Available in select languages. CAD and geospatial functionality have been greatly enhanced in Adobe Reader 9. For instance, CAD designs or geospatial maps that have been converted to PDF offer Adobe Reader users access to CAD features, such as dimensions, or map features, such as longitude and latitude, for powerful collaboration and interaction. Adobe Reader 9 provides new digital signature functionality for an improved user experience. The new version also adds support for bit AES encryption.
Adobe Reader 9 significantly improves the viewing of XFA forms for accessibility, while providing greater screen reader support. This product is capable of installing any combination of supported languages. So, for example, you can install French, German, and Spanish simultaneously and then have the capability to switch among those languages within Adobe Reader. The user interface changes to the appropriate language on the fly. Now open the Adobe Acrobat program on your computer.
Next on the window that opens locate and select the file you want to optimize. The Adobe PDF optimizer will open your PDF file and then let you choose amongst three optimization options; Optimize scanned pages, reduce file size and advanced optimization. If you are working on a PDF file you created from scratch not a scanned document then select advanced optimization for the best result if your PDF file has many images and graphs. The optimization window will open where you will select the optimization settings you want and then click ' Ok ' and then save your document.
Alternatively, if your PDF file is made up of mainly of text then simply select the ' Reduce size option ' and then follow the onscreen prompts to change settings and then save your file.
Your file has been optimized and is now much small and can easily be sent via email and even uploaded to a website even those with limited bandwidth. If on the other hand your PDF file is created from scanned documents then the best optimize it is for you to select the ' Optimized scanned pages ' option. This is because scanned PDF files behave differently from a PDF created from a text document and will need a different approach in optimizing it.
Once you hit the ' Optimize scanned pages ' button, an optimization window will open. You can also audit space usage of a PDF in the Content pane. From the Content pane options menu , choose Audit Space Usage.
From the functionality perspective, both the options are the same. Choose the location to save the file and click Save. Select the version compatibility that you need, and click OK. In the Output Options dialog box, specify your folder and filename preferences, and click OK.
To use the default settings, choose Standard from the Settings menu, and then skip to step 6. The options available in panels vary depending on this choice.
Select the check box next to a panel for example, Images, Fonts, Transparency , and then select options in that panel. To prevent all of the options in a panel from executing during optimization, deselect the check box for that panel. Optional To save your customized settings, click Save and name the settings. To delete a saved setting, choose it in the Settings menu and click Delete. The Images panel of the PDF Optimizer lets you set options for color, grayscale, and monochrome image compression, and image downsampling.
Reduces file size by lowering the resolution of images, which involves merging the colors of original pixels into larger pixels. Note : Masked images and images with a size less than by pixels are not downsampled. Reduces file size by eliminating unnecessary pixel data. ZIP is the better choice for illustrations with large areas of solid, flat color, or patterns made up of flat colors.
For JPEG compression, you can also specify lossless so that no pixel data is removed. Compression for monochrome images is lossless, except for JBIG2 compression, which provides both Lossy and Lossless modes of compression. Available only for JPEG format. Divides the image being compressed into tiles of the given size.
If the image height or width is not an even multiple of the tile size, partial tiles are used on the edges. Image data for each tile is individually compressed and can be individually decompressed. The default value of is recommended. When selected, if the image setting will cause an increase in file size, the optimization for that image is skipped.
Text in these languages is replaced with a substitution font when viewed on a system that does not have the original fonts. The Fonts panel of the PDF Optimizer contains two lists for fonts: fonts that are available for unembedding, and fonts to unembed. To unembed fonts in a document, select one or more fonts in the Embedded Fonts list, and click the Unembed button. If your PDF includes artwork that contains transparency, you can use presets in the Transparency panel of PDF Optimizer to flatten transparency and reduce file size.
Flattening incorporates transparency into corresponding artwork by sectioning it into vector-based areas and rasterized areas. PDF Optimizer applies transparency options to all pages in the document before applying other optimization options. If you click the Make compatible with pull-down arrow and choose another program version, the Settings name in the upper left of the dialog box changes from Standard to Custom, as shown in Figure 5.
Click a category label to display settings at the right of the dialog box. The optimizing options vary according to the program version selected in the Make compatible with list.
Figure 6: Customize settings to balance document quality against file size. Name and save the optimized file. Check the effectiveness of your optimization by reopening the PDF Optimizer and re-running the audit. Optimizing the example file audit results are shown in Figure 4 using the default Acrobat 8. Images dropped from 37kb to just over 9kb, while fonts dropped from 84kb to less than 2kb. The overall file dropped from kb to just under 20kb. Click OK to process the file.
When I go into File Properties, there are 6 fonts listed, some of which are embedded. I would love to unembed the fonts, but since they are not listed in Optimizer, I am not able to. What can I do?
