Are they like Rubber Stamps?

No, they are not rubber stamps - they are actually saved as image files, and then printed on paper right from your desktop printer. 

Sticker paper, vellum, tracing paper, photo paper, cardstock, whatever. If it can go through your printer it's workable

And as you see in the sample above commemorating Ohio's statehood, and the collaged bookmark and envelope at right, it's easy to enhance artistamps with rubber stamps, embossing powder & other craft supplies to create artsy, classic, vintage, or fun and funky looks.
