How to reduce size of PDF rendered from Vault

Below are the steps that can be followed to make the PDF output smaller and more legible.
1) Use fileinfo (you'll find this file utility in the Server\tools) to determine what resource set the document is using.
To know the Resource Set, only parameter that fileinfo takes is name of .drd file.
 Fileinfo <..>/Server/DocData/xyz.drd
2) After you know the resource set, from the command prompt go into that resource set directory - server/distrib/<resourceset>    
3) Execute afpsubstitute > fonts.ini
4) copy fonts.ini to Server/render/<resourceset> as well
5) Restart all render and router services
6) Render the document to PDF and examine the results.
