Digital Printing and XML Technology in Graphic Production Planning
Prof. dr. sc. Vilko Žiljak
Abstract: We are setting new relations
in graphic communication through target languages whereas the testing
and evaluation are carried out in the digital printing environment.
Efforts are made to develop dictionary standardization for XML technology
and offer it to the many users in the printing business. Digital printing
is the ideal environment because it is attracting users linked with
design, computer science and graphics seeking new solutions for Web
communication and data display standardization on diverse media.
2. Individualised Print
3. XML News in Computer Science
First Premise: Data and data structure are divided from physical display programming and the designing of an organised report. Data is described – marked – with the help of an understandable language, in detail, with texts in native languages. Thus content identification is simplified and various users may use it for their various purposes.
Second Premise: Through the Internet technology one enters simultaneously into various data files, various data bases, various sources; forming a unique XML structure. This is the source of native data bases starting the typical XML structure. Thus the problems of software and hardware incompatibility are avoided. Independence in respect to computer type and operative system is at its peak and very much accentuated. Data bases are entered from any place, at any time.
Third Premise: Instrumental data is manipulated together with other data from the data bases, such as the one on production planning and control. Such data circulation is an interactive way of production control; machine operation regime change; adjustment of work process parameters aimed at achieving the optimal ones. Internet technology allows remote equipment parameter readings, the goal being to be informed in real time.
Fourth Premise: A dictionary is the beginning of standardisation.
XML technology requires organising of an expert communication dictionary.
The printing business has started creating the JDF industrial standardised
language for itself through CIP4. Through the printing business dictionary
a path is made for bringing closer printing business methods in production
organisation, calculations, warehouse maintenance, total exploitation
of printing house machine capacities. The Internet technology in printing
application must rely on a language that is independent of the machine
producers and end users in the printing works. A dictionary is the
beginning of serious co-operation between competitors, with the goal
being to improve all printing business production parameters. Integration
through the new printing business dictionary is becoming a reality.
XML does not require a language consisting of codes and abbreviations that only programmers understand, and even programmers are not very good at working with such technology after a certain period of time. In the first applications an English language base was insisted upon, especially in manipulating with machine data. As XML variables may be textual descriptions, it is suggested that the native language should be used for marking. There will be broader and greater motivation due to easier understanding of the contents.
Organisation of work groups specialising in the following areas is suggested:
1. Organisation of printing business data bases structure. Development of forms for data entry with belonging patterns. Development of one’s own “private” XML languages for personal activities.
2. Development of a native language for the printing industry and publishing applicable in XML technology. Development of translators for other native languages and other communication standards in graphic art.
3. Interface development between XML and relational data bases: MS
SQL server, Oracle, Access, Informix, because it is necessary to use
data from established computer systems.
4. Development of XSL, XSLT, XSL FO solutions for screen data display, PostScript, PDF.
5. XML pattern development for instrumentation, specific for printing plant machines. JDF characteristics study, application and information on new oncoming types of machines.
6.XML application and application of relational data bases for graphic product production calculation; making tenders for end users and work order making.
7. Organising picture albums, logotypes, graphic layouts. Organising data bases on printing techniques, material (paper, colours, toners, glues), with the adequate production speed standard, prices and time needed for performing certain job phases.
XML studying must become a part of all printing technology subjects, meaning that the contemporary system for technical training in graphic art must be altered most urgently. This is supported by the fact that there has not been a single article written about the negative sides of XML in printing industry practice. Without studying XML technologies in the very first school semester and without practising in writing one’s own XML languages, it will not be possible to absorb the material on contemporary orientation in the printing business.
5. Digital Printing and XML
We have chosen to experiment with digital printing by using Xeikon, Indigo, Xerox and Hewitt Packard. Two areas have been developed: Calculations for tenders and realization in various printing layouts. The project entitled “Kalkulacija” (Calculation) is based on a MSSQL server where the relations are set between:
- printing machine description (format, price, speed, ripping price,
The whole system is in the Internet explorer, interactive. By changing one parameter a new calculation is made on basis of the following parameters: number of copies, paper choice, printing machine choice, coverage of colored surface, number of colors per page, two-side/one-side print. Student works show two choices in respect to DOM interface presence for XML document acceptance. Pattern designs are completely individual. They may be discussed only as to input speed efficiency and data read out from the relational bases tables.
The second application series is in respect to graphic page layout resetting. XML elements are: page, title, sub-title, signature, paragraph, font, etc. – but in the native language. Elements are treated differently inside the XML application. This is where graphic designers show their greatest differences in design. Graphic design with a “Guttenberg” presentation for printing works and web design for the Internet are suggested.
Different solution presentations are prepared for taking place in real time with notebooks prepared as servers with installed Microsoft SQL servers. The server functions locally in the Intranet. The http://WebPoskok.fotosoft.hr system has been developed for exterior Internet demonstration that may be viewed from any place at any time and our intention is to demonstrate this during this lecture.
We are forcing individualization in order to get many original solutions,
calculation motivation, and the possibility of testing on basis of
digital printing. Subjects for study are completely open as to choice,
and there are situations proposed that may be applicable in reality
in the far future only: XML kiosk, printing without the presence of
the operator, selective choice of topics from daily newspapers, creating
of personal daily newspapers with target contents from various bases
of electronic daily publications.
