Network Communication and Printing Publication (1)

Keywords: Network Communication ISDN ADSL
Today, the Internet, ISDN (Integrated Services Digital Network) and T1/T3 provide telecommunication, but they are not suitable for future telecommunication. Let's focus on Internet-2, ADSL, and wireless communications including direct satellites. In an all-digital workflow process where people continue to work hard to create print publishing that is not geographically constrained, the ability to quickly and automatically transfer digital files from one place to another has become an overriding priority. Just a few years ago, rapid delivery meant the use of express delivery or the use of evening delivery services. Today, although manual postal services are still used as a regular method in the prepress and printing industries, the share of express mail has dropped significantly. Nearly two-thirds of prepress and print jobs are now conducted electronically via modems, ISDN, and T1/T3.
E-mails are widely used by Modem to transmit relatively small text or image files in order to facilitate some corrections and supplements as well as tracking jobs. Although Modem's download rate reaches 56 Kbps and its upload rate reaches 33.6 Kbps, this rate is rarely reached during working hours. Because of the heavy traffic on the Internet during this time. In any case, E-mail is replacing a fax for the electronic transmission of a small number of text and image files.
For the transmission of larger pages and image files, ISDN has become the most powerful digital network in the publishing industry. Because ISDN's monthly fixed fee is lower, the bandwidth selectivity is larger, ranging from 128 Kbps to 1.54 Mbps. The bandwidth of the leased T1 communication line can even be reached. The ISDN charging method is that in addition to the monthly very cheap fixed fee, the ISDN user pays far according to the distance per minute and the transmission distance.
In the United States, ISDN started slowly because telephone companies or telecommunications companies were initially unwilling to provide ISDN services. Many parts of the United States now have ISDN capabilities. However, telecommunication companies still do not dare to compliment the services and services provided by ISDN, and their reliability is not satisfactory. The comforting aspect is that ISDN is based on international standards, while ISDN is widely used in Europe, Japan, and Southeast Asia. In Singapore, ISDN is just as convenient as ordinary telephone service.
Companies that regularly transmit large amounts of data may lease dedicated T1/T3 communications lines. Its monthly fixed cost is relatively high. The installation and operation of T1/T3 communication lines may include satellite communication connection technologies and therefore require strong professional skills.
Professional application systems Since the establishment and operation of ISDN and T1/T3 lines is not an easy task, many businesses are turning to professional systems and using their telecommunication networks for help. In the prepress and printing industries, some suppliers are taking advantage of this market opportunity by seizing the shortcomings of telecom companies responding slowly to the special needs of the printing industry. New companies that sell telecommunications hardware and software products such as DAX, Group Software (formerly Luminous) and Wam! Net (now 4-Sight), has captured most of the market share. The main players in this field are Angels and UPS, which are supplying digital transmission networks designed specifically for the printing industry.
One of the pioneers in providing professional systems for ISDN is 4-Sight. The company initially marketed hardware and software products in the UK, and subsequently successfully entered the emerging US market with its ISDN hardware and software companion products. Another company offering ISDN connectivity products is HermStedt. The company has moved into the global market and recently entered the US market after occupying most of the German market. The Boston-based DAX (Digital Art Exchange) operates around ISDN and has extended its technology to frame breaks, dedicated lines, custom networks, and the Internet.
Wam! Net company is a company established specifically to provide digital transmission networks for the printing industry. In the spring of 1998, the company acquired 4-Sight for $40 million. Users of the 4-Sight ISDN interface can now connect directly to the powerful Wam! Net digital network. The Virtual Network provided by Imation Publisher Software can be used as a stand-alone system or tied to Remote Proofing. Group Logic has developed core software for Virtual Network. The company sold the expanded version of the Mass Transitrio software to OEMs and users. (To be continued)
