However, the traditional photogravure process is notoriously demanding. It involves toxic chemicals (dichromates, acids), heavy copper or zinc plates, carbon tissue, aquatint dust (or its industrial equivalent), and a lethal level of precision. As environmental regulations tighten and studio safety becomes paramount, many contemporary printmakers and photographers are seeking a "photogravure alternative."
The original Woodburytype (1870s) produced continuous-tone images in a lead mold. Today, you can replicate this using polyurethane resin and a photopolymer relief plate . You expose a polymer plate, wash it out, then use it as a mold to cast polyurethane. The resulting cast has a 3D surface topography exactly matching your image’s tones. When inked relief style (on the raised surfaces) and printed, it produces a continuous-tone image that rivals gravure. photograv alternative
You prepare a metal plate with a conductive ground (e.g., a hard ground or a photoresist). You then place the plate in an electrolytic bath (usually a saltwater or copper sulfate solution) with a DC power supply. The plate acts as the anode. Electrical current dissolves the metal where it is exposed. Today, you can replicate this using polyurethane resin
While traditional gravure has a soft, painterly edge, polymer intaglio has a sharper, more photographic edge. To mimic the soft halation of gravure, artists use diffusion filters during exposure or slightly defocus the UV light source. Part IV: The Hybrid Electroetch (EDM for Printmakers) For those who crave the permanence and feel of a true metal plate (copper or zinc) but recoil from ferric chloride or nitric acid, electrolytic etching (electroetch) is the answer. When inked relief style (on the raised surfaces)
