What you want to do is not going to work. I'm not sure about the 2 part urethane and it's adhesion to digital prints. In fact I talked to the court manufacturer and he said he'd never heard of a 2 part urethane for sport courts. Anyway, the adhesion of the urethane to the print is not the issue. The problem comes from the adhesion of the print to the floor. It is just not strong enough to hold up for any length of time. Trust me, we've tested it thoroughly and it won't hold up for even a year. The players pivoting on the graphic will make the vinyl adhesive fail, usually within months. Then the urethane top coat will crack and the whole thing will start peeling away. For temporary graphics, like what they use on the Final Four courts, (the company I deal with has made the NCAA Final Four courts for the past 2 years) they simply put a laminated graphic on top of the court and replace it when it gets damaged.
For permanent graphics you have to use paint and then urethane over the paint. We mostly use Poloplaz game floor paint which is a urethane paint formulated much like a primer for urethane. But One Shot with hardner will also work. I had to paint a metalic gold on the Boston Celtics court. Poloplaz does not make metalics so we used One Shot with the maximum recommended amount of hardner and it is holding up just fine. Much testing is done for adhesion qualities for Poloplaz paint tomake sure it will hold up with all the expansion and contraction, flexing, and players pivoting on the wood.
I know this is not what you wanted to hear, but it is what it is.
