Printing marker for calibration?

I wanted to run through the calibration process but I’m stuck at step one – printing out a marker that the depth camera can see. I have tried blocking the laser in various ways, but it seems to be an issue with the ink used in printing – either the IR camera sees a completely white sheet of paper or nothing at all. I’ve been talking to some print shops about this but no one’s offered any solutions for it. Is there a specific type of ink that needs to be used when printing the marker?

Did you try to use IR reflective stickers in a black non reflective background?
