Do you accept the soft proofing of the screen

digital proofing is different from these hard proofing methods. There is no specific sample, and the customer or operator only obtains the proofing effect and information through the computer screen. Since the mid-1990s, the open color management technology based on computer technology developed and promoted by ICC has been recognized and vigorously promoted by software and hardware developers and related industries. Screen soft proofing technology and its application have made a leap forward development. In the past two years, there have been quite a lot of screen soft proofing products on display at relevant exhibitions. There are both local stand-alone proofing products and remote network proofing products. The proofing accuracy of high-end products has reached the requirements of Chang 1, gb/t 5464 (2) 010 "test method for incombustibility of building materials", is01182:2002 "test of reaction of building materials to fire - incombustibility test", and is applicable to the printing contract proofing requirements of the class a inspection code for the combustion performance classification of building materials. It has passed the swop certification, and some products have even been extended to the sample viewing platform in the printing workshop. Through the screen soft proofing system, remote customers can view samples, sign and pay for printing in any place that can be connected to the Internet. However, it is precisely because soft proofing is a computer-based and display media proofing technology that customers or operators have not received specific samples, so the biggest feature of soft proofing is that it can be seen and not touched. That is, based on this feature, soft proofing has not been recognized in the field of printing proofing, and insiders have never recognized the status of soft proofing

now, a very practical problem comes out. Is the effect of screen soft proofing authentic? Can it exist in the printing field as a truly independent proofing method? The answer is yes. Why? The following four aspects can fully explain why screen soft proofing can and should become an independent proofing method

people have long been used to using screen soft proofing

when everyone is skeptical of soft proofing and questions its ability, they have unconsciously used soft proofing, and they can't do without this kind of proofing. Why do you say that? Pay close attention to the things around you. When designers design, they use the computer screen to predict the effect of future prints? When you do text input and image processing, don't you also design prints based on the screen? When you make typesetting, don't you just adjust and correct the printed matter you are going to produce on the screen? In fact, all this can be called soft proofing on the screen, but the color requirements have not been improved to match the printing. However, the industry cannot deny the possibility of soft proofing. Since soft proofing has been deeply rooted in content proofing, as long as there is technical support, the development of soft proofing in simulating printing color is also possible

the hardware technology is mature

to carry out screen soft proofing, the first and most important is of course the display, and the most difficult problem that needs to be overcome all the time is the display. Due to the unstable color function of the display, it is difficult to guarantee the effect of screen soft proofing. But today, the performance of the display has been greatly improved

1. Greatly expand the original color gamut

the color gamut of the display is an important indicator of the display ability of the display. In order to realize the soft proofing of the screen, the most basic requirement of the display color gamut is to fully cover the printing color gamut. In fact, some monitors specially designed for screen soft proofing have done this

2. Stable color rendering performance

for screen soft proofing, the biggest feature is that it can be seen, not touched, and there is no physical sample. It is difficult for people to accept screen soft proofing as an independent proofing method, mainly because the display effect of the display is unstable, and it will change at any time, so there is no guarantee for customers or enterprises. If there is a problem with printed products, It is not convincing to either side. It can be seen that stability is the key to changing the fate of screen soft proofing. Nowadays, in terms of stability, in addition to the stability that has been greatly improved by the display manufacturers, the increasingly perfect screen correction program also provides a good guarantee for the stability of the display. As long as it is used properly, the display can be kept in a standard state

in January 2003, the remote director 2.0 calibration system developed by integrated color solutions (ICS) became the first display calibration system certified by swop. This means that through remote director 2.0, screen soft proofing can be carried out without printing proofing, which saves a lot of time and expenses for printing professionals. This calibration system uses Apple cinema display or apple cinema HD display and powermac G5 computer running Mac OS X. This means that at that time, apple LCD has been able to meet the requirements and meet the brightness and color range required by ICS screen proofing. Following the pace of apple, as a major manufacturer of monitors, Yizhuo is also striving for the market of soft proofing. The company has several monitors that meet the requirements of swop soft proofing certification. It is necessary to appropriately increase the breakpoint ratio value; The sample has not broken yet. In addition, Sony's SDM p232w/b display is also one of the swop Remote Proofing displays recommended by ICs

