Stationery Production Accelerated By New System
Remote Publisher is a data-base-supported software system for Internet-based print work production.
Compared to an output on film or plate, all proofing systems come with severe disadvantages in that they use different RIP technologies, and process un-separated Postscript files, it further claimed.
There are countless other sources of error, such as non-installed fonts, problematic processing of RGB images and PDF files, and the most varied RIP versions on Postscript level one, two and three.
DI-Plot creates a digital colour blueprint from the internal, high-resolution bitmap files prepared in the RIP for output.

This is compatible with the most varied output systems, it is said.
The data manager starts the imaging only after the printout has been checked and passed - without second ripping - and thus avoids expensive spoiled sheets.
At the heart of DI-Plot are the de-separation and de-screening techniques.
DI-Plot de-rasterises the separated files necessary for the printing machine (which have already been provided with the screen width and angles), combines the separations, and enables the printout on colour printers and plotters.
The advantage of DI-Plot claimed Digital Information is that files have been ripped for the printing machine can also be used for the proof.
This ensures complete agreement between the proof and the final print.
Time-consuming repeat ordering and ripping of the same file could also be avoided.
This definitive blueprint is also essential in order to comply with international quality standards.
It prints out all necessary cutting and folding marks, as well as format crosses and control strips - and thus provides an option for checking all these important elements for accuracy.
The customer can be presented with a complete and definitive version of his job, which he can correct and certify before any printing plates or films are imaged.
The system can also emulate up to 10 spot colours, depending on the type of printing machine, even with five, six or more printing units.
All the user has to do is define the CMYK values that will represent the additional spot colours on the printout, or refer to a list of more than 8,000 pre-defined spot colours.
DI-Plot is CMS enabled and by including the ICC profile used for actual printing, a formproof can be shown to the customer that corresponds to the final printing process.
It can also produce PDF-files from fully imposed and ripped print forms and the files can be sent to any Mac or PC via network, ISDN or e-mail.
The files keep their full integrity, and can be checked on any monitor or printed out on any locally available printer.
Any colour printer or plotter can be used as an output device, as long as its printer driver runs on Windows and its printing format matches the corresponding printing machine.
Alternatively, the system can generate a range of image file formats, which can then be reprocessed in any other way.
It can generate CIP3 and 4 files for printing machine ink-zone control, simultaneously with the formproof and the files can be processed by all familiar control systems, such as Heidelberg CPC32, or MAN-Roland Pecom.
The ripped data is read from the RIP via existing network structures.
The PC with DI-Plot converts the bitmap files and outputs them to the color systems.
