I brought my plate down to the electro- etching room and set up my plate so it would work correctly. I started by adding a rod to the back of the plate so that the clips could attach to the plate and allow it to actually work. Once the rod was taped in place I was able to attach the red positive clip to the top of the rod. I attached the black negative clip to a piece of copper that was placed in the water. It is similar to a battery where there need to be a full joined circuit for the process to work. The machine was set at 2 volts max so the max couldn’t go higher than that. I left my plate in for 15 mins to allow the water/zinc sulphate solution to eat away at the parts I’d etched out.
I was able to remove the ground off the plate using white spirits to reveal the final plate ready for inking.
