Scratch art uses line and value as elements of art and pattern and contrast as principles of design.
Line: an element of art that is a mark withlength and directionValue: the lightness and darkness of a surface.Pattern: a principle of design thatrepeats lines and shapesContrast: a principle of design that shows an opposition between elements
Value is the degree of light and dark in a design. Changes in value can create contrast.
Engraving: a method of cutting or incising a design into a material with a sharp toolScratch board: illustration board in which black ink-coating is scratched away to reveal a white clay-coated surface
Scratch Art Exercise • Create a value/zone scale on the scratchboard from white to black including all of the shades of gray in between by hatching or cross hatching. • Students will move from black to white. Black will be left alone and each square will be gradually lightened. White will have all of the ink removed.
Tips for Scratch Art • Students will find an image of an animal that is high contrast, or can be made high contrast using Photoshop. The image must be 8” x 10” • Transfer image by lightly taping down the paper on top of the scratch art board and trace main contours with a pen. • When working on the paper, keep it covered with newsprint to prevent oil from you skin from going onto the paper. • Begin to scratch slowly. Remember you can always make it lighter, but you cannot make it darker. • Scratch in the direction of the desired texture. • Do not blow the dust off of the table or off of the scratchboard. Gently tap the dust on the table and wipe it into the garbage. • Negative scratching is a technique in which the design is formed by lines and shapes scratched out of the background of the paper. In other words the image is composed of lines and spaces shaped by the spaces missing from the inked background. It is a useful technique for designs that have fine lines, because it is easier to carve away a line than to leave a line standing. • Positive scratching leaves the lines and areas that is the image. This technique works best for designs with bold lines and simple shapes. These marks enliven the art with the kind of texture that is associated with this medium. Positive scratching is often combined with negative scratching in the same design.
