"Heidelberger announces new printing process
Press manufacturer Heidelberger Druckmaschinen AG, Heildelberg, Germany, announces the first exhibition of photographs printed with the High Definition Skia Photography (HDSP) process.The HDSP printing process delivers high quality photo prints on conventional offset paper, reproducing fine textures and details. The new technology, which works directly from the negative -- the skiagraphic image -- produces photographs without the need for a darkroom. According to Heidelberger, the necessary quality is achieved by ensuring the right interplay between press, software, and consumables -- ink in particular.
Dieter Kirchner, inventor of HSDP, and Heidelberger Druckmaschinen are organizing an exhibition of around 50 photographs at the Print Media Academy in Heidelberg from July 20-24, 2009. It will include contributions from notable photographers, with all photos printed on Heidelberg presses.
In HDSP, 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.
Unlike conventional photo paper, which has a limited image gamut, HDSP exhibits an image gamut that lies at the limit of visual perception. All visible components captured by the camera are transferred to the print."
