You ink those lines and run it through a press. The paper has to be soaked beforehand because the ink is just in the grooves. The press forces the paper down into the grooves and creates a print. The paper has to be long enough on each side so that when you run it through the first time it can stay stuck in the press while you put the next plate in place. It has to be in exactly the right spot.
Printmaking requires a lot of registration to make sure everything is going to match up.
Right now Christensen has been doing a lot of intaglio, but he wants to get into doing more Lithography in the future. It helps me feel more involved. I like the feeling that I have to actually do some physical work in order to obtain the final result . . . Christensen has done enough printmaking that he has learned to let accidents happen where he wants them to and in a way that will usually make them work for him. Sometimes things do not go how he plans.
