Running any of these conversions on test-good.pdf will result in a significantly smaller file size simply because all the textedit information is stripped out. I ran these processes on a 28pp production score (2.21.80, no textedit), and the file sizes are: 407323 requiem6.pdf → pdf2ps → 1774527 requiem6-2.ps → ps2pdf → 548498 (134.7%) requiem6-2.pdf 407323 requiem6.pdf → (DAK's suggested method) → ps2pdf → 409954 (100.6%) requiem6-ps2pdf.pdf 407323 requiem6.pdf → pdftops → 2219804 requiem6-to.ps → ps2pdf → 371264 (91.1%) requiem6-to.pdf The loss in quality caused by pdf2ps (only) is as before. Cheers, David.
