Class Information: 

Scratchboards are essentially a reductive approach to creating black and white ink drawings.  I believe their unique advantage is that they flip the traditional approach of adding black ink to white paper and instead the image is created in reverse by drawing the white areas into a black ground.  This perceptual shift leads to many unexpected and interesting results, and can give the artist fresh insights into the experience of drawing and composing images.  For me, the results are often more compelling than the additive approach, and also full of rich details and textures that can’t easily be obtained any other way. 

 The “scratchboard” itself is a fiberboard panel covered with a smooth white clay ground and evenly coated with black India ink.  Drawings can be created on this surface by scraping or scratching away the black ink to reveal the white ground underneath.  The result is typically a very high contrast drawing with crisp details and a carved “woodcut” relief printed look.  In addition to this, additive techniques (corrections), color, texture, creating gray tones, cross hatching, working from a white ground, finishing and sealing the panel, and the use of various tools will be explored in the class.  We will also discuss the expressive potential of scratchboard drawings and some of their unique characteristics related to developing content.
