A GFA B ALANCED S CREENING T ECHNOLOGY (ABS)
Line screening and halftones are factors that highly influ-
ence color image rendering. In conventional printing, color
images are composed of tightly arranged dots (or halftones)
that are spaced in a regular pattern and appear solid to the
eye. Tonal changes are made by changing the size, or ampli-
tude, of each dot. This technique is known as amplitude
modulation, or AM screening.
MINOLTA-QMS’ Color Control System can apply many dif-
ferent types of halftones. The magicolor 7300’s halftones are
licensed Agfa ABS screens. Agfa Balanced Screening (ABS)
technology is a patented conventional, halftone screening
system that uses supercell techniques and pre-calculated
balanced screen sets to deliver the highest quality color
reproduction in the industry.
ABS-Screened halftones feature clear-centered rosettes for
smooth tonal gradations and tints, and flawless skin tones
free of moiré patterns. The technology is designed to mini-
mize printer noise and produce consistency in image quality
within a page, from page to page, over time and across
difference devices. Agfa Screening minimizes color balance
shifts due to registration error, optimizes color gamut,
neutral balance and neutral balance stability, diffuses
jaggedness and subject moiré, minimizes banding and
eliminates “rainbow” effects.
Agfa ABS screening can provide the equivalent of approxi-
mately 256 levels per primary color—for a total of up to
16.8 million colors (limited by what the human eye can
perceive). At a comparable line screen of 150 lpi at 1200
dpi, traditional screening is only capable of 65 levels for a
total of 274,625 colors.
