Continuing the process of spit-biting photopolymer plates. This time, adding pigment to the mix!
Or, how I learned to rethink my materials, again.This post follows on the heels of the last ("Blocking Light In a Creative Way"), and recounts another scenario where I made a major inroad in how I approach media, process, and critical thinking. One of the major themes in my studio practice is adaptation. Besides narrowing … Continue reading Spit-Biting and Photopolymer
Or how I learned to rethink my materials...
The electrolyte is the solution that allows electricity to flow from one plate to the other. There is a different electrolyte for different metals. For copper, the electrolyte is copper sulfate. For zinc, the electrolyte is zinc sulfate. For steel, the electrolyte is ferrous sulfate. All three chemicals are readily available online; copper sulfate is … Continue reading The Electrolytic Solution
Here are a few more little photopolymer intaglio prints with a lot of tinkering on the part of the transparencies. No digital bits here! I've been really interested in capturing physical forces, much like early scientists during the advent of photography. These images are a result of capillary action, a physical phenomenon that allows liquid … Continue reading Some New Little Experiments
Check out the equipment section for a blurb about how I adapted the traditional method of spitbiting to electro etching.
By plating your lines instead of etching them, you create a burr similar to those of a drypoint. This is the very first pull. I'll probably try to ink and wipe it differently next time.
Relief etching can do some wonderful things to the edges of a plate, but how do you print it with those rough/sharp edges? I made a kind of jig from the fall-out of a matboard opening. These already have a 45˚ angle on the edges, which mimic the beveled edges of an etching plate, and … Continue reading Printing Relief Etchings
Besides time, you can affect an etch through the strength of the current flowing through the circuit. The lower the amperage, the more delicate the etch, and the finer the details. Conversely, the higher the amperage, the stronger the etch, the courser the details. Amperage, voltage and ohms are often described using an analogy to … Continue reading Virtue No. 463 – Adjustable Strength
