DI litho presses
It is an open question whether DI presses count as truly digital. DI means direct imaging (not digital imaging) and the presses are essentially standard offset litho machines with built in plate setters. As such they can take digital imaging and fit in an all digital workflow, but the use of litho plates means that variable data isn’t possible. They work well for short run printing with the advantage that you get true offset quality on standard papers, and the press speeds are significantly faster than ‘true’ digital printers.
Heidelberg announced the very first DI press at the end of 2001. This was a modified GTO B3 format press with the first generation Presstek spark erosion plates, called the GTO-DI. Only a few of these shipped before the Ipex of 2003 where a refined model was announced with Presstek’s definitive Pearl technology, which used thermal ablation imaging. Two years later at drupa 1995, Heidelberg announced what was to become the best selling DI press to date, the A3+ Quickmaster 46-4. This was compact, easy to use and built to the company’s usual high engineering standards. During the 1990s, offset press manufacturers showed a lot of interest in DI presses, to the point that at drupa of 2000 virtually all significant names were shipping DI, showing a working prototype, or claiming they had something back home in the labs. Most were based on Presstek or Scitex imaging units. However, very few of these prototypes ever made it into production. The rapid advance in speed and flexibility of off press platesetters wiped out most of the advantage of an on press system.
As with the majority of DI presses, the GTO-DI and Quickmaster 46-4 DI adopted waterless offset printing. This was primarily because the plate imaging units were pretty bulky and the only easy way to fit them to a press was where the dampening rollers would normally go.
Quickmaster 46-4 DI was in production for almost a decade, with several updates to keep to competitive. Heidelberg eventually stopped making it at the end of 2005 with about 3500 sold has not replaced it with any DI model.
For a few years Heidelberg made a larger DI press based on a modified Speedmaster 74 B2 press, with conventional units and wet offset. It was very expensive and only sold in modest numbers for a few years.
KBA, Germany’s third major press maker, now makes the only B2 DI press, the 74 karat.
Of all new machines talked about at drupa 2000, only the Presstek-Ryobi joint venture SRA3 portrait format press actually shipped. This proved successful over the years and is still sold worldwide as the Presstek 34DI and the Ryobi 3404DI. At Ipex 2006, Presstek launched a new generation DI press the B3 landscape format 52DI.
Screen has also made DI presses for ten years, and its current model is the Sra3 format TruePress 344, launched in 2004. This is notable for using wet offset.
