This is common due to transfer tape taking an aggressive hold on the vinyl material when rolled up for shipping. 99% of the time if you lay the print flat prior to installation for a few hours it will relax the print, tape, and liner. It will still have visible wrinkles or tunneling, but you can be assured that when you install you will find that once the liner has been removed, the transfer tape and vinyl will be at ease and ready to install without the wrinkles or buckling.
