Outdoor materials must resist UV, moisture, and temperature change. Indoor materials do not need that level of durability; using outdoor-grade indoors can be unnecessary cost.
Outdoor requirements
For exterior use, check the rating of the complete print system: base material, ink, adhesive and any laminate. Exposure, orientation and installation affect performance. A coating or the word vinyl alone does not establish an outdoor lifespan.
Indoor-only options
Many paper and foam-board products are intended for dry indoor displays. Vinyl comes in both indoor and outdoor grades, with or without additional laminate. Compare the specific product rather than treating all uncoated material as indoor-only.
Deciding factors
- Will it be in sun, rain, or temperature swings?
- Expected lifespan (weeks vs years)?
- Will it be handled or only viewed from a distance?
Common mistake
Using an indoor material outdoors to save money. Replacement and rework usually erase the savings. Specify the environment and let the printer recommend the right grade.
