Experts talk about digital proofing

When it comes to printing proofing, proofing in the traditional sense is to proofread proofs through a proofer. Because the proofer can be regarded as a small, preliminary printer, its expensive price and large size limit the popularity of the proofer application. Generally only professional printers or large design companies have it. However, with the increasingly fierce competition in proofing and printing market, out of consideration for product cost and profit, “noble” proofing machines can no longer meet the needs of competition, and the emergence of digital proofing has become a printing factory and design company to adapt to market competition. And guarantee the best choice for profit. Compared with traditional proofing, the biggest advantage of digital proofing lies in its outstanding cost-effectiveness, speed, and direct output. With the rapid development in recent years, digital proofing has improved not only in proofing quality but also in proofing speed. Has a very broad space for development.

Digital Proofing "Eight Colors" New Era
When it comes to digital proofing, we must mention digital proofing equipment providers. The huge market demand has brought more participants. However, due to the relatively high technical threshold of the device, and digital proofing is the opportunity for the last color correction from the designer's computer screen to the large-volume print, it is the proof standard that the customer confirms, and it is the absolute standard of the final output of the printing factory. Proofing is so important in the printing process, so the proofing process has attracted the attention of both the printer and the user. At present, the active manufacturers in the market are limited to several large companies such as Epson, Hewlett-Packard, and Canon. Among these famous manufacturers, large format printers represented by Epson STYLUS PRO 7600/9600/10600 are widely used in the field of digital proofing, and have been widely praised by customers and their users. This year, Epson also introduced the Epson EPSON STYLUS PRO 4800 large-format printer and the "Century Iridescent K3" pigment ink according to the new changes in the digital proofing market. The new eight-color color system has completely updated the original seven-color system and applied a new one. The resin layer, and the addition of pale black ink, these innovations will make the color proofing effect more accurate, and make the color fast and stable! Fully meet the most critical requirements for digital proofing. At the beginning of this new product and the introduction of K3 ink, it has received extensive attention from the market. Many users believe that EPSON STYLUS PRO 4800 and Century Iris K3 pigment ink have brought a new standard and development direction to the digital printing field.

China's earliest entry into the field of digital proofing in the printing industry, Beijing Huali Zhicheng Technology Co., Ltd., which is known as the digital proofing authority, said when talking about domestic digital proofing equipment, Epson large format printers in the color gamut performance, output accuracy, print speed The excellent performance of various aspects such as the printing cost, the early many puzzles solved, the digital proofing is gradually accepted by the printing industry, more and more printing factories, output centers have begun to use digital proofing. The recently launched EPSON STYLUS PRO 4800 is even more advanced than the previous EPSON STYLUS PRO 7600/9600 in ink innovation! In particular, the accuracy of proofing is more stable.
Mr. Sun Yunxiang, Chairman of Hangzhou Yingtian, also used the EPSON STYLUS PRO 4800 and talked about his experiences with Epson's large-format output devices. Especially in the actual production process, Epson's latest EPSON STYLUS PRO 4800 brings more benefits. More value, this product is equipped with the latest "eight-color" ink, more suitable for digital proofing needs fast color stability, color more realistic, in practical applications can better restore a lot of high-end digital printing proofing effect It is accurate. Keep the output color perfectly consistent on a cost-free basis!

Experts look at digital proofing
As Beijing's largest prepress printing company, Beijing Shengcai Printing & Printing Technology Co., Ltd., has developed into a diversified printing plate making company such as computer plate making, output proofing and remote proofing in the domestic digital proofing market. There are more feelings and opinions in the development of the application. When talking about the most critical requirements for digital proofing, Chief Engineer Shen Zhiwei said: “The stability of digital proofing is very high. Different operators print the same file at different time periods. As long as the ICC PRODFILE parameter settings are the same, it is within the visual range. The chromatic aberration of proofs is not felt, and its color tunability depends on the configured color management software, and the output quality depends on the hardware parameters of the printer, such as resolution, ink droplet size, etc. Based on the principle of being responsible to the customer, the proofing must be certain. To ensure the accuracy and stability of color, the color requirements are often adjusted through several times of color management to ensure accurate output before the final output; and stability is to ensure that the adjustment is performed at different times after many times of color management. The two points are very important when the output of the batch can achieve the same exact result."

When it comes to the actual application of the EPSON STYLUS PRO 4800 digital proofing, Shen Gong said that "the 4800 fully meets the needs of the general users, especially with the random drive and color management, the user can obtain accurate color by simple operation; if Professional or large-scale companies use professional color management software for output to achieve a more perfect output effect.Here to emphasize, EPSON STYLUS PRO 4800 equipped with 'Century Iris K3' pigment ink according to my test, its The color gamut is very wide, and the color saturation is very high. For example, the original yellow color of the century's rainbow ink can only reach the level of more than 90, while the K3 ink can reach 108! It fully meets the high requirements for color and color gamut of proofing! Secondly, gray balance is very important in proofing. In the proofing effect, black tends to be greenish and reddish. This color cast is not easy to adjust with software, but I found out after using EPSON STYLUS PRO 4800 and K3 ink output. Thanks to the new eight-color color system and the addition of pale black ink, the gray balance in the output is very good. Various black color depth performance is very accurate, color transition, the level of outstanding. It is because of these Epson technical innovation, we will be able to obtain accurate, stable output effect! "

Digital proofing problems and development
The current digital proofing market is in the process of rapid development. The manufacturers have not only accelerated the research and development of new equipment, but also increased the development of solutions. At the same time, in practical applications, experts are constantly using new equipment to improve the proofing process and quality. For the current status of digital proofing, many experts also talked about the current problems. For example, the degree of automation of the current proofing software is not high, and often requires many times of color management adjustment (such as the adjustment of various curves of the ICC). The stability of the software needs to be strengthened. If the software can use different devices, the media can be relatively It is better to automatically calibrate and generate various curves; in addition, the hardware also puts forward corresponding requirements to ensure the quality of ink and paper, and the resulting changes are minor, if original ink and paper can be used. Can solve this problem very well, achieve ideal result. Secondly, printing accuracy can be further improved on the basis of guaranteeing the printing speed, and the speed and accuracy can be well unified.

The hardware and software issues will be solved gradually with the cooperation of hardware providers, software developers and application experts. How can the problems in the digital proofing industry be solved? Shen Gong said: “Digital proofing will be more widely used and popularized through several years of development. This will also highlight some problems. For example, many early- and mid-sized companies used digital proofing because they had strong technology and funds. Power support, but now many digital proofing SMEs do not have adequate support for equipment installation, maintenance, and adjustment, which in a sense has affected the development of this industry. If manufacturers, large companies can work together to provide more support, then the digital proofing market will Will be faster and more mature in China!"
