9 reasons to preflight

This content was developed by VIGC

Preflight has been around for many years and has proven its value. However not everybody preflights. Some printers still go into production after a manual check, or worse, not checking the files at all. The number of content creators that don’t check files before sending them to a printer is even higher.

Preflighting your files can save you a lot of money as many errors can only be detected by preflight software. And those errors do create trouble afterwards!

The poster you can download here shows you why you need to preflight. It sums up nine of the most common errors that are detected by GWG compliant preflight applications.

Open this test file in a recent version of Adobe Acrobat or Adobe Reader®. Do you see any errors that will cause a problem in print? Now send this file to your proofer or your RIP.

Please note: an ordinary desktop printer is not a proofing device! Files are handled differently and can come out wrong. If you have another PDF viewer on your system, other than Acrobat or Reader (e.g. Foxit Reader,or Mac OS X Preview), use that one too and check if both viewers show the same content.

Now check the file with the GWG compliant preflight application of your choice and with for instance a ‘sheetfed offset CMYK’ profile (you can download it from the GWG website if not already available in your preflight application). You’ll see why you need preflight, why you need the GWG!
