When trying to produce a photoresist stencil, begin by creating the image you wish to re-create. Often, simple clipart is being used, which you can find online or purchase from a collection. For both sources, it is important to point out the issue of copyright — just because a design is online, or you bought a collection of artwork, does not mean that you have the right to use it. Please read the fine print for bought collections. When online, you will be informed right away as to what you need to do in order to use a design.
