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.

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.

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.

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).
