Every step of the process is done here at Anytime Sign, artwork, screen printing, and die cutting. We use the best quality materials and printing techniques: Solas3™ is approved by the U.S. Coast Guard as a retro reflective material used to enhance visibility of life saving equipment in nighttime, or low light conditions. Solas3™ reflects brightly when viewed with night vision equipment, providing crystal-clear friend or foe identification. The VELCRO® BRAND FASTENER we use has the highest quality acrylic-based adhesive glue and is able to withstand extremely hot climates. HOOK SIDE ON BACK OF PATCH ONLY, WE DO NOT PROVIDE THE LOOP SIDE. VELCRO® BRAND FASTENER 330 PSA 0172. Solvent Based Inks. All the inks we use on our patches are Solvent Based. Solvent based inks are better than digitally printed or UV inks because they adhere better and have a thicker ink deposit. Solvent based inks will not fade, even if they are left outdoors for years. Magic Black Infrared Ink. Magic Black is made and developed by Anytime Sign. We regulate the quality and the thickness for ultimate opacity in the visible spectrum. In the infrared spectrum, Magic Black becomes transparent allowing for the Solas3 TM to reflect light back to the Night Vision equipment, providing crystal- clear friend or foe identification.
