He tried everything. He took many illustration classes even though his emphasis was drawing and painting. Since his bachelor's degree was an art composite with emphasis on drawing and painting he stayed around Cedar City for another year to build up a printmaking portfolio for graduate school. He was not taking classes but the teacher let him use the studio, allowing him access to everything he needed. The basics To understand why Christensen loves printmaking, you have to get the basic idea of what it is.
Printmaking encompasses many art disciplines and there are different types of printmaking.
Two that Christensen uses are lithography and intaglio. With lithography you draw with grease crayons on a large piece of limestone. Since water and grease do not mix, where you draw will later attract the ink, and due to other processes the remaining area won't attract ink. To do intaglio you use a zinc or copper metal plate that you etch with acid. You put a protective covering called hard ground on the surface and then scratch through that to expose parts of your plate.
