ive been keen to try out some of these glossy white blanks but they are incredibly expensive when you can get a 50 spindle of the matte white variety for about 17$au. will be intrested in the spray tutorial as a solution for all the stuff ive already printed.
no one has mentioned this LightScribe technology yet. you actually burn your disc...then flip it over and the laser burns images into the other side. no color of course and its new and requires special media so expensive i assume. intresting idea though.
