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.
A rendering intent method in which colors that fall within the output
color space remain the same. Only colors that fall outside are changed
to the closest possible color within the output color space.
When using this method, some closely related colors in the input
color space can be mapped to a single color in the output color space.
This reduces the number of colors in the image.
All printers, monitors and scanners have a gamut or range of colors
that they can output (or view in the case of a scanner). If a color needs
to be output and is outside the gamut of the output device, it must be
mapped or approximated to some other color, which exists within the
gamut. Rendering Intent enables you to compress out-of-gamut
colors into the color capability of the press you are using. You can set
any rendering intent value for

Colorimetric.
There are several methods that can be used when translating colors
from one color space to another. These methods are called Rendering
Intents because they are optimized for various uses. When working
with ICC profiles, it is important that you select the Rendering Intent
that best preserves the important aspects of the image. Each rendering
method specifies a CRD for color conversions. You can modify the
rendering method to control the appearance of images, such as prints
from office applications or RGB photographs from Photoshop.
