Plastic Letters

PlastigraphThe Plasti graph lettering system depends on the natural surface tension between the plastic letters and the board for its effectiveness. This phenomenon creates a natural adhesion between the very smooth thin plastic plasti graph letters and the smooth surface of the board or even a smooth material like glass. This same surface tension allows some insects to walk on water! The thin plastic letters come in different attractive colors, sizes and typefaces and are available at a very reasonable cost from a large stationary supplier.

Surface Tension

Typefaces"Surface tension is the elastic tendency of a fluid surface which makes it acquire the least surface area possible." Plasti Graph, which is the proprietary name for this material, uses this special property for highlighting key words during a talk. The plastic letters are preformed as no artistic skills are required aside from placing them in the correct position on the board or shiny surface. In preparation, the lettering may be set up on pieces of clear film or tissue paper. Extra care needs to be exercised to ensure they are absolutely straight on the board.✞

Key Words

LetteringEach key word used in a talk may be separated from the next with a sheet of tissue paper before placing on the display board. For further information see also Communicating Word Meanings.
