Continuing the process of spit-biting photopolymer plates. This time, adding pigment to the mix!
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
A homemade timer switch prevents over-etching due to forgetfulness.
