I'm an Adobe support person in the Middle East. I'm an Acrobat Certified Expert (ACE), Photoshop (ACE) and InDesign (ACE). I worked in the publishing and printing industry since 1997. I've been an Adobe Certified Instructor since 2004. I often provide consultation to Offset printers of the best practices on PDF handling in print jobs.   Over the years I had quite often complaints from Adobe users about their PDFs behaving slow, freezing, and having issue when printing these PDFs to the local printer machine. I often go online with the client to inspect the issue closely to find that these PDFs were generated from AutoCAD.   The PDFs contains CAD drawing with hundreds of layers, complex details including live text or outlined text in some cases. In all similar cases, the customer is on Windows platform, I usually ask them to share the file for my own testing, however, I use a high end Mac mahine, I don't experience the problem which the owner of the file had on their Windows machines. The thing is those users owns hundreds of Acrobat Pro licenses on their premises, and yet, sadly they're willing to go for an Acrobat alternative that runs faster eventhough if the alternative lacks features such as live collboaration or e-Sign since all they want is to have a fast and responsive PDF experience!   I saw a couple of Autodesk help pages that discusses this issue, Autodesk provided some workarounds including switching to an alternative PDF reader other than Adobe's, but also have suggested flattening transparencies in the PDF among other suggestions. Now, I cannot tell a customer to switch to an alternative PDF reader, and I don't expect each user to apply technical remedies such as flattening transparencies as not every one would know what is transparency in the first place.    The reason why I mentioned my credentials on top is that when I speak to an Adobe customer who's working on major projects worth Billions of dollars and have 300+ Acrobat licenses. This client challanges us that Acrobat is not a good application for printing a PDFs and the proof is that a PDF generated from AutoCAD takes half an hour in the spooler before the laser printer spit out the single page PDF, while the alternative PDF reader prints the same PDF faster as expected. This complaint came from so many customers already and I have reiterated to Adobe users over and over that I have some work-arounds, yet this became unconvicing process of why an Acrobat users have to go through so much to fix the PDF that was generated from AutoCAD as stated above. Note. Users who complained about the slow performance PDFs have used the recommended Adobe PDFMaker driver to generate the PDF.   Any directions to solutions that I may have missed is welcome.   ...
