Heidelberg's frequency-modulated screening technology
Satin Screening causes sensation at Thieme
Only recently has Heidelberg marketed Satin Screening, its
optimized frequency-modulated (FM) screening. The print shop Thieme
in Meißen has already started using the new technology and
owner Ulrich Thieme has only one word to describe the first Satin
print results: "Terrific!"
Ulrich Thieme has gained first-hand experience with FM
screening since it was first marketed. Already in the 1990s, he has
been using Heidelberg's first-generation technology Diamond
Screening. The majority of his customers have meanwhile switched to
FM. When Heidelberg announced the introduction of Satin Screening,
a further development of FM screenign technology, Ulrich Thieme was
immediatly willing to test it within the Prinect Printready
MetaDimension workflow of his ongoing production runs.
Smooth vignettes, crisp pictures
The improvements Satin Screening brings are based on
an entirely new microstructure of the screen: Individual dots merge
to random patterns very early on. Bow shapes are produced which
generate a harmonious smoothness in the midtones and sleek
vignettes. The screen also provides an advantageous
circumference-area ratio and high process and color stability.
Ulrich Thieme confirms that "the print results are very good.
I would not have thought that it would be so unproblematic and look
so great right from the start. Really terrific!" Based on his
previous experience, he adds: "Vignettes, technical screens
and even halftone vignettes of images turn out considerably gentler
and softer. The screens are smoother and less disturbing."
Important prerequisites: Process calibration and process
control
When using FM screening, accurate process
calibration and permanent process control are essential
preconditions for obtaining premium-quality results. To achieve
this, customers can rely on Print Color Management (PCM) which
ensures the precise harmonization of all printing processes in
prepress and press. A trained PCM team will implement the necessary
adjustments at the customer's. The print shop Thieme also made
use of this service.
Ready for printing in less time
"To install PCM, you need professional support.
No print shop can do that offhand", Ulrich Thieme knows. In
the forefront of the installation, he and his employees had already
obtained information on PCM in Heidelberg. For Thieme, PCM brings a
number of substantial advantages. "All in all, we can start
printing considerably faster due to the standard values in the
machine." Waste is also reduced by 25 percent, according to
Thieme. "As the CIP3 data are incorporated and the PresetLink
sets the controls, only minor color corrections are necessary to
achieve the proof", says Thieme.
Combining FM screening and highly pigmented inks
After preliminary tests, the Thieme printers have decided on
a combination of FM screening and highly pigmented inks.
"Should the customer not wish a high-pigment coloring, we can
also print with standard coloring", the owner explains.
"However, if the customer wants, we can easily enhance the
coloring without ink change. We are therefore able to process all
jobs with one ink." The test results were so good that
everyone - printers and customers - is thrilled. "The colors
simply look more vigorous and brilliant, they are crisper, have
richer details and an extended color area", Thieme enthuses.
"We do not even have to open the pictures and save them again.
We can accept data from customers in any format or data file. And
without having to touch the data again, we can present a better
result to the customer than with an ordinary screen."
Increased use planned
Thieme meanwhile employs Satin Screening for 35 percent of
his print jobs - tendency rising. He is also pleased with the speed
of the plate recorder. No matter whether 70 l/cm screen, 80 l/cm
screen or Satin Screening, the Topsetter P 74 MCL retains a
constant platesetting speed. For Thieme, the biggest advantage of
Satin Screening is the color quality and the improved impression of
the printed image. Thieme consludes: "The excellent printing
result are not achieved by Satin Screening alone, but by its
integration in an optimal process chain harmonized from prepress
through to press."
