Message definition (AY Honors/Silk Screen Printing/Answer Key)

</noinclude>

*a) a '''screen''' made of porous, finely woven fabric (originally silk, but typically made of polyester since the 1940s)
*b) stretched over '''a frame''' of aluminum or wood areas of the screen are blocked off with a non-permeable material to form a stencil, which is a positive of the image to be printed; that is, the open spaces are where the ink will appear.
*c) The screen is placed atop '''a substrate''' such as papyrus or fabric.
*d) '''Ink''' is placed on top of the screen,

*e) and '''a fill bar''' (also known as a floodbar) is used to fill the mesh openings with ink. The operator begins with the fill bar at the rear of the screen and behind a reservoir of ink. The operator lifts the screen to prevent contact with the substrate and then using a slight amount of downward force pulls the fill bar to the front of the screen. This effectively fills the mesh openings with ink and moves the ink reservoir to the front of the screen.
*f) The operator then uses '''a squeegee''' (rubber blade) to move the mesh down to the substrate and pushes the squeegee to the rear of the screen. The ink that is in the mesh opening is transferred by capillary action to the substrate in a controlled and prescribed amount, i.e. the wet ink deposit is equal to the thickness of the stencil. As the squeegee moves toward the rear of the screen the tension of the mesh pulls the mesh up away from the substrate leaving the ink upon the substrate surface.
