Photograv Alternative -
You print your digital image as a film positive (on a transparency). You then place the positive directly onto the polymer plate inside a vacuum exposure unit. After exposure, you wash the plate out. That’s it. No darkroom, no enlarger, no film intermediate (if you print a digital positive).
Instead of sensitizing gelatin with dichromate and exposing it through a film positive onto a copper plate, you expose a pre-sensitized, light-hardening polymer layer on a steel or aluminum backing. The unexposed areas are washed away with warm water, leaving a relief of hardened polymer. The plate is then inked and wiped exactly like a copper gravure plate. photograv 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. You print your digital image as a film
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. That’s it
The alternatives listed above are not compromises; they are evolutions. A polymer photogravure is not "fake gravure"; it is gravure for the 21st century. An electroetched copper plate is not a shortcut; it is a smarter path.
Now go make your mark.
