Stencil Cut Screenprinting

  1. 1. Stencil-Cut Screenprinting
  2. 2. / <ul><li>[email_address] </li></ul><ul><li>[email_address] </li></ul>
  3. 3. Supplies <ul><li>screenprinting station (large board, at 2’ x 2’ with hinged clamps to hold the screens </li></ul><ul><li>silkscreen with wood frames covered with duct tape </li></ul><ul><li>masking tape and duct tape </li></ul><ul><li>white contact paper </li></ul><ul><li>sharpie </li></ul><ul><li>scissors and an exact-o knife </li></ul><ul><li>squeegie large enough for your silkscreen (1/screen) </li></ul><ul><li>manilla paper or newsprint; actetate or a large piece of lamination (large enough to go under your screen - this helps with registration) </li></ul><ul><li>screenprinting ink </li></ul><ul><ul><ul><li>palette knife or spatula </li></ul></ul></ul>
  4. 4. Cutting the stencil <ul><li>Use either a light box, light table, or a window to trace your image onto a piece of contact paper. You want the white side of the contact paper touching the drawing. Retrace your drawing with a sharpie </li></ul><ul><li>Using an exact-o knife, cut out your stencil. It is best to create a design that has few or no areas that are not attached to the main contact paper.  </li></ul><ul><li>The positive part of the image is what you are removing. You want to keep the negative portion to apply to the silkscreen. </li></ul>
  5. 5. Cutting the Stencil <ul><li>Gently remove the backing of your contact paper.  </li></ul><ul><li>Press the contact paper to the flat bottom of the silkscreen. The frame side up is the top. </li></ul><ul><li>Use duct tape to cover any gaps on the bottom you might have between the contact paper and the edge of the frame. </li></ul>
  6. 6. The Inking Station <ul><li>Plywood board </li></ul><ul><li>2 Hinges (Printmaking Hinges can be purchased or you can use regular door hinges and clamps) </li></ul>
  7. 7. Check the Squeegie! <ul><li>Make sure your squeegie is large enough to fit the image. </li></ul><ul><li>You want a squeegie that will allow you to make one singlepass, not multiple passes. </li></ul>
  8. 8. Acetate is for Registration <ul><li>Screw your frame into the hinges of your printing station.  </li></ul><ul><li>Make sure your flat side is on the bottom. </li></ul><ul><li>In this picture, you can see a piece of acetate over a piece of paper. Just tape one side of the acetate. The taped side will work like a hinge. </li></ul><ul><li>It will be used to register the screen for the paper and for using multiple screens for printing more than one color. </li></ul>
  9. 9. CHARGE! <ul><li>Charge the screen before you print. Use a palette knife to make a well across the top of the screen near the clamps. Don't lower the screen yet. Hold it above the printing surface. You can place a roll of masking tape under the edge of the screen near the clamps to help hold it in place while you charge it. </li></ul><ul><li>Holding your squeegie at a 45º angle, make several passes to fill up the print area with ink.  </li></ul><ul><li>If it seems like your screen is clogging up, then gently massage the screen by rubbing with the squeegie in the clogged area. </li></ul><ul><li>Once the screen is charged, it is time to lower the screen and print with a single 45º pass of the squeegie. </li></ul>
  10. 10. Ink Consistency <ul><li>Print once onto the acetate. </li></ul><ul><li>You want your printing ink to be the consistency of a very thick milkshake. </li></ul><ul><li>Too thin and it will leak around the stencil. </li></ul><ul><li>Use water to think it down, or you can use screen printing acrylic extender base. </li></ul>
  11. 11. Setting the Acetate <ul><li>Use the printed acetate to check your stencil and to help register your paper. </li></ul><ul><li>Tape down the corners of the white paper with masking tape - or make an L-shape to show where to place the corners of the paper. </li></ul>
  12. 12. Almost there! <ul><li>Lower the acetate to make sure the paper is in the right area for printing. </li></ul>
  13. 13. Ready to Print <ul><li>Lift the acetate away and fold it down on its hinges of masking tape. </li></ul><ul><li>Charge your screen. </li></ul><ul><li>Lower the screen and print. </li></ul>
  14. 14. Yeah it works! <ul><li>With every pass you want to bring the excess ink back to the well at the top. </li></ul><ul><li>Scoop and tap the excess into the well. </li></ul><ul><li>Charge and Print Again!! </li></ul>
