Flattener Preview Test various flattening scenarios and preview the results. The OK and Apply buttons have very different functions: OK exits the Flattener Preview and stores the results for future previews (if the settings have been saved as a named preset). Apply processes the settings in the Flattener Preview dialog box, and flattens the file accordingly. You cannot undo Apply, but the file is not permanently altered until you choose File > Save. Applying Flattener Settings Keep in mind that applying flattener settings is the same as flattening transparency-a permanent change that cannot be undone. Alternatively, you can flatten transparency in a copy of the document-without affecting the original PDF file-using PDF Optimizer; see the next section "Flattening Transparency Using PDF Optimizer." To apply the flattener settings to the PDF document: 1. In the Flattener Preview dialog box, specify flattener settings. 2. In the Apply To PDF area of the dialog box, select the page or pages to apply the flattener settings to. 3. Click Apply. You cannot undo this operation. Flattening Transparency Using PDF Optimizer To create a copy of the PDF file with flattened transparency, use the Transparency panel in PDF Optimizer. PDF Optimizer applies transparency settings to all pages in the document before applying any other optimization settings you have selected. To flatten transparency using PDF Optimizer: 1. Choose Advanced > PDF Optimizer. 2. Select the Transparency option in the left column. If the document has flattener settings associated with it, Acrobat uses these settings as the initial values in the Transparency panel. Otherwise, it uses the settings last used in the panel. 3. Choose a flattener setting (usually High Resolution). 4. Click OK to permanently flatten transparency in the file. 5. You are asked to provide a name and location for the new file. Note: When you click OK in the PDF Optimizer dialog box, PDF Optimizer applies all the selected settings in all panels, whether you have recently applied them or not. To prevent accidental changes, review the settings in the PDF Optimizer panels before clicking OK. For more information on PDF Optimizer settings, see "Using PDF Optimizer to optimize files for print" in this chapter. Optimizing file size You can optimize files several ways, including by reducing their file size. You may be able to reduce the file size of a PDF file simply by using the Save As command. This command rewrites the file, removes duplicated or unnecessary information, and does not require you to regenerate the PDF file from the source file. Adobe Creative Suite 4 Printing Guide 123
