GLOSSARY
Background Cleaning
Image enhancement feature that whitens all areas above a
defined lightness level. Typically used to avoid noise,
stains or wear marks.
Black Enhancement
Image enhancement feature that blackens all areas below
a defined lightness level. Typically used to enhance text.
Blueprint
A white print on a blue background; especially used for
copying maps, mechanical drawings and architects’
plans.
Blur
Image enhancement feature that makes the image softer
and less sharp.
CAD Drawing
Computed Aided Design technical drawing: mechanical,
electrical/electronic, architectural.
Color balance
Adjustment of the ratio of Red, Green and Blue (or Cyan,
Magenta and Yellow) components, which aims at
producing a copy free from any unwanted color cast or
color bias.
Color Calibration (CLC)
The process of bringing the color printer system to
standard operating conditions.
Color Management
The process of controlling colors to obtain what expected
from a color reproduction device.
Copying
Reproducing an original image onto a substrate.
Gray Balance ramp
Sequence of gray patches, ranging from very light (white)
to very dark (black) shades, in a constant decrease of
lightness.
Gray Enhancement
Color transformation feature that makes all the colors that
are close to gray to be exactly gray.
Hue
Attribute of color that determines whether it is red, yellow,
green, blue, or some combination of pairs of these (e.g.
an orange can be 30% red and 70% yellow).
Image Enhancement
Any process which aims at improving the appearance of
an image. This can be done using filtering, transformation
or “threshold” techniques, e.g. edge enhancement,
blurring, sharpening, blunt masking, etc.
Inkjet printer
A type of printer that shoots fast drying drops of ink
through tiny nozzles to create an image on paper or other
material.
Lightness
The attribute of visual perception in accordance with
which an area appears to emit or reflect more or less light.
It distinguishes light from dark areas.
