A quick and easy introduction to the process of collographs is to have the students complete glue prints, like a relief. All you need is some scrap cardboard, white glue in bottles with a fine tip, printing ink and a few brayers. Once the sketches were done, we transferred the image to the cardboard and the students "drew" their image again with glue and left to dry over night. I set up four different printing stations in the classroom and had the students complete a print on white paper and another on colored paper. Spectacular dragons were the results!
