1. 1 PDF Optimizer J. Poole

2. Optimizer, TM Knoxville, October 2007, J. Poole 2 Documentation The documentation on the JACoW website concerning use of the optimizer contained an error until July 2007 – my fault and it is now fixed. The screen shots of the parameters had some of the default settings, rather than what is required. The principle is that the settings should be the same as the distiller settings.

3. Optimizer, TM Knoxville, October 2007, J. Poole 3 Using the Optimizer The reason to use it is to convert all PDF files to the version level required for publication on our website – PDF1.4 (Acrobat 5 compatibility) This is necessary because a number of files end up with the wrong version.

5. Optimizer, TM Knoxville, October 2007, J. Poole 5 Save As vs. Save Discussed at TM in Trieste 2006 Conclusions are still the same - PitStop 7.0 and Acrobat were used again in a test in September – carry on using ‘Save As’ and fix things later using Optimizer. If you do some things with PitStop on an Acrobat 5 file and use ‘Save As’ EVEN WITH THE SETTINGS FROM THE PREVIOUS PAGE, the PDF file is saved as Acrobat 7 If you use ‘Save’ this is not the case on a PC. On a Mac it is slightly more complicated but the result is the same – you end up with a mixture of versions. Furthermore – ‘Save’ does not optimize for web view which leaves you with files which can be 50-100 times larger than they need to be.

10. Optimizer, TM Knoxville, October 2007, J. Poole 10 Fonts - comments It is not clear to me how this will work in the batch job. It could cause problems for IEEE publication if the fonts are not embedded. We want fonts to be embedded as well because it means that the files will display well on everyone’s machine (in principle).
