"Visual artists need to take into account how much an image will be reduced when prepared for publication when choosing the pitch of a screentone"
I have removed the disambiguation link on pitch as I was unsure of which pitch it was referring to. Could someone with more knowledge on this subject please link it to the appropriate pitch from the list? Thanks :) --Marc11:06, 11 May 2007 (UTC)[reply]
A screentone saves an artist's time by allowing quick application of textures to line art where a hand-shaded area would not be reproduced in a timely or acceptable manner. Much like halftone, the size and spacing of black dots, lines, or hatches determine how light or dark an area will appear. Visual artists need to take into account how much an image will be reduced when prepared for publication when choosing the pitch of a screentone. Screentones can also be layered to produce interference patterns such as moire effects, or to simulate multiple sources of shadow in an image.[citation needed]
Different styles of screentone exist, variously intended to depict clothing, clouds, emotions, backgrounds, gradients and even objects such as trees. While the sheets are most commonly produced with black ink, there are also varieties in solid and patterned colors. Screentones can also be modified by lightly scratching the backing with a scalpel-like blade to produce starbursts and other special effects.[citation needed]
Manga screentone-like pattern (the polka dots on hair)
While computer graphics software provides a variety of alternatives to screentone, its appearance is still frequently simulated, to achieve consistency with earlier work or avoid the appearance of computer-generated images. It is sometimes accomplished by scanning actual screentone sheets, but original vector or bitmap screen patterns are also used.[citation needed]
