I have had the problem of picking up a document that had been created in Indesign CS5.5 processing to PDF out of Indesign CS6 and two lines of type and two lines of outlined type had 'disappeared' when run to a PDF.
I spent some time investigating layers etc to no avail. When I eventually processed the document out of CS5.5 to PDF the result was exactly as appearing on screen in Indesign.
Does anyone know of this discrepancy between 5.5 and 6 or am I doing something wrong?
Is it interactive PDF or the Print PDF ?
Are you using the same settings in Cs6 that is in Cs5 ?
also, are these items on the master page ?
