You can transfer any text and artwork to stamp making vellum by using a photocopier, however to get the best results and to make efficient use of material a computer and graphics program is the prefered method. It is best to use a program that works with both Vector (line art) and Bitmap (pixels) images. The industry standard is Coreldraw and is relatively easy to use. Programs such as Microsoft Publisher work well if you are happy to limit your designs to bitmap images without having the editing features the programs like CorelDraw have.
