Digital printing is the development direction of printing technology. According to the statistics of the British Paper Printing and Packaging Technology Research Association (PIRA), digital printing currently accounts for about 9% of the printing market. It is estimated that this figure will rise to 20%-25% by 2010. The development of digital printing is closely related to the development of digital networks. So we say that the basic technology of digital printing is network technology. This is because, although digital printing still requires the necessary prepress processing as traditional printing, the digital files formed by prepress processing do not need to be immediately printed, but are stored digitally or transmitted via digital networks. Offsite, and finally, complete the printout according to the customer's order requirements. Therefore, this is a brand-new production method based on "digital flow + digital media/high density storage + network transmission". Of course, it will not be limited by time and area like traditional production methods. With the development of technology, in fact, as long as the area covered by the network, regardless of the distance, can realize the real-time transmission of products (digital files / pages), and print out according to the requirements of customers. Therefore, it can also be said that traditional printing is a production mode of “production and then salesâ€, and digital printing is a production mode of “reproduction and productionâ€. Therefore, once digital printing is combined with the Internet, it can build a global on-demand production and service system to meet the needs of the gradually developed and personalized printing and publishing market. The two most critical technologies in digital printing application technology are software RIP and hardware-based digital printers. If 100% variable information is to be printed, and the adjacent two prints can be completely different, and also require a very high printing speed, then RIP will have a high printing speed. And with the continuous improvement of the requirements for digital printing quality, the resolution is also increasing, which further demands to improve the RIP performance. The requirements for digital printing equipment are even more obvious. The main goal of the digital printing technology solution is to shorten the production cycle, shorten the production process, realize the last minute modification, eliminate the hidden cost of short-term document printing, improve the printing quality, achieve rapid color printing, improve the ease of use of equipment, and provide More applications than existing methods. Equipment suppliers have launched a total solution to meet these requirements. Not only Fuji Xerox, Indigo, but also the traditional printing equipment supplier Heidelberg have joined. As far as digital printing machines on the market are concerned, they can be mainly divided into two types: unregistered digital printing machines and digital printing machines. The current non-printing press can be divided into three types of electrophotographic methods, electrocoagulation methods, and inkjet methods from a large aspect. The common feature of unprinted digital printing is the realization of variable information printing. With digital presses, there must be preprinted plates on the plate cylinders, except that they are made directly on the press. Compared with traditional printing presses, although this type of printing press also needs a printing plate, since it is a direct plate making machine, only one printing machine can complete the production process from data to printed matter, which saves equipment. , time, materials, and reduced production costs. The above-mentioned digital printers print the layout information in digital form. Therefore, how the network or database data is correctly transmitted to the printer is a key issue. In the entire process of data transmission, the bottleneck must be clearly identified in order to increase production efficiency. Digital printing has emerged from less than a dozen years ago, but it has grown into an advanced technology with printing quality close to traditional offset printing and huge business opportunities. Indigo founder Benny Landa once said: “Everything that can be digitized will become digital, and printing is no exception.†Digital printing technology continues to advance, and the potential of digital printing is still being explored. We also have good reason to believe This is a printing method full of vitality.
