Twenty-first Century Printing Trends - Variable Printing (II)

The process of selecting variable database software begins with assessing the complexity of the use of variable printing, and then determines the degree of adaptability and scalability that this application requires. Low-end applications require moderate adaptability, but because the range of output anywhere is low to high, they require higher scalability. High-end applications include sophisticated graphics placement, multi-platform processing, and a large number of outputs. Therefore, the standards for adaptability and scalability are very high. When choosing software, one should be sure that its adaptive performance meets the plan's execution and the scalable performance meets the output's execution.
In addition to the adaptability and scalability of the software, users also need to know that some software is bundled with some kind of front-end or output device, and some can output variable data files like Post script files that can be sent to any Digital printing equipment.
5. Digital press selection:
When final prints are produced in variable printing, press performance is still an important consideration. Different digital printers have different production capabilities and costs. When dealing with highly variable data, it is important to choose the right digital press. In selecting a digital printer, the main factors for printers to consider are:
a. Cost: The price range for digital printers ranges from mid-price $2,000 (Canon CLC-100) to high-priced (Indigo's Ultra Stream and Xerox Docu Color 400DI) costs around $600,000.
b. Speed: High-speed digital printers such as Ultra Stream and Agfa’s Chromapress32Si, Canon’s CLC2400, and Xeikon DCP/50D are all capable of high-speed printing.
c. Multi-color printing capabilities: Most digital printers have multi-color printing capabilities, and some high-speed digital printers (such as Indigo's Ultra Stream) have seven-color printing capabilities.
d. Layout: The largest format inkjet printer can print a width of 72". Some manufacturers, such as Creo Scitex, Raster Graphics and Sign Tech, can print 196" widths.
Digital press selection depends on cost, speed, multi-color printing capabilities, and layout. Printers need to determine which of the four factors should be prioritized in order to make appropriate choices.
Developing object-oriented distributed database
The main driving force of variable printing is database technology. There are four major database models: hierarchical models, mesh models, relational models, and object-oriented models. Each model has different ways of representing relationships between record types. In order to adapt to the ever-expanding need for printing based on structured and variable databases, and also to include more complex data types, databases have become more complex. The latest trend is the object-oriented database, which provides a structure that can be used to define complex data relationships. Objects are the focus of data and information collection. The object-oriented database proposes a conceptual data relationship, which allows the database designer and printer not to care about how the data is physically connected.
For other database models, all consumer data has the same record structure. Object-oriented databases provide the flexibility to create a single record type change. For example, database designers use potential sources of information to identify potential consumers.
The available information includes income information obtained from a consumer voluntary questionnaire, information on household credit risk obtained from a credit questionnaire, procurement information obtained from lottery tickets and scanning technology, and business accounting from a store. The consumer's preference information on clothing obtained from the subscription information obtained from the magazine subscription form. The object-oriented database allows designers to define consumer data in different related fields. For an object-oriented database, the record type of each information is just a different consumer and does not require a series of separate commands.
Database management is a key task in variable printing. Object-oriented methods are often used to process and manage object-oriented databases. Therefore, each object that forms a database includes a method of operating on data. An object-oriented model requires a method that defines and manages data in a manner that is related to this method. In the object-oriented model, each set of data becomes an object, and the objects can be further combined into classes. The designer of the database can also define how data is processed in each object. The object's consideration of the inheritance of each method will increase the efficiency of the object-oriented database.
Databases are almost always shared by many users and uses. Database designers share data to make effective use of available resources and have more output. For example, a series of data shared by related industries provides each industry with consistent information about consumers, suppliers, business affairs, etc. These shared databases may also be distributed. A distributed database is a database in which data exists in more than one system in the network. These data can be stored, queried or updated at any point in the network. When allowing users of other addresses to use the same data, distributed databases provide the necessary data and information with special addresses. People who use a distributed database do not need to know the address of the database, but through the interaction of application programs, propagation software, and database management systems to confirm, set, and query the data and information that the database user needs.
There are two general methods of database distribution: address distribution and function distribution. In the method of address distribution, the database or database distribution sets the area according to the frequency of use of data and information. In all regions, each split is easy for database users. The functional distribution requires more processing functions than the physical address settings. The method of functional distribution is most effective only when the propagation network and the database are interconnected.
The following pattern is a system entry. It is based on the relationship between the production of variable print products and the object-oriented distributed data. The construction of each object-oriented distributed database includes several objects, and each object has a way and the ability to represent each other. Objects with common characteristics are grouped together to form a class. For example, classified consumers include target consumers, income status, credit, etc. On the other hand, the product/service object is a separate class. This method produces a potential consumer, a consumer who is listed in a planned, consistent domain object. The functional distributed database also provides time control information for variable printing. The variable printing workflow is exactly the same for most digital prints. The only difference is that in order to provide the correct target-specific variable information, each step of the variable print operation is more focused on data analysis and Content information analysis.
Conclusion The point-to-point micropropagation is to build a relationship that provides effective communication and a high response rate, creating a new opportunity for the print communication industry and becoming a new trend in the 21st century. Variable printing is the main medium for micro-dissemination and is a very useful value-added tool for marketing and dissemination. The efficiency of variable printing depends on the integrity of database and database analysis. The object-oriented distributed database allows database designers to effectively use any useful data in the network. The object-oriented distributed database printing system model shows the network structure of the variable printing workflow and database system. This system model provides a clear outlook for the field of graphic communications and a method of adopting this technology in the information age.
