![]() July 16, 2009: Based on recent developments, it’s been reasonable to assume that when it comes to printing photographs, the future lies with inkjet. Now, right out of left field comes a new printing development from offset printing equipment goliath, Heidelberg. ‘High Definition Skia Photography’ (HDSP) is the name of the new printing process which Heidelberger says ‘delivers photo prints of unprecedented quality on conventional offset paper and reproduces even the finest textures and details.’ This new technology produces photographs without the need for a darkroom. In High Definition Skia Photography, negatives and slides (remember them?) or digital raw image files 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. The photographer adjusts the paper gradation to suit the specific image as he or she previously did in the darkroom with a medium like Ilford Multigrade paper.
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, so multiple near-identical prints can be made. – Well, wacko! A $1000 A3+ photo printer also trumps photographic paper in terms of colour gamut, and the Heidelberg announcement studiously avoids any mention of inkjet technology (in which it has no particular strengths). Curiously, Heidelberg only acknowledges digital camera technology in passing, instead focusing on negs and slides. Of course, this is not pitched as an alternative technology for the home digital darkroom enthusiast – Heidelberg doesn’t sell anything much shorter than 20 metres long, with price tags starting at around $1 million.
It could, however, provide some competition to the commercial ‘digital offset’ and electrophotographic systems from Kodak (NexPress) HP (Indigo) and Fujio Xerox (iGen) which are being used to produce photo books and the like, or the commercial wide-format inkjet printers used for large poster and canvas prints.
