RIPing The process of rastering or converting bitmaps and vector graphics
into raster images suitable to the screening parameters of the output
device. Files are RIPed prior to exposure or plotting.
Saturated color
A color where the high and medium values approach 100%. In a
saturated clean color, the values of the wanted colors are near 100%
and the value of the unwanted color is near 0%. For example, when
the color is red, 5% cyan, 90% magenta, 80% yellow is more saturated
than 30% cyan, 90% magenta, 80% yellow.
Saturation The strength of a color.
Screen angle
The angle of rows of halftone dots represented in degrees. During
output of films for reproduction, the dot arrangement of each
separation film is placed at a distinct and different angle to the other
separations. See also

Screen rulings
The number of rows of printing dots per inch on a halftone film. A
150lpi-screen ruling provides much better quality than 65lpi.
SEF
A printer page orientation, where pages are delivered short end first.
Shadows The darkest part of an image (original and reproduction) having
densities near to maximum density. In the reproduction, shadows are
printed with dot areas between 80% and 100% See also

specified, usually towards the binding, in order to compensate for
