Digital pre-press part 1
Tuesday, September 22nd, 2009Digital pre-press part 1 – 22nd September 2009
This is the year of the hybrid workflow and digital printers are increasingly looking to add capacity with conventional offset and direct imaging presses. In order to get the most out of their new press investments, digital printers are looking at workflow systems to drive both static and variable data output.
Setting up a system to drive two different workflows isn’t desperately challenging or expensive. And, there are plenty of system developers who can tell digital printers where and how they can spend their hard earned money to do it. But that isn’t the hard part. The hard part is setting up a system so that the same job printed using two different production workflows, looks absolutely identical from press to press.
And it gets worse, because a print application might include some material with variable data and some without it, even though the majority of the job is the same. If the run is only a few thousand it is obvious that such a job can easily be printed using variable data software to manage the data flow and print the job on a digital press. If the job is tens of thousands thought, there needs to be tight colour management and control across both workflows.
Colour conscious
Quality control across devices isn’t just a concern for digital printers setting up hybrid workflows. It is also an issue for printers wanting to get equivalent colour quality across their fleet of digital presses. Fortunately suppliers have recognised that device profiling isn’t just a matter of creating a generic profile for their specific press technologies. We can then expect to see far greater improvements in colour quality this year as digital printers start to really get to grips with colour management, exploiting the device profiling tools that manufacturers such as Xerox with iGen3 press, are making available and to be shown at drupa this coming may. Being able to accurately profile an output device will help digital printers to improve their overall quality control, not just for individual short run work. It will also help them to maintain colour consistency throughout longer runs, and to ensure that subsequent reprints are colour accurate. To support hybrid workflows and to help ensure colour output quality, developers such as EFI, Creo PODS and Fujifilm are introducing new workflow technologies capable of driving multiple devices and workflows. The idea is to have a front end system with the capacity to support any quality demands and to be able to run high speed digital presses at rated speed. The scope of technology options for such front end systems will be even greater in 2008 as developers increase the options and tools they include with their systems. New soft proofing options from FFEI with Realvue and Dalim with its Virtual Library technology will allow digital printers to extend their workflows across media. Both of these tools, developed originally for job phototype and remote production proofing, are ideal for presenting media online as part of a publication or job ordering system.
