First, print your document at the highest resolution you can print with your desktop printer. If the outlines are no longer there, you simply need to change a display setting in your Acrobat.
- Set Smoothing Preferences in Acrobat
Go to the Preferences in Acrobat and click on the Smoothing tab (or Display for Acrobat 5). Then uncheck the Smooth line art option.
- Set PDF Compatibility
If Step 1 doesn't work, or if the white outline shows when you print your job, then choose Acrobat 5 compatibility when you make your PDF (PDF 1.4).
If you are going to print this with an offset press, your printer's RIP should be Level 3 PostScript for the best results. Consult with your printer if you are unsure. As a guideline, if your printer can handle PDFs made directly from InDesign, without the use of Distiller, then he can probably handle Acrobat 5 compatible PDFs.
- Use Workarounds
If your printer cannot handle Acrobat 5 compatible files, then you need to use a couple of workarounds.
- The first one is to place your text on a separate layer on top of your graphics.
- The second one is to use clipping paths to get rid of background from your images, instead of using Photoshop's transparency.
