) the folder at the end of this path: C:\Users\<USER>\AppData\Roaming\Adobe\InDesign\<Version #>\<Language> for any versions that you have. Make sure that InDesign is closed when you do this. When you relaunch the program it will create  new preference files and the program will be at its default settings. You should do this for any versions that are there. After deleting launch CC 2018, if the launch is successful, create and save a test file and then quit the program to “confirm” the preferences. It also may be a good idea to reboot your computer after this is done.

Once you relaunch the program you can begin customizing it to your liking.

After you’ve reset up the program (make sure that no document window is open), it is a really good idea to create copies of your personalized “mint” preference files (make sure that you quit the program before copying them—that finalizes your customization) and use them in the future to replace any corrupt versions you may need to delete.

To delete InDesign Caches:

For Macintosh Users: With InDesign closed launch a Finder Window in column view and click on your home folder. With the Option Key pressed choose Library from the Finder Go Menu. Within the Library folder find the “Caches” folder. Within the Caches folder find and delete the entire file “Adobe InDesign”. I find that deleting the cache file completely leads to a lasting change. 

For Windows Users: On Windows 7 and above the caches files are hidden. To find them go to the Control Panel and open Folder Options and then click the View tab. Then select “Show hidden files and folders” or “Show hidden files, folders or drive options” in Advanced Settings (you may be able to skip the previous steps with Windows 10). Then delete (or rename) the folder at the end of this path: C:\Users\[User Name]\AppData\Local\Adobe\InDesign\Version [#]\<Language>\Cache.

When you export your pdf try using the Press Quality PDF preset (see screen shot) for the export and see if that makes a difference.
