Glossary
Software Reference for Scanners
are taped in register in a sandwich so they can be
viewed together or separately. More common are
Matchprints®, Chromalins®, etc., where the four
layers are reproduced in register on one sheet which
is then laminated. The above proofs are all
photographic in nature and produce a hard dot
structure unlike ink, which bleeds. The final proof
type is a press proof, which requires expensive setup
and prep time. It does, however, simulate the press
run very accurately.
progressives
a four color ink proof made on press, where each
plate is printed separately and in various
combinations with the other three so that the four
color images can be properly evaluated for dot gain
and the overall quality of the color separations. Also
called “progs”.
prescan
photometry performed by the scanner before a
screen preview.
pseudo-color images
when colors are assigned to monochrome shades to
give meaning to areas in the picture. Often used in
satellite imagery to define vegetation and geological
information. Can also refer to simple tinting of
monochrome images, like oil-coloring BW prints.
RAM
Random Access Memory.
raster
a lattice of parallel lines used to represent an image
by varying the brightness of points on each line. The
raster is a regular pattern of thin, horizontal, equally
spaced bars.
