The number of pixels, points or dots per unit of linear measurement.
For example, pixels per millimeter on a video display, number of dots
per inch or millimeter on film or paper.
The resolution of an image is usually set the same vertically and
horizontally. For example, a square millimeter with a resolution of 12
contains 144 pixels. The higher the resolution, the more image detail is
recorded and the larger the digital file size.
Abbreviation for the additive primaries Red, Green and Blue. They are
used in video monitors, scanning, and other uses where the light is
direct and not reflected. The component colors are the three
predominant colors in the visible light spectrum detected by the
human eye. Combining these 3 colors together creates white light.
Abbreviation for Raster Image Processor. This is a software program or
hardware device that converts vector information into pixel
information to be imaged on an output file. This output file is imaged
based on commands from the page description language.
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.
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.
A rendering intent method which scales all colors to the strongest
saturation possible. The relative saturation is maintained from one
color space to another.
This rendering style option is optimal for artwork and graphs in
presentations. In many cases, this style option can be used for mixed
pages that contain both presentation graphics and photographs.
The strength of a color.
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 Moiré.
The number of rows of printing dots per inch on a halftone film. A
150lpi-screen ruling provides much better quality than 65lpi.
A printer page orientation, where pages are delivered short end first.
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 Highlights
and Midtones.
