Heemin Chung manipulates digital images sourced from the web, printing or transferring them onto acrylic medium to create multiple layers, which she then overlaps onto the canvas using various methods, thereby materializing the textures of digital images. This process begins with collecting images of flowers, landscapes, and other elements from the web, which she processes and recomposes using digital tools like Photoshop to create what she calls a 'sketch' of the work. However, from my perspective, this 'sketch' is closer to a 'design.' This is because Chung's works are not merely two-dimensional planes but rather 'non-flat' structures composed of intricately arranged layers. This 'sketch' must contain all the elements: the shapes and colors that will be painted onto the primary support, the canvas, as well as the composition of the acrylic medium that will be folded and layered over it in various ways. Naturally, the sketch itself is a multi-layered digital image. Following this sketch, the artist paints the forms onto the canvas and, using it as a guide, layers and folds multiple acrylic layers over the surface.

Some of the acrylic medium that covers the canvas is printed with digital images composed on a computer using a UV printer. Other layers are created through inkjet print transfers. Chung utilizes acrylic medium without adding pigment, modeling it into forms and then applying images onto it, or transferring pigments onto its surface during the drying process to create thin layers. To achieve this, she spreads the medium onto a flat support and waits until it dries—several hours in winter, or several days in the humid summer—before carefully peeling it off like a skin. The detached layers are then folded or bundled in various ways before being attached to the painted canvas.

Chung’s distinctive working method, which combines digital image manipulation and printing with painting on canvas and a kind of collage that incorporates objects onto the canvas, has so far been primarily discussed in terms of the "coexistence of the immateriality of digital images and the materiality of painting" (Hongki Kim) or "the dialectic between digital and painting" (Jung-hyun Kim). However, I believe it is time to shift this perspective. Given that most of our daily lives are already integrated into digital networks and that almost all images we encounter are digitized, it is no longer convincing to speak of digital images as 'immaterial.' Furthermore, anyone familiar with contemporary painting knows that nearly all paintings today are directly or indirectly dependent on digital images. Digital technology is no longer an opposing category to traditional media such as painting, sculpture, ceramics, or textile art; instead, it functions as the backdrop for almost all artistic activities today. Approaching Chung’s work through the framework of "digital vs. painting" fails to illuminate its individuality.

I propose the concept of "non-flat." The term 'non-flat' is derived from 'flat,' a word that denotes being level, smooth, or without curvature. Notably, the term 'flatness' has had an illustrious career in the history of Western art, thanks to modernist art critic Clement Greenberg. According to Greenberg, painting must actively embrace "the ineluctable flatness of the support,"1 as it is "unique and exclusive to painting as an art form, distinguishing it from literature, theater, sculpture, music, and other arts."2 The concept of 'non-flat' rejects Greenberg’s premise that flatness is uniquely intrinsic to painting. However, it does not seek to revive the 'sculptural illusion' or 'fictive depth' that Greenberg opposed to flatness. Instead, 'non-flat' aims to remove 'illusion' from 'sculptural illusion' and 'fictive' from 'fictive depth.' 'Non-flat' is not 'counter-flat.' Rather than seeking to overcome flatness through opposition, it operates in the space between flatness and its negation. It aspires to surpass flatness while still relying on it, transcending flatness without completely abandoning it. Existing in the tension between flat and counter-flat, 'non-flat' strives to move beyond the flat plane while remaining within its constraints.

The issue of 'non-flat' has been present in Chung’s work from the outset. In her 2018 exhibition, UTC –7:00 JUN 3PM On the Table, she used the 3D modeling software SketchUp to create 3D images of objects like fruits, knives, straws, and teddy bears, which she then painted onto canvas, layering thick acrylic medium and oil paint over them. The illusory spatial depth conveyed by the 3D images paradoxically contrasts with the illusory flatness of the actual clumps of medium on the canvas, creating an intriguing tension. This tension of 'non-flat' is fully realized in the new working method that emerged from Serpentine Twerk, featured in the 2021 exhibition How I Learned to Stop Worrying and Love the Bomb, and continued through her 2023 solo exhibition 《Receivers》. Here, she explores ways to transcend the flat plane through the plane itself by folding, layering, and stacking acrylic medium. Typically, acrylic is used to create flat images on a canvas, but Chung employs it as a material for surpassing flatness. She applies the acrylic medium onto a flat support, allows it to dry, then peels it off, suspends it, binds it, folds it, or tears it before attaching it to the canvas. These multiple layers of thin, flat acrylic, stacked and folded like a shell or skin, do not constitute mere illusion or virtuality but instead create actual undulations—yet they remain distinct from sculpture. Because they are still attached to the first-level support, the canvas, their outlines retain their planar quality.

This tension inherent in 'non-flat' is most strikingly expressed in Plain of the Survivors, featured in 《Receivers》. Chung sourced a 3D image of a severed tree stump from the web and used SketchUp to generate its inverse image. She then 3D-printed this inverted model to serve as a mold, which would typically be filled with medium to create a cast. However, instead of filling the mold, she spread FRP (fiber-reinforced plastic) onto the inner surface, creating a thin layer, which she then peeled off and turned into an artwork. Although the folded FRP layer occupies space like a sculpture, upon closer inspection, it functions similarly to the acrylic medium in her other works—folded layers of a plane that generate a 'non-flat' form. Whereas the acrylic medium, folded and layered onto the canvas, evokes a melancholic sense of beautiful ruins, the 'non-flat' FRP forms that detach from the canvas and lie like discarded shells on the gallery floor reinforce a sense of material dissolution—the loss of solidity, the gradual disappearance of matter over time.
