Brush the glue over the entire surface of the printing plate, smoothing any lumps or puddles. Demonstrate how to apply the aluminum foil.In this session, the children will be gluing aluminum foil to their printing plates and drawing details and backgrounds into the foil while the glue is still wet.Set out small dishes of glue with brushes.Set out printing plates, foil, masking tape, and pencils.
Cut aluminum foil into pieces slightly larger that the cardboard.Note: The glue needs to dry overnight before using the plates for printing. Remind them to keep the cardboard flat so the wet glue lines will not run. After the children practice making glue lines on pieces of scrap paper, have them draw an animal or object on the cardboard with pencil, and then follow the lines with the white glue.Moving the bottle too quickly along the lines will cause the glue to skip and moving too slowly will cause the glue to puddle. Apply the glue by trailing along the lines, gently squeezing the container with the nozzle against the cardboard. Explain that the thickness of the glue line will make small details disappear, so they will be added in the next session when working with the aluminum foil. Start by making a guideline with pencil, filling the cardboard with a drawing of a single animal or object. Demonstrate how to draw on the printing plate with the white glue.Both of these processes are referred to as relief printing. This will create negative lines that will not get ink on them and will be the color of the paper when a print is made. In the next session, the children will be covering the printing plates with aluminum foil and pressing lines into the foil. Explain that when printing ink is rolled over the printing plate the protruding glue lines will get ink on them, so when the print is made the lines will be the color of the ink. In this session, positive, or raised, lines will be made with white glue. The children will experience two different approaches in preparing printing plates, which are used to transfer images to paper.Set out bottles of glue, cardboard, and pencils.Adjust the caps on the glue bottles to get a thin flow of glue.Sheets of glass or Plexiglas for ink trays.Cardboard with a glossy surface (approximately 6 x 8 inches).Liquid glue in small squeeze bottles (one per child).Relief printing, positive lines, negative lines, printing plate, brayer Making more than one print from a single printing plate.
