In today's major printing methods, the development of flexographic printing is one of the best! By 2010, the flexo printing will increase from the current 10% to 22%, and the other printing methods will be reduced correspondingly. Among them, offset printing will be reduced the most and will be reduced from the current 46% to about 30%. With the development and application of some high-tech prepress technologies, people are optimistic about the development of flexo printing.
I. The Impact of Digital Technology and Networking
The ever-changing prepress technology is the main reason for the rapid development of flexographic printing. According to reports from the United States, flexographic printing has accounted for 60% of packaging printing in the entire Atlantic region, with an annual growth rate of 7%-8%, and some astute printers are also considering turning to the flexographic printing market. One development trend is that the prepress processing cost of flexo printing is getting lower and lower, and the operation is more and more convenient. Recently, many imagesetters such as Purpp-Eskofot's products can adapt the screen angle to different printing methods and print suitability. Digital proofing systems, such as Imation's Rainbow proofing system and DuPont's digital Cromarting proofing system, use spectral methods to simulate the conditions of the flexo output. Although some printers nowadays are pursuing high-quality prints to configure expensive high-end systems such as Barco Graphics, there is no need to configure high-end systems for package design and copying of originals. Application software on the desktop system can complete the design of the original. It is the above reasons that bring great convenience to the printing staff.
As people pay more and more attention to the appearance of goods, some printing companies with advanced technology and equipment have become an important part of the packaging of goods.
At the EFTA flexo printing conference held in Birmingham, United Kingdom, in 1998, Jeff Walton pointed out: "Over the past five years, flexographic printing technology has made considerable progress." In order to adapt to the market competition, the development of prepress technology is mainly reflected in four aspects. First, use advanced communication facilities such as the Internet for data transmission. Second, to improve the color management system, the color management system should take into account each of the influencing factors in prepress processing. Third, use digital technology to increase the reliability of proofing. Fourth, apply the latest digital platemaking technology to improve quality. In fact, Brent Imaging has already provided these services. The company recently showed people an Internet-based database network Datanet. Through the Datanet network, the desired enlarged or reduced image can be obtained from the database of the network, and the guiding suggestions can be sent by E-mail to obtain high-quality proofing samples. Once the design results of the advertising design creation company are online, they can be browsed and loaded by professionals and designers. In other words, space obstacles are weakening and even plate making can transmit data over the Internet.
Second, the impact of CTP technology
In fact, in the future there will be many new products for ctpp (computer-to-polymer). As Grantham Harris, UK sales manager at DuPont Packaging and Printing, puts it: “There are many efforts dedicated to UV flexographic research. DuPont and Barco are working together to develop a dual light source with high sensitivity. (There is no decrease in resolution of the CTP plate.)
Of course, DuPont is not the only manufacturer that produces CTP systems. There is a new system, CreoThermaflexo, which is capable of thermal imaging on DuPont's digital Cyrel media with an imaging size of 1270 × 1700mm. At the same time, there are two smaller CTP systems, which are the Barco and DuPont CDIC systems and the Wetzel/BASF Flexosetter WFL40-2 system, which are aimed at the trademarks, labels, and corrugated box printing market.
DuPont also introduced two digital plates, the Cyrel.UVP and the DPU, which do not suffer from dot gain problems when printing with UV inks, unlike traditional printing plates.
At present, people favor the Omnisetter system. The main reason is its applicability. The Omnisetter system can generate a single geometric shape dot, a random dot or a regular dot, or a combination of these three dots. In addition, the Omnisetter system can image not only flexographic plates but also conventional offset plates and infrared dry films. This performance has made people realize that ctpp will not completely eliminate the traditional plate-making method in a short period of time.
At the same time, some people think that the best imaging method is laser engraving imaging. Although this technology has been used for many years, it has only made some progress in recent years. The drawback of this technique lies in the limited range of tone reduplication when copying fine prints. The ZED system is said to use HS laser electron optics technology, which can copy high-grade prints.
Third, the development prospects of flexographic plate
The recent articles involving flexographic printing will mention the problem of environmental pollution caused by chemical treatment liquids in the process of plate making. Dupont’s Grantham Harris said: “The plates produced by DuPont are good, but we don’t Forget about the scum produced during the processing of the plates, now is the time to solve this problem. Another type of plate that we are working on has already taken shape in Germany and will soon appear on the British market. Limited to the size, only for some trademarks and packaging printing."
The most widely used in flexographic printing is a photosensitive polymer compound plate. Recently, water-treated plates, such as the Flexceed ZX plate of the Supratech Systems (Europe), have been developed. This plate has improved exposure latitude and is also very impressive in terms of print durability (2 million prints). The number reached 133l. Plates treated with water, due to its low cost, rapid processing, and good printability, will become the mainstream of flexographic plates in the future.
In fact, for those who think that flexographic prints are difficult to achieve, they will quickly change their opinion as long as they look at the packaging that won this year at EFTA.
