Well, I guess I stand corrected on several counts. I really thought someone layering would be using cast die cut........ and someone doing two colors on air egress would be using digital printing methods. Never would I think you used two layers of air egress. It still doesn't look anywhere close to 150 sq ft. However, that's up to you how you waste material.
Also, if I give a time frame, that's based on me..... my time or one of our employees. Employee's don't f*ck off, huh ?? Lol
We do quite a bit of some nice sized tri-axles from front to back and our graphics are almost 48" tall at many spots, with stuff all over the place and on the rear. We layer it on, also. We probably might get close 200 sq ft. When we do print..... it's 1/2 that.
If your caps are 12", the other stuff looks to be about 8" or so, with the other stuff around 4".
Anyway, you should probably think about printing that stuff, instead, especially if you're using digital materials.
