Maybe I am getting old (or already old)? I could have sworn, that it was possible in previous versions of Publisher to change the spread setup afterwards from e.g. "Print (Press-Ready)" to "Print". If I want to change the spread type I have now only the options "Print (Press Ready)" and "Presets". And "Presets" only contains "Custom".
If I open a PDF I get all the other options like Web, Photo and so on, but I am not able to save the new other choice. EDIT:, but I am not able to switch between "Print" and "Print (Press-Ready)".
