    Hoping for some input on clear coating UV printed sign blanks for extra protection. Any problems or recommendations from others out there?

    I'm running an HP FB6100 with OEM inks which I have confidence will last 2-3 years printed as-is, but client was inquiring about extra protection and longevity. I've always had this nightmare vision of a clearcoat eventually eating away at the UV ink, bubbling up and falling off.

    Have a screen printer flood coat it (double hit) with a UV clear.

    I have a friend who owns a panel shop and when I have a job that I'm not sure of I just make some samples about 6" square and get him to lay a few coats of clear 2K the next time he's clearing coating a car (which is every day). I've been surprised at what fries under 2k and what doesn't.

    I clear coat most prints I prefer to clear over unlaminated prints. my clear is dc 2021 its a high solids clear and I always dust over the prints and ALWAYS clean them with water only and lightly scuff with worn out scotchbrite I MEAN LIGHTLY....after disting I put regular coat on it, I have no issues and the longest sign out is about5 years old now with no issues.

    I clearcoat over vinyl all the time and thses digital prints should be no different
