Wall Panels

What material is it?

 

A good practice would be to alternate your panel prints. i.e. rotate every other print 180°

 

Could be a number of things. Was it lined up all the way down? Meaning, you can take your ruler or measuring tape and there's a consistent 1/2" bleed overhanging the edge the entire length of 10' panel?

 

It's been a long time since I've seamed a graphic and never anything this big but when all we had was a Roland SP-300 I used to tape all of the panels onto the substrate at once and line them up. I would then vertically stagger the hinge tapes so to not interfere with the application of the panels before/behind it. Then I would apply the "top" halves of each panel, then go back and do the bottom halves. It was a huge PITA and I don't know if I could have managed it doing 10' panels. The largest vertical installation I ever did like that was maybe 5 feet, but my seams always matched up quite well.

 

What printer?

 

Have you got omas turned off?

 

In the media advanced options on the printer. Turn it off and see if the lengths are more consistent.
