Everything you need to know about Sign & Display


Sign & Display is an incredibly varied market, that is home to many widely different products. It ranges from photo-print, over hanging or roll-up banners, car and bus wraps to huge billboards. To capture this variety, the GWG developed a sign & display specification around two key variables:

  • Average viewing distance, which is defined as the average distance that will exist between people looking at the printed job and the job itself. This could be as little as half a meter for a photo-print or as much as 50 meters for a highway billboard.
  • Scaling factor, which is how many times the job as delivered to the printer has to be enlarged before being printed. This is because in many sign & display workflows, print jobs are delivered scaled down by a factor of 2, 10…

Note that the Sign & Display specification does not cover small format digital print, the Ghent Workgroup has developed separate guidelines for this segment.

Not sure your workflow or RIP are up-to-spec?


Receiving good PDF files is an important point, but your workflow and RIP need to be able to handle those files correctly as well.

Not sure they will? The Ghent Workgroup developed its Ghent Output Suite specifically to test for this.
