Using Photoshop for Rasterizing Intricate Artwork

If you are using Photoshop instead of Illustrator, you won't have a chance to select the objects you want rasterized; Photoshop immediately rasterizes everything you selected in Acrobat. One advantage of using Photoshop is that it won't try to substitute fonts, as Illustrator sometimes does.

After your selection is made in Acrobat, right-click inside the selection and click Edit Objects . . . . Photoshop will open and ask you for a resolution. Enter a resolution (e.g., 300 pixels per inch), click OK, and the rasterized results will appear. Inspect the results to make sure the artwork retained adequate detail. If you like the results, save the Photoshop file. By default, it should save as PDF, but sometimes you must change the Format to PDF in the Save dialog. Before saving the file, Photoshop will ask which encoding to use (ZIP or JPEG). If you choose JPEG, you can also set its quality level. After saving the rasterized artwork in Photoshop, Acrobat will automatically update the PDF to reflect your changes. If you still like them, save the PDF in Acrobat. Otherwise, discard them by pressing Ctrl-Z (Edit>Undo) or by closing the PDF in Acrobat and starting over.