it can be seen that the technology of display, as one of the hardware of screen soft proofing, has matured, which has laid a good foundation for the development of screen soft proofing

in addition to the display, the measuring equipment is also another important hardware for screen software proofing. In addition to the measuring equipment used to make printed ICC documents, the key equipment used in the screen soft proofing system is the screen calibrator

the monacooptix display calibration system provided by aseli adopts the most advanced colorimeter and is equipped with powerful and easy-to-operate software to provide excellent configuration solutions for LCD and CRT displays. Gelinda (now merged with Ashley) has also developed spectrophotometer software that can be used in displays

the high-precision display correction equipment provides strong technical support for the efficient screen soft proofing system

software technology diversification

similar to the overall development of the IT industry, in the field of screen soft proofing, the development speed of software is much faster than that of hardware. In addition to the rapid update of technology, the selection of screen soft proofing control software is still diverse. For example, Kodak launched the matchprint virtual proofing solution, which can provide accurate RGB monitoring and observation of CMYK color, and can reliably predict the final printing color; The remote director 2.0 calibration system developed by ICS company directly cooperates with Ashley eye one PRO system. Software and hardware promote and match each other, and a stable and effective screen soft proofing system is realized. In fact, it can be seen that the Chinese market pays great attention to the circular economy and can become a relatively mature proofing system. As long as it is used effectively, the screen soft proofing can be applied to production as an independent proofing method

the evaluation of soft proofing on the screen is divided into subjective evaluation and objective evaluation. Objective evaluation is easy to understand, that is, through the instrument to detect under certain observation conditions, and then analyze the data. This is similar to the general color management method. However, subjective evaluation is more difficult. The factors related to subjective evaluation include people, light sources and luminous objects (displays). Among these factors, people are the most subjective, and the factors vary greatly, so they are generally standardized for light sources and displays. At present, there have been standardized provisions for light sources and displays

1. The environmental conditions for soft proofing of screens are included in the international standard for the standardization of viewing light environment, which was formulated in the 1990s. At the same time, China also referred to the European standard light source standard and the relevant American standards, and formulated an industry standard called color evaluation observation conditions, namely cy/t3 industry standard, which is an industry standard transformed from international standards. This standard involves four requirements: color temperature, color rendering coefficient, illumination and observation conditions. By limiting the influencing factors of visual observation, the effect of observation is as consistent as possible

2. Display standardization

in order to standardize and standardize displays in production, the TC130 Committee of the international organization for standardization has formulated the iso12646 international standard. This standard has made detailed requirements for the technology of the display, including the provisions of the following parameters: resolution, size, refresh speed, uniformity, geometric accuracy, focusing, environmental lighting, chromaticity and brightness of white and black dots, and unified adjustment

the perfect standards provide a good guarantee for customers and enterprises to use screen soft proofing, and to a great extent, remove the psychological barriers brought by screen soft proofing

today, the screen soft proofing is technically mature and stable. The biggest advantage of screen soft proofing is its fast speed and low cost, which well meets the requirements of modern enterprises for high efficiency. Although many people in the industry have not been able to accept the scheme of screen soft proofing, this technology has gradually penetrated into some cutting-edge enterprises. In foreign countries, the most successful pioneers are time magazine and some of its publishers, which have successfully used remote soft proofing. Now, all customers of time magazine need to send soft proofing documents to time magazine. In China, Beijing Hualian Printing Co., Ltd., Beijing shengcaihong plate making and Printing Technology Co., Ltd. and Beijing Ruili magazine jointly conducted a screen soft proofing test. With the leadership of these leading enterprises and with advanced technical support, it is believed that in the near future, screen soft proofing will exist as an independent proofing method in many enterprises
