i am wary of this yudu thing. maybe it's because i learned to screen print using a traditional exposure unit, screens ect. i don't like the how you expose screens with those sheets and the ink costs to much (you can get a big thing of speedball for about the same price) and screens aren't that expensive (hint: cover your wood screen in duct tape - it keeps it from getting warped when you wash it out)
i dunno i think if your gonna get a home printing kit get a gocco!
I learned screen printing the traditional (and messy) way at school, and I personally think the Yudu thing is a waste of money. I saw it on TV at work one day and was kind of appalled at it. It made it seem like screen printing was some magical thing no one had ever heard of before... made me kind of angry, actually... but anyway.
Speedball makes a kit, complete with two screens, three inks (I think... maybe more), drawing fluid, fluid remover, emulsion mix, a squeegee, instructional booklet and DVD, and a printing board (has hinges that connect to your screen to keep it in the same place. Great for layered prints.), for about 100 bucks. The only thing missing is the exposure unit, which is super easy to make with a high watt light bulb and a pie tin.
Making your own screen frames, putting in fabric, and making your own exposure unit and printing board would cut the costs down even more.
But I guess the Yudu is just great for everyone who wants everything right there, right when they wanted it, or who aren't inclined to making their own screens/exposure unit/whatever.
I am kind of curious about these exposure sheets tho. It sounds a lot easier than spreading that green smelly goop all over the place.
