Will try this in a bit.
What about the other processes which I have queried:
-Crop the pages
-Check the sequence of the pages that it goes from 1,2,3 and so on
-ad metadata to the PDF
-set view
-Making single PDF files over 1.5 MB smaller
-Fix white lines
-Make the final file as a PDF that is compatible with Acrobat 5 or later
