Value and Color Progressions
Value or color progressions are essential when using the reduction woodcut process. For a single block reduction, there is a simple value progression through the multiple carve-and-print stages. When using multiple blocks that are each reduced between printings, different value or color progressions can be assigned to each block.
A value progression is multiple values and colors layered over one progressing from light to dark. Each successive layer defines a progressively darker area of the image.
A simple value progression is moving from light to dark in three values. A color progression is moving from a pale color to a deeper hue of the same color and a two color progression moves from one color to another, each with gradations in between.
The image is carved away or reduced between each printing (color run).
