Resolution
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.
RGB
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.
RIP
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.
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.
Saturated (presentation) 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.
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 Moiré.
