In Relativity you can restrict users' access to produced document images.
1. Go to Administration . . . Workspace Details and click on 'Manage Workspace Permissions' on the console on the right.
2. Click on Object Security and then select the group whose security you want to edit.
3. Set 'Production' to 'NONE' - the cross-out circle.
Now when the user goes into the core reviewer interface he or she will not see the radio button option for produced image next to the option for extracted text.
