Adobe Reader software is the global standard for electronic document sharing. It is the only PDF file viewer that can open and interact with all PDF documents. Use Adobe Reader to view, search, digitally sign, verify, print, and collaborate on Adobe PDF files.
Don't forget to turn on OVERPRINT PREVIEW in your preferences for most printing and designing applications.
Here's how: In Adobe Reader or Adobe Acrobat Professional, select the application name from the menu, then Preferences. In Preferences, select Page Display. In Page Display, you'll find an option called Use Overprint Preview. We suggest setting this to "ALWAYS" from the start. The default is Only for PDF/X Files. Changing this setting will give you the truest represention of overprinting items and color saturations that would occur on press.
