Digital printing features 1. Good file compatibility and easy operation. Digital printing can accept the output printing of computer files such as Photoshop, Freehand, Pagemaker, Quarkxpress, CroelDraw, etc. and the general documents and images are first edited on a computer and then output printed, and the digital printing data source can be directly obtained from the internet. The client transmits his or her graphic information to be printed to the printing professional company he or she is satisfied with. The printing professional company will perform various processing and then transmit the proofing effect to the customer via the Internet. If the customer is satisfied, he can directly go to the machine. print. Digital printing has low requirements for documents, and it can accept various formats of Mac and PC files that are favored by designers of many advertising agencies. It is also convenient and fast for the reception and processing of remote PDF data information. The speed of digital printing.
2. The process flow is greatly simplified and the customer's delivery time can be met more quickly. After digital printing receives customer's satisfied computer files, it can directly generate PS files through fast software and hardware RIP; it can also be directly divided into four-color film through electric sub-system. After printing, it can be processed by printing plate with ordinary printing plates. print. Digital printing usually prints one or two proofs of a printed matter. After the standard test strips are tested and debugged, the finished products can be printed, and the customers are not satisfied with the defects directly, convenient and timely, and the traditional printing process, including output power distribution, Compared with the procedures of proofing, imposition, printing on the PS, and on-machine, it greatly saved time and reduced production costs. Prints that can usually be delivered in 3 or 4 days can be delivered in just a few hours.
3 personalized printing, the number of random, can be printed at any time, modify. The personalization of digital printing is particularly obvious. For example, a partial image of a printed product needs to be replaced. In digital printing, it is only necessary to directly replace the image. The number of prints can be from 1 to several thousand, from the perspective of price and quantity. In terms of printing, it is suitable for tens to hundreds of copies. In addition, if a customer prints in a few days after a print, they can directly print the RIP-ready file directly from the digital printer, and print it directly after the revision, instead of re-outputting the electricity segmentation as in the traditional printing. , proofing, printing, etc., there is no loss of material.
4. Can print on both sides at the same time. The software and hardware RIP of the color digital printing system can complete the double-sided printing. When the double-sided printing PS file generated according to the customer's requirements is transmitted to the digital printing system, the digital printing system is rasterized by the RIP to form the positive and negative sides. Two sets of CMYK printing units, through computer control, can combine two different computer files into positive and negative sides, and can complete double-sided printing at one time. The two sides have the same size and alignment, and no color copier or laser exists. The proofing machine can only complete single-side printing at a time and the alignment is more difficult.
5. Multi-page support system. Color digital printing comes with a large memory for multiple colors. If each color is equipped with 72MB of memory, that is, CMYK4 color has a total memory of 288MB or more, 68 pages of A4 files can be continuously printed, and one page can be printed in accordance with the page order to facilitate binding.
6. Process simplification Suitable for short-run fast color printing. Digital printing system process simplification is more suitable for the current development trend of the printing industry, small batch, personalized, fast and other features, printing speed up to 4200 / h (A4 single-sided full-color printing) or 2100 / h (two-sided ).
Digital Printing Development Prospects
Digital printing technology was developed in the 1990s. Heidelberg, Germany exhibited the GTO-DI digital press on the 1991 Print'91; Israel's Indigo introduced the E-Print 1000 digital press on the Ipex'93, and Belgium's Xeikon. The DCP-1 digital press was introduced. Since then, Xeikon has given technology OEMs to AGFA, IBM, Barco and other manufacturers. On Drupa'95, several companies have exhibited their own digital presses, pushing digital printing to a development. climax. According to a report from Xerox Corporation in 1997, the annual global color printing products are about 34.8 billion pounds, of which one-third of the tasks can be completed by digital printing technology; the statistics of the famous American market research company CAP Ventures in 1996 showed that the world’s black and white in 1996 The sales volume of the digital printing and publishing system increased by 21% over 1995 and increased by 26% in 1997. The global development trend is that large printing machinery manufacturers are rushing to develop their own new products, and the format is becoming larger and larger. Graphic information can be stored or erased. After Drupa'95 in China, some companies have also introduced digital printing systems. At present, there are nearly 60 sets of GTO-DI digital presses in Heidelberg, together with about 100 sets of products from companies such as Indigo, Xeikon and AGFA. about.
There is still a certain gap between China's economy and the economic development of western developed countries, and most of the state-owned enterprises have poor results, which will inevitably affect the development speed of digital printing technology in China. Eastern coastal areas such as Shanghai, Guangzhou, Shenzhen and other economically developed cities have a certain amount of demand. The economically underdeveloped regions in the Mainland will not have much demand. Therefore, Chinese printing companies must do a good job in market research when introducing equipment. Remember to introduce blindly. !
