High Definition Skia Photography (HDSP) is the name of the new,
revolutionary printing process that delivers photo prints of
unprecedented quality on conventional offset paper and reproduces
even the finest textures and details. This new technology, which
works directly from the negative - the skiagraphic image - produces
photographs without the need for a darkroom.
To mark this breakthrough, the inventor of HSDP, Dieter
Kirchner, and Heidelberger Druckmaschinen AG (Heidelberg) are
organizing an exhibition of around 50 photographs at the Print
Media Academy in Heidelberg from July 20-24, 2009. These will
include contributions from notable photographers such as Dieter
Appelt, Manfred Hamm, Ulrich Mack, and Jim Rakete - all of them
produced using HDSP.
All the photos in the PMA exhibition were printed on
Heidelberg presses. The necessary quality is achieved by ensuring
the right interplay between press, software, and consumables - ink
"We are delighted to be hosting this exhibition for all lovers
of quality photography and, in so doing, are reinforcing our claim
that Heidelberg solutions set the benchmark when it comes to print
products representing the ultimate in high-end quality,"
states Dr. Jürgen Rautert, Member of the Management Board
responsible for Marketing, Sales, and Service at Heidelberg.
The exhibition at the Print Media Academy in Heidelberg runs
from July 20-24 and is open from 9 a.m. to 5 p.m. Anyone who is
interested in seeing the photos is welcome and entry is free of
How does HDSP work?
In High Definition Skia Photography, negatives, slides or
raw data are recorded in two different digital data sets. An
electronic darkroom program uses this data to calculate all gamma
curves that are of relevance to the developing process for printing
purposes. Based on a defined digital image, the photographer
adjusts the paper gradation as he previously did in the darkroom.
Prints are produced using special inks adapted to the developer
substances. This also turns the press into a darkroom, the key
difference being that the printing process is reproducible. This
printing technology is based on a new standardization process for
uniform, optimized color separation and the design of the new
Heidelberg presses. As a result, it is possible to print even short
runs with barely perceptible fluctuations in tone.
Since conventional photo paper only has a limited image
gamut, around a third of the optical image gamut is cut off. HDSP,
on the other hand, exhibits an image gamut that lies at the limit
of visual perception. For the first time, all visible components
captured by the camera are transferred to the print. Given that the
three-dimensional perception of paper prints depends on the image
gamut and simultaneous contrast, an HDSP print achieves a high
