Judge took the parchment that he had put away and started writing on it with a fountain pen that he took from inside a secret compartment in his desk. The prerequisite for writing runes is that, unless it was written on a special paper, you have to use blood.
Judge had requested a fountain pen without any ink and filled it with his blood beforehand, it was when he was just starting to learn runes, he had read that it required blood in the book about runes his grandfather gave him.
He had first tried to create the fountain pen within the studio and bring it back, but alas, he could only create stuff and bring it to the outside world before was because it was all just an illusion. The fake reality had registered it as an attempt to teleport stuff and created it within the illusory world.
