At-home Litho - Regraining an Aluminum Plate
HTML-код
- Опубликовано: 23 авг 2024
- In today's video, I attempt to regrain an ball-grained aluminum plate for lithography. I used 80 grit carborundum and my stones to grind away the surface.
Now that I have my own litho stones, you might wonder why I would need to do this. Wouldn't the stone themselves gives better results? Yes, I think so. However, my stones are all quite small, the largest being 10" x 20" (approximately 25 x 30cm). Aluminum plates could give me the option of working large-scale without fiddling with rolls of foil.
I'd say the experiment was moderately successful, the biggest challenge that I could no longer hold the warped plate down with water.
Thanks as always for watching!

Wish I could do this with aluminium roof flashing material. A really cheap source of plates!
I wonder if you could 🤔
It's really surprising what a cola etch can do. Maybe there is an way to grain it without causing the warping. Do you think it could possible to just flatten it again after the graining process?
This was my first time trying it and I will definitely try again. Maybe even sandwiching between boards, under weights after graining🤔 Or graining the reverse side a little to even it out.
What if you attached the plate to a substrate -- like masonite? As for regraining, I think I'd try a random orbital sander -- but I have no idea if this would be effective. Thank you for sharing this interesting experiment!
That’s probably a good idea for keeping it flat! Not sure about the sander.
@@valeriesyposz I agree....I doubt the sander would be effective, now that I've done a bit of research on the process.
If you want to do large size work find a metals store in your area and ask for a 1/16" or 1/8" aluminum sheet of whatever size you want. They'll cut to size and usually charge a multiple of today's market spot metals price x weight; example a 6"x10" piece would be $10 - $20, maybe a bit more depending on store and area. There's nothing special about these art sheets of aluminum, all aluminum sheet material is from one of 3 different grades of which one is affordable and the two others are mostly aerospace and expensive.
