Trying something new. Or at least different....

Let's just say it: I am in a rut. And I have been for quite a while. I'm not excited about any of the ideas I have for linocuts... they all just seem to be variations on a theme. I'm flailing around, looking for an interesting spark.

Which is why I took a complete detour a few weeks ago and finally made a little TetraPak printing experiment. A what printing, you might ask? It's an intaglio process, like etching... but not nearly so involved as working on zinc or copper with all sorts of questionable materials, because the printing plate is a piece of TetraPak. You might know it as a soup box.

Talk about a low-tech plate!

Unless you've cut open your broth box and peered into its depths, however, you might not have realized that the inside is coated with a thin layer of foil. And that foil can be scratched with a needle, as one does when making a drypoint etching. The foil is, of course, squishier than a zinc or copper or acrylic plate, but if you're not worried about precision, it's good enough!

It's probably been... ooph... 40 years (what!?!?) since I've inked and printed an intaglio plate. Unlike relief printing, which involves rolling ink on to the surface of the plate, intaglio printing requires pushing ink down into the incised lines and then wiping off the surface. A damp sheet of paper will press down into the lines and pull up the impression. 

All of which means that I had forgotten what a mess it can be to ink and wipe an intaglio plate. I definitely need a better system. But here's the inked plate:

I never did get a consistent combination of inking, wiping, paper dampness, and pressure, but I did get a nice set of experiments.

Intaglio was my first printmaking love, although I learned to make etchings using zinc plates, aquatint rosin, nitric acid baths, asphaltum varnish, kerosene.... you get the idea. It wasn't a process I could maintain without a properly ventilated studio and the capacity to manage all those questionable chemicals. 

Some years ago (decades now, no doubt) there was a lot of excitement around the newish, less toxic process of solar plate etching. I never had an opportunity to learn how to make solar plates, although what little I knew seemed a step removed from the immediacy of drawing a needle across a treated plate to create an image. 

Using TetraPak felt a little more my "style," but I definitely need more practice to achieve any sort of consistency. And the "squishiness" of the foil doesn't seem to give me the control I'd like for making marks. Still, it was nice to take an afternoon to just play around... something I don't give myself nearly enough time for.

  1. I work with real-plant hand coloured collagraphs. There is no way I can get my inking & wiping & hand colouring the same, so I make EV = edition variable - editions, and I love them. Each is an original. Now your skill with reduction linocuts is just awesome, so I suspect you could build up the skill to get an identical tetra-pac edition, but consider enjoying the process, and loving your variable beginnings. My limited experience with tetra-pac prints is that the bur from the drawing degrades quicky, so the the prints change, in any case, and edition sizes are small.

    1. Yes, thank you, Jacky! It was fun just to mess around with the process and not have expectations. I need to do more of that! I also tried to do the aluminum foil/cola lithography... but that was a disaster. I don't know what I was doing wrong, but it didn't work. An adventure to try again another day!

  2. Etching aluminium using coper sulphate works for me. The copper sulphate and table salt solution is safe to handle and the aluminium is a grainy metal which means it bites without needing a resin aquatics. Means I can etch in the spare room.

    1. Ooh! I will have to look this up. It's been decades since I've tried to work with metal plates of any kind, so I'm not at all up to speed with what's possible. Thanks for the tip!

Linocut in Progress: Did You See That?

Put on your deerstalkers and get out your magnifying glasses, because we're back to trying to sleuth out the order of operations on this...
