What I see when I open a file in Adobe Acrobat isn't always what I get when I print it. What causes this to happen?

While PDF files are, generally speaking, a WYSIWYG format, there are many situations in prepress that can cause inconsistent output. The key is to make sure that Adobe Acrobat is set up to properly preview the output. When work is created in InDesign or Illustrator, elements in the design can be set to overprint. Acrobat DC, by default, does not display these overprinting objects properly. To set Adobe Acrobat DC (or even the free Adobe Reader application) to preview objects that overprint accurately, go to Adobe Acrobat DC > Preferences > Page Display. Under the Page Content and Information section, set Use Overprint Preview to Always. Moving forward, any objects that contain overprint attributes will now be displayed properly.
