Other methods include layering arbitrary intersecting patches. At its simplest, a layer of linear hatching is laid over another layer at a 90° angle, to which further diagonal layers may be added. Crosshatching Layers of hatching applied at different angles to create different textures and darker tones. Normally the lines follow the direction of the described plane. Variations Linear hatching Hatching in parallel lines. For example, red might be made up of lightly spaced lines, whereas green could be made of two layers of perpendicular dense lines, resulting in a realistic image.Ĭrosshatching is the technique of using line to shade and create value. Line work can be used to represent colors, typically by using the same type of hatch to represent particular tones. By increasing quantity, thickness and closeness, a darker area will result.Īn area of shading next to another area which has lines going in another direction is often used to create contrast. Hatching lines should always follow (i.e.

The main concept is that the quantity, thickness and spacing of the lines will affect the brightness of the overall image and emphasize forms creating the illusion of volume. Master ES and Martin Schongauer in engraving and Erhard Reuwich and Michael Wolgemut in woodcut were pioneers of both techniques, and Albrecht Dürer in particular perfected the technique of crosshatching in both media.Īrtists use the technique, varying the length, angle, closeness and other qualities of the lines, most commonly in drawing, linear painting and engraving.

In Western art, hatching originated in the Middle Ages, and developed further into cross-hatching, especially in the old master prints of the fifteenth century. Hatching is especially important in essentially linear media, such as drawing, and many forms of printmaking, such as engraving, etching and woodcut. Hatching is also sometimes used to encode colours in monochromatic representations of colour images, particularly in heraldry.

When lines are placed at an angle to one another, it is called cross-hatching. Hatching ( French: hachure) is an artistic technique used to create tonal or shading effects by drawing (or painting or scribing) closely spaced parallel lines.
