I say partial as it shrinks the PDF to about 2/3 the size, which is still much larger than people achieve with Adobe's software. 1) Export as an EPS file - this makes a massive 18 GB file for the above example 2) Use the tool ps2pdf which uses Ghostscript. I would add, this was done on Mathematica 6.0.2 on a machine running Solaris x86, on an Intel CPU. This involved the modifications (posted on here some time back) to run on an Intel CPU. However, I very much doubt this would change the result. But running ps2pdf on Windows Linux or Mac might well give differerate results.
