I have been trying my hand at some basic printmaking techniques again. This is a paper plate lithograph, also known as xerox lithography. It is a fairly simple technique and is pretty low in toxicity - you use a xerox or toner copy as your plate and gum arabic to repel the ink. Amazingly, you can use "the plate" two or three times. I can see a lot of potential with the technique as a method of working with my photos as an alternative to inkjet transfers. As you can see, it's a very different look.
As a complete novice in the area of printmaking, I would really appreciate some advice about refining this print. I have uploaded a detail shot of this print and am wondering if someone can tell me what I am doing that is causing the patches of ink. Is this a problem with the application of the ink or is the problem in the way I am doing the transfer? (I used a baren). Or perhaps it's something else? Any tips would be gratefully accepted.
