Generative artwork, analog print
In this approach, I write a computer program that produces images, and I use a mechanical plotter to transfer the drawing to a paper. The plotter does not have ink of its own, like a printer, and instead it relies on a pen or pencil - in fact, anything that can draw, it could be also a brush. I call the artworks made with the mechanical plotter analog prints.
I use several media for analog prints, and they are all acid free and guaranteed to last for generations. The most common being:
Cotton rag or 'cotton rag paper' Cotton paper is superior in strength and durability, with some being certified to last for hundreds of years. High-end papers for watercolour can also be made of cotton. I use for example ARCHES Aquarelle paper in some of my prints. Rags can be also used in fine art digital prints, see.
Black paper, acid free I use black paper for my artworks with white or metallic pigments. See for example Untitled, Boxes.
