Francesco Siqueiros founded El Nopal Press in 2004. The fine arts press prides itself in using the specialized technique of lithography, which repels ink everywhere except where it is supposed to be printed. It is a collaborative process that bounces ideas between Siqueiros and the artist he is working with. Interested in the works made by Chicano artists and being located in the heart of Downtown LA, Siqueiros never runs out of ideas. Siqueiros keeps the art of print-making alive because he believes that humans need physical experiences to satiate their senses.
