Small dots, huge possibilities
Tiny dots placed at random intervals: this is the magic
behind 10-micron stochastic screening. This leadingedge print
technology breathes life into images by creating richer, more
vivid colours and a level of definition that can’t be
matched. For print projects that require impeccable accuracy,
10-micron stochastic screening produces images over three
times more detailed than conventional print techniques.
How does it work?
In traditional offset printing, dot patterns are equally
spaced in a rigid pattern. A variety of dot sizes are used to
achieve tonality, density and shading. Under magnification,
you can easily identify the dot pattern used to create the
image.
In the stochastic process, all dots used to create an
image are equally sized and are much smaller than those used
in traditional offset printing. The dot pattern is randomised
to allow a wider range of definition and dimensional
effects, as well as a broader spectrum of colours. Light and
dark areas are defined by using less or more dots to achieve
the variations.
The size of the dots used in the stochastic process is
measured in terms of microns. For those suppliers currently
utilizing stochastic screening, only a few have made the
signifi cant leap to 10-micron. The majority use 25- or
20-micron dots in their process. This means that the
equivalent line screen is 380 to 400, respectively. The
traditional offset print process typically offers 150- to
200-line screen with the most prestigious quality
requirements using 300-line screen.
The Lowe-Martin Group uses a 10-micron process, the
equivalent of 650-line screen.
What does this mean?
Projects printed using 10-micron stochastic screening have
greater detail, increased clarity and greater dimensional
effects, as well as better flesh tones for a more realistic
result. Colour is also controlled more effectively, allowing
for a broader colour spectrum with smoother gradations.
With 10-micron stochastic screening, the possibilities are
as large as the dots are small.
