Up to the 5.0 version of Indesign I have always created the pdf printing a postscript file (using the Adobe PDF PPD ), to be processed later in Distiller .
With the new computer running OS X El Capitan and InDesign 6.0 I can not find the Adobe PDF PPD .
Creating pdf with the command export InDesign is 100% reliable in the case of letterpress printing ?
I have had problems In the past in processing transparencies.
Thanks for your help.
Use the InDesign Acrobat PDF presets, if you haven't been given a spec by your printer use PDF/X-4.
Note, InDesign CS6 is not supported under El Capitan.
This is the preferred method for creating PDFs from InDesign, and gives you more options than just printing to a PDF.
