Digitally printed Window Graphics can create a stunning effect when applied across large sections of window panels. In many cases the window panels will have aluminum mullions between them - and these mullions can ruin the effect of the graphic unless they are taken into consideration when setting up the artwork. We will explain why this is so important.
What are mullions?
Mullions are metal bars that separate window panels. The mullions can range in width but most commonly are 1” to 2” wide.
How are Window Graphics supplied for window panels that have mullions?
It is very common for large window panels to be separated by mullions. When Window Graphics are supplied for these window panels they will be printed, cut and supplied individually for each window panel. This allows the installer to apply one printed graphic to one window panel and achieve the best possible result. The alternative would be to supply one large Window Graphic to cover all window panels - but this creates too many difficulties for the installer and could cause much more installation time (and cost) and a poor quality job.
Can we just set up the artwork by splitting the image into the number of window panels?
No it is unfortunately not that easy. If the graphic image is just split into the number of window panels, the right hand side of one image will be the start of the left hand side of the next image. When the total window graphic is viewed, the graphic will not “flow” across the window panels correctly as the mullions will separate the image and create a gap in the image. Here is an example of how the window graphic would look if the image is simply split up into the number of window panels:
You can see that the image does not flow correctly across the windows.
How should the artwork be correctly set up?
The artwork needs to be set up so that the image that would cover the mullion is cut out completely. This will allow the image to correctly flow from one window panel to the next. Here is the same window graphic example that shows how it will look when the artwork has been set up correctly with the mullion width cut out:
