It's commonly accepted that print has a central position in multi-channel advertising and that in combination with a selection of digital'touches'it may significantly increase response rates. Electronic printing technologies of various forms are now actually in popular use, permitting personalised or variable data printing (VDP) to ensure that not only is the writing and picture content of every piece tailored to the individual beneficiary, even how many pages could be diverse to suit.

Today's innovative multi-channel marketing automation tools are a much cry from the straightforward mail blend of the 1990s and early in the day, or even the hybrid making of 10 years approximately before, when brochures or mailers pre-printed on offset squeezes may have personalised text overprinted with a electronic printing head.

Now, everything is produced afresh on each page. While that's no problem for toner or inkjet presses, it will possibly place an enormous burden on the electronic front conclusion (DFE) and the RIP that's to operate a vehicle the press. With the graphical complexity of customised parts significantly confined just by the designer's imagination, the processing period in making VDP careers may swiftly become a major output bottleneck.

Rather than imaging a typical page after for the electronic press and then printing it a few hundred or thousand occasions, there's to be an imaging method for each site, which is then printed once. Half-an-hour's wait before printing many hundred copies around several hours might be acceptable, but a minute's delay between every duplicate will be a output disaster.

Ideally, the press ought to be pushed at its complete ranked rate during a VDP printing run, which usually provides the RIP only fractions of another to get ready each new page. Poor design/file construction methods can seriously impede this. Poor practices contain unnecessary adding of items and haphazard usage of visibility outcomes, using photographs which can be at larger resolution than is necessary for print, or making vector art with unnecessarily large numbers of get a handle on items, for example.

To further confuse issues, there is number one method to create VDP jobs. There is many different publishing resources, ranging from easy plug-ins for popular graphic design computer software to dedicated cross-media generation suites that produce variable data print, email and other on the web resources from the same key material. With most of them it's similarly probable to produce VDP files which can be great or bad from the printability perception; they might - ultimately - create the same printing but can be greater or greatly worse in terms of whole running time and therefore job turnaround.

VDP'emitters'like this also use a selection of VDP'languages'to hand down the printing work to the DFE. Some are proprietary to specific equipment companies - IBM's AFP and Xerox VIPP, for example - and some are more generalised or start, such as PPML or PDF/VT. While these have been produced to explicitly support variable material, some originate from the text-based transactional printing world, while others are firmly targeted at graphically-driven marketing and promotional applications.

There are several important differences in the capabilities of those print formats, especially regarding design handling and particularly in the degree of help for sophisticated functions such as for instance transparency. The ability to critique the VDP printing stream for examining purposes differs also: the older formats do not support any previewing at all, whilst the production record is assembled just at printing time, while PPML careers could be tested but just with a passionate viewer. PDF and PDF/VT could be previewed applying any PDF observing application. Whatever DFE or RIP a printer has, it should have the ability to accept and method VDP documents in the format that the customer or inner facility can supply.

Options by which VDP structure pc software, hand-off language, DFE/RIP and digital push are typical produced and reinforced by exactly the same merchant are one answer, and should promise compatibility and productivity but they may lack flexibility. If the entire VDP file design, database administration, document structure, running, printing and finishing routine is carried out beneath the printer's ceiling then restricted integration between components need to generate a successful solution. But what are the results whenever a new customer wants to manage their own repository to create and deliver differently prepared VDP documents for output? What if a fresh campaign strategy calls for graphical functions in the produced material that are beyond what is currently supported?

The alternative is always to choose a production program that could accept insight in any of the common VDP models and that has the necessary power and flexibility to function productively with all of them. A great system would also have the capability to drive multiple produce or type of digital press. This increases long-term freedom and increases get back on investment as the business develops and new speed, finishing or quality choices become available.
