I dont think 99% of our customers know the difference between a print, and cut vinyl.
I'm not sure on the long lasting part either. Technology has come a long ways... I have some prints / wraps out there that have been out for 8+ years on a police vehicle, and it looks almost exactly the same as a new wrap we did. Will a non printed vinyl last longer? Sure... but will a wrap or sign outlast how long the ink does? The 8 years is probably the oldest sample we have because their vehicles dont stay in the fleet for that long.... but its the only thing we have a side by side comparison for.
We have a wrap by our shop that we did when we moved in 12 years ago... Full print wrap, it looks perfect to this day. Of course I cant do a side by side to see if its faded... but it looks just as vibrant as the day it was installed.... I can see it getting another decade before it gets replaced.
That said... I'm aware BC doesnt get as much sun as say, Texas - And I'm sure it makes a much bigger difference there. But a good vinyl / overlam with a print should still last a decent time... so I dont see the need to tell the customer! At least not in our area.
But yes... it costs us more to produce a color than it does to bring it in. But then you only need to bring in white, and not 10 yards of 50 different vinyls... so win win?
