Collagraphs are plates (or matrixes) made from collages. I usually use material that I find from the Andalucian or Finnish nature. The work is quite abstract but with a little imagination you can see many things in them.
After the collage has been made it gets a couple of coats of varnish and then it can be inked. Then a paper is put on top and it goes through the printing press. Due to the delicate materials used I can normally get max. 10 impressions out of one matrix.
