Re: Questions about etching aluminum and copper plates

I've experimented with different types of inks as resist at the time with varying results. Apparently the type of ink had little impact and my biggest problem was the resist not adhering well to the plate sometimes. I like to work with very thin resists and sometimes parts of the resist come off the plate during etching. I noticed that this is significantly affected by the condition of the aluminum plate surface.

Are there any surface preparation techniques or special treatments recommended before applying resist to the plate?

Re: Questions about etching aluminum and copper plates

I never had good luck with acrylic inks as a resist using the copper sulfate mordant ... it always seemed to lift, no matter how well I cleaned the plate. I have used standard oil base inks with added cobalt drier. Paint the plate and leave it overnight to "dry". The only problem with oil based inks is removal ... try acetone or TSP if the paint has not been dried for too long. Do not use products containing lye, as that will etch aluminum. I generally do not do really fine line etching ... my favorite resist is ordinary shellac. Apply an even coat, let dry for 15 minutes, and you are good to go. It removes easily with d-limonene based cleaners ... i.e. citrus cleaners.

Cheers ...... Charles
