Amplitude is
Modulated Dots change in size from small to large,
but equal distance from center-to-center 150 lpi, 175 lpi,
etc
Frequency is
Modulated Dots are all highlights in size and only
the distance from one-to-another varies Measurements in
microns
What is
Staccato?
Staccato is the CREO version of stochastic
screening. Where conventional screening (AM) is lines of dots
the same distance apart and varying in size. Staccato (FM) is
a random pattern of dots all the same size (only much
smaller).
Why is
Staccato Better?
Because you are controlling a much smaller
dot that does not have to be arranged in rows, it creates many
advantages over traditional screens.
1) Wider color gamut- printers cleaner
with greater vibrancy 2) Presswork Stability 3)
Color Stability 4) Make Ready Much Faster 5)
Tighter Registration 6) Eliminate Moire Patterns
