Safer printmaking for artists
Many metal plates have a protective coating including zinc and aluminium. You have to give them a scrub, then a light polish to take out any scratches and degrease them well before applying the ground. Always a good idea to do a test stript in the etch first to see how aggressive the solution is and adjust your timing accordingly. Sandra
I usually use different grades of sandpaper to prepare my aluminium and zinc plates with moving from coarse to finer grades. So I am looking to find out if are there hybrid metals that might resist etching and if so do I need to be clearer about the zinc I order and from what type of company. Thankyou for replying to my query. Gina
Thankyou Sandra, that would be greatly appreciated as I have not been able to get a straight answer as the merchants I have spoken with have little idea of what I am hoping to do.
Hi Gina, I thinking that you resolved this some time ago? But ... I had a problem when I bought 'zinc' once and I think my problem was that it turned out to be a composite metal. Roofing Zinc I bought (from Booths in Sydney?) many years ago has always been fine. See you soon, Amanda
Thanks for your reply and input. It is good to know that other people have experienced a similar hiccup when finding the right metal to etch. It reminds me that even very recently a very seasoned printmaker could not get her aluminium to etch and that was after sanding the metal with an electric sander. She wondered if she had gone too far down into the metal so to speak. See you soon too,
