I printed 5 doors using 3m IJ35c for a company I laminated with Oraguard 210 gloss laminate. I installed about 4 months ago door was off the hinges door knobs were off so it was a super easy install no heat was needed graphic was plenty big so no stretching was used. I went back today to measure up some walls for graphics and I noticed the door vinyl has shrunk quiet a bit. I know that all vinyl shrinks over time but it has shrunk a 1/8" to possibly a small quarter inch. So my questions are: Is this normal? How do I stop this? Did I use the correct material for the job?
