Charles Arnoldi's String Theory II combines polymer gravure, etching, and photo etching techniques to create a complex layered composition printed on Somerset paper in 2016. The multiple printing processes work in concert to build rich textures and varied tonalities throughout the work. The title references theoretical physics concepts, suggesting connections between abstraction and scientific inquiry. The intricate interweaving of lines creates a sense of movement and visual depth. This work demonstrates Arnoldi's sophisticated approach to contemporary printmaking.
