A file of data that was scanned, processed or output sequentially, bit
by bit and line by line. Also known as a bitmap.
The translation of vector information into bitmap information.
Bitmaps may also require a new rasterization to comply with the
screening parameters (dot shape, dot size) of the imagesetter that will
expose them on film. See also RIP and RIPing.
Fitting of two or more printing images or plates in exact alignment
with each other.
Crosses or other targets applied to original copy prior to printing.
Used for positioning films in register or for register of two or more
colors in process printing.
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.
