W/G/B is one of Marco Breuer's first explorations of the traditional medium of printmaking. Traditional in the sense that the artist had in the past explored many ways of mechanical image-making, some of them very similar to printmaking techniques, but he had not specifically attempted to create a conventional edition within the confines of any particular print medium. In fact, he still has not, since W/G/B found the artist creating groups of images (some of them etched, some screened, some relief-printed) and then arranged in sets of three, each different that the others. Each print was made using a variety of printmaking and/or mark-making techniques, from intaglio, relief printing, screenprinting and monoprinting to scoring, hole-punching, hammering, pin-pricking and folding, or a combination of each. W/G/B (the title referring to a shortened photographic grey scale) further explores Breuer's themes of time, repetition, process, materiality, and evidence of physical activity. The imagery ranges from simple to complex, and the results, although black and white, show quite a range of 'color' in their grays. The grey scale is referenced by the fact that the first sheet in each triptych was printed on white Fabriano paper, the second on Magnani Grey and the third on Arches Cover Black. Breuer has been primarily engaged with photographic papers as his medium of choice in the past, exploring the many ways the paper and emulsions could be manipulated to create the marks and colors he was looking for. With the medium of printmaking, the artist found the process as equally restraining as that of photography, if not more. The inks, presses and repetitive nature of the process were a very specific challenge, and not particularly interesting in their rigidity. In the end Breuer imposed not only one but two structures of his own on the project: The 'photographic' triptych format, and the non-repetitive freedom that monoprinting gave him to create this edition.
