Herbert Aach's "Split Infinity #8BS" is a screenprint that exemplifies the artist's exploration of geometric abstraction and optical phenomena through the medium's bold, flat color fields. Created during Aach's prolific period of investigating visual perception and mathematical principles, the work employs precisely divided compositional elements that create a sense of dynamic tension and visual movement. The screenprint technique allows Aach to achieve the crisp edges and vibrant color interactions characteristic of his investigations into how viewers perceive spatial relationships and color relationships simultaneously.
