Stone Lithography - 2nd Etch

In this video we use Biodiesel to replace the traditional solvent wash-out procedure, followed by an asphaltum printing base. Remove the gum layer with clean water, wet-sponge then dry-sponge, and roll up in Graphic Chemical Shop Mix black. Once the image looks good, dry, rosin and talc, and apply etches. Buff! Buff! Buff!

That's an unusually nice litho stone, no breaks, imperfections, or hairline cracks. These days few people recognize the labor required and special qualities of stone lithography. I always tried to avoid using the old Fuchs&Lang press since the Brand press was so much better in every way.

Thank you for making this video

Hello, Really great video, all aspects of it, the images, the calmness, the clarity of the explanations, etc, etc. , thank-you. I wonder what you use for 'bio-fuel' ? is it Estisol? if so, where do you get? who would be the right supplier? I have been trying to get in touch with Sequens, who seem to manufacture it here in Canada, but I have not heard back from them. Thanks, Katah

Hi, Katah, thanks! In this video (and here at the U of R studio) we use "B100 Biodiesel". We used to get it from a small, local refinery, but several years ago that source dried up. So now we make our own, in-house. It's a pretty straightforward process. It has replaced all instances of Lithotene, Varsol, etc., in the Print studio. I even have the oil painting faculty and students using it instead of mineral spirits for cleaning brushes. If you want to send me an email [e-mail] I would be happy to send you the recipe and instructions. In terms of Estisol, we do use that as well, but only the "150" which is pretty strong, and it is used for things like the photo-transfer on the stone in this video. I have a good supply stashed away, so I am not sure where or how to get it in Canada at the moment. Good luck!

@@professortruszkowski sounds great, I'll get in touch with you via e-mail. Thanks a lot!........K

Where did you get your cellulose sponges?

[@professortruszkowski]

Amazon.ca unfortunately. They are getting harder and harder to find in a decent size or without a scrubby scratchy side.

Part 3 ?

Don't you wash out the image again? or do you just wet the stone and pick up all that gunk with your sponge? - what if you wanted to print it in pink? This is very different from the fast and messy way we do it at the museum (one etch and we are off printing with no asphaltum - never used any rosin either :D, it's just draw, etch, print. This however seems like a safer way to go when making stones for a fast press. We just got the one we have up and running) Anyways thank you for the videos, new things to try out, and maybe a better way of securing success :D

[@professortruszkowski]

The toner transfer doesn’t wash out, and in fact acts as a printing base. It won’t come up when printing, either. If you want to print in pink, you rub up with pink ink (instead of Asphaltum) during the washout procedure and carry on as usual >> wet the stone, and roll up in pink. The image transfer will grind off when you resurface the stone, but otherwise it’s pretty stable.

@@professortruszkowski Thank you for the in-depth answer :) - gonna try this method out tomorrow and see what result I get.

1 million coating before you see anything. Not for me.
