What is Screenprinting? Screenprinting involves "pushing" ink through a screen over a stencil. It is also known as silkscreen, seriography, and serigraph.
Anatomy of Screenprinting Ink Squeegee Positive image on the screen Negative space on the screen Frame The printed image on paper
Screenprinting Methods Stencil Techniques Cut stencils - cutting the design from a non-porous material and attaching it to the bottom of the screen Painted stencils - painting a negative image directly on the screen with a filler material Photo Emulsion Technique
Cut Stencils The cut stencil method can be used with kraft paper, contact paper or acetate film. The image is cut away from the stencil using an exacto knife.
Positive vs. Negative Space As we cut our stencils, we want to be mindful of the positive and negative space within our images. The positive spaces that you cut out of the stencil will allow the screenprinting ink to pass through the screen to the paper. Negative Space Positive Space
Painted Stencils Screen filler is handpainted onto the screen in the negative areas.
Photo Emulsion Method Photo emulsion is applied to the screen. Once dry, then the screen is exposed to bright light, thus “burning” the negative film image into the screen. Photographic negatives or computer images are commonly used. http://www.hobbydo.com/screen_printing/preparing_the_screen.htm
