PSImage
A low-resolution EPS file that is part of the Automatic Picture
Replacement (APR) workflow. You use PSImage files to position
images in page layout. You can create and edit a PSImage file in
various applications, such as PSImage Exporter in Adobe
Photoshop, Copydot Toolkit, and oXYgen software. If you edit a
PSImage file (for example, you add a mask or a clipping path), the
workflow software applies your changes to the high-resolution file
and automatically replaces the PSImage file during the RIP
process.
relative colorimetric
A method of color matching. When translating colors from one
device to another, it retains the colors that fall within the range of
both devices.
RGB
Abbreviation for the additive primaries—red, green, and blue.
These colors are the predominant colors in the visible light
spectrum that the human eye can detect. The RGB colors are
used, for example, in video monitors, scanners, and other devices
in which the light is direct and not reflected.
rich black
A black area to which layers of other inks, referred to as support
screens or booster colors, have been added to make the color as
dark as possible.
RTP (ready-to-print) job
A job that has been RIPed and is in the appropriate format for
printing. You can submit RTP jobs for reprinting without
reprocessing them.
screen angle
The angle at which a halftone screen is set for printing halftones.
Proper screen angles minimize moiré patterns.
