For outdoor applications we recommend trying samples of our weatherproof materials which are very durable and water resistant. However, the ink and toner used in standard inkjet and laser printers is not likely to be UV resistant. Exposure to direct sunlight for an extended period of time could cause the colors to fade. For best results, adjust the material type setting in your printer options to a Labels, Photo, or Glossy setting. You may also want to consider a UV resistant spray which can help minimize fading. You can view the available weatherproof materials at the link below. https://www.onlinelabels.com/weatherproof-labels.htm You are also welcome to request samples of these materials by visiting the following link or by contacting our Customer Support Team at 888-575-2235. https://www.onlinelabels.com/samples
