Thanks for the comments, glad you like our stuff! I just found that you were asking about “green” letterpress. We also offer this at our press. We use soy inks, paper with high PCW/windpower etc. But we also print with traditional inks – oil based inks. Honestly there isn’t a huge difference printing with soy vs. oil. They both are ink. Oh and another thing, is when you get rid of your rags after clean up, have a service do it or drop it off at one, they can dispose of them properly or have them cleaned and recycled.If you are interested in soy inks, check out the place we order it from….http://www.gansink.com. They also have some great info on their site. Also, Mohawk Paper has great info on their site and you can now order from them in smaller quantities, http://www.mohawkpaperstore.com/.Hope this helps! – toni, praxiumpress.com
