Using one A4 sized plate, they made multiple prints with different inks on the same piece of paper. Here's how it worked: after making a drawing of an activity that they were looking forward to doing over the summer holidays, students then traced some-but not all-of the elements in their drawing. They over-layed the tracing paper on their styrofoam plate, traced the image again, and in that way, incised the plate with the drawing. The plate was then inked with gold ink and then printed.
After washing and drying the plate, they traced the remaining elements in their drawing and incised the plate again. The second inking was done with an ink color of their choice and they made their second print on top of the first print, being careful to line up the edges of the plate. The effect is really neat and the students loved the results!
