From the PDF metadata in the two PDF files: Creator: Adobe InDesign CS4 (6.0.5) Producer: Adobe PDF Library 9.0 Creator: Adobe InDesign CS5 (7.0.3) Producer: Adobe PDF Library 9.9 I should mention that PDF metadata is somewhat unreliable -- it's quite possible that the files were modified by some other software, without changing the metadata. The first one has both 8-bit and 16-bit CFF fonts embedded in SFNT/OpenType wrappers, with no other tables. The second one has just 8-bit fonts, which have 'CFF ' and 'cmap' tables (and no other tables). - Derek
