Bochner began making paintings in the late 1970s, and his paintings range from extremely colorful works containing words to works more clearly connected to the conceptual art he pioneered. For a 1998 work titled Event Horizon, for example, he arranged prestretched canvases of various sizes along a wall, each marked with a horizontal line and a number denoting its width in inches. Together, the lines appear to form a horizon, creating what Jeffrey Weiss in his catalog essay for Bochner's 2007 exhibit Event Horizon called a representation of "the world as a fantasy of quantifiable truth." Bochner made his first prints at Crown Point Press in the early 1970s, published by Parasol Press.
