This may surprise you, but many outdoor signs that are sold on the internet are digitally printed. Look carefully at what they say about outdoor longevity. One of the biggest sellers admits "5 years". If you only need a sign to last 5 years, buy digital. They look beautiful for a few years, and they're less expensive because they can be made quickly and shipped out within 24 hours. But if you want a permanent outdoor sign, buy from us.We solvent screen print our metal signs and bake them at 400 degrees. WHY SOLVENT SCREEN PRINTING IS BEST
