The Clear Gloss Inkjet (CK) is unfortunately not considered a weatherproof material. For inkjet printers, you would need either the Weatherproof Gloss Inkjet (WI) or Weatherproof Matte Inkjet (WJ) materials. We're happy to provide free samples of these materials if you'd like to test. You can request samples at the link below: https://www.onlinelabels.com/samples
