The Yudu is really simple - a tidy and compact exposure unit and print table.
You don't have to buy YUDU supplies; you can use any photosensitive screens/ films. Provocraft, who makes YUDU, also makes a small size screen about 5 x 8 or you can make them yourself if you're handy.
We use emulsion sheets from ULANO and SAATI print to simplify emulsion application onto the screens.
Are there silk screen machines for home use; perhaps available at big (or small) hobby stores? Like to use with small pieces of plastic and the like?
Are they difficult to use?
