Chapter 31. Exporting, Saving, and Print... > Transparency Flattening - Pg. 736

Exporting, Saving, and Printing with InDesign 736 Transparency Flattening When you use any type of transparency in a document, including feathering, drop shadows, or an effect applied through the Transparency palette, the document has to be flattened to be printed or exported. The flattening process takes the area where transparency has been applied and breaks it up into individual vector or raster areas. You can set up transparency flattening presets to specify how this should take place. Note If you export a PDF to Acrobat 5 or higher, the transparency effects do not have to be flattened. Select Edit, Transparency Flattener Presets. InDesign comes preloaded with low-, medium and high-resolution flatteners. Select each one and read the description in the Preset Settings window to see how the flattener will affect your document. If you saved a flattener preset, or someone has provided you with one, click the Load button, browse to its location and click Open. Select any preset and click the Edit button to change any settings. To create your own preset, click the New button. Name your preset (see Figure 31.10). The options that you set in this dialog are as follows: · Raster/Vector Balance:Determine to what point artwork is rasterized. Rasterization converts vector graphics, or those created with curves and lines, to dots. The higher the setting, the less the graphics will be rasterized. This means your page objects are smoother, but they take longer to load and print.
