Viewing your PDF

We strongly recommend using Adobe Acrobat Reader/Professional to view your PDF. It is Free to download for PC and Mac users. It is also available for free on mobile platforms.

There are some changes we recommend to the default settings in Adobe Acrobat Reader/Professional that will assist you in the viewing of your PDF file.

Open Adobe Acrobat Reader/Professional and go to the PREFERENCES option. (Mac users go to ACROBAT>PREFERENCES. PC users go to EDIT>PREFERENCES.

page display

Select PAGE DISPLAY on the left (above) and under PAGE CONTENT AND INFORMATION (below) tick the option for SHOW ART,TRIM & BLEED BOXES. This will put boxes over the artwork indicating the trim and bleed areas. This will make it easier to identify your images are bleeding properly when viewing the PDF.

We also recommend setting USE OVERPRINT PREVIEW to ALWAYS. This will indicate any overprint issues such as white elements being accidentally set to overprint in InDesign which would in turn make the white disappear on the final product.

Overprint

Please check the rest of the PDF for contents and if any RGB images were used, check that you’re happy with the CMYK conversion.
