Throughout the development history of proofing, we can see that high-quality, low-cost, efficient and convenient proofing/proofing system has always been our goal, and the comprehensive proofing/proofing system has gradually become the mainstream of the industry. We can also see that in addition to pursuing the quality and efficiency of proofing, the quality and efficiency of the proofing process have also been greatly improved. The emergence of paperless proofing and remote proofing provide two solutions, which largely satisfy users' demands for high quality, low cost, and high efficiency and convenience.
Paperless proofing
The paperless concept of proofing is relative to the traditional paper media proofing concept. In general, paperless proofing refers to the use of high-quality computer monitors to reproduce proofs, and the process of proofing, also known as screen proofing, soft proofing, or virtual proofing. There are two requirements here: First, the monitor must meet the color standard of the printer. At present, display manufacturers such as EIZO, Sony, and Apple have been able to provide high-accuracy displays that meet the printing standards; second, the display of the display must meet the quality control requirements. The standard, using the ICC profile, we have been able to easily solve this problem. Compared with traditional paper media proofing, the characteristics of paperless proofing can be summarized as follows:
1. High efficiency. Due to the use of computer-controlled high-precision display output proofs, we can achieve proofing operations in an instant. Its convenience and productivity have been greatly improved.
2. The skill requirement of the operator is very low. Compared to paper media proofing operators, paperless proofing operators only need basic computer operation capabilities.
3. Health "zero" costs. Paperless proofing exists in the form of electronic documents. It does not require consumables such as paper ink. Output proofs do not require human and material transport and do not require a storage room. In addition to power consumption and equipment depreciation, the production of paperless proofs is almost negligible.
However, due to the customary reliance on traditional paper media proofing, users are highly skeptical about using the display to complete the proofing process. To sum up, there are several problems: the display is a luminous body, and the traditional proofs are reflectors; whether the monitor can truly reproduce the printed colors after correction; the display has individual differences.
At present, paperless proofing is mostly used for simple layout proofing and text proofing. Fortunately, a small number of forward-thinking companies have begun to explore this technology and have entered the trial phase.
Remote digital proofing
Remote digital proofing is also not a concept. It is relative to traditional stand-alone local proofing. Currently, it is generally based on paper media. In short, remote proofing solves the problem of off-site proofing for the same job. At present, there are many solutions that can be implemented. For example: Using the nested ICC profile PDF and high-speed network transmission and high-precision color inkjet output devices, we can efficiently achieve off-site proofing output of the same job. Strict color management system and accurate equipment calibration process can be very high proof quality. Remote proofing is an ideal offsite proofing output method. It has several obvious advantages:
1. High efficiency. Using high-speed network to transmit proofing documents and unified calibration output devices, remote proofing can achieve efficient proofing output from different places, saving off-site transportation.
2. High quality. Using modern color management technology and high-precision color output devices, the quality and consistency of off-site proofs are eliminated.
3. Low cost. Relative to local proofing off-site transportation, remote proofing saves on transportation costs.
At present, medium and high-end customers and medium and large-scale printing factories have already recognized this proofing method to a high degree. However, remote media proofing based on paper media has not achieved the same high efficiency remote proofing function. The cost will also increase exponentially because of the increase in the number of proofs. At the same time, the appearance of various printed sheets in different places also makes quality management difficult. Even contract disputes.
Paperless remote proofing
Simply put, paperless remote proofing is a type proofing program that uses paperless proofing technology to complete functions including remote proofing, proofing, and proofing. The paperless remote proofing system should have the following conditions:
1. Meet the quality standards of proofing. As a proofing system, the first is to be able to simulate the reproduction of the print result.
2. Paperless proofing. Through computer color management, using high-precision display output proofs to achieve paperless proofing process.
3. Remote proofing. Through the high-speed network transmission of the proofing file, the synchronous paperless proofing output of the same job can be achieved in different places.
4. Remote proofing / signing. Through high-speed network transmission and sharing of proofing files, the process of annotating, re-proofing, and signing the same job can be realized in different places.
In addition, since all proofs exist in electronic form, remote digital proofing without paper should also have cross-platform (Windows and MacOS) electronic proof storage management capabilities, client endorsements and sign-up authorization functions, and proof-of-concept uploads. , download and other functions.
Paperless remote proofing not only integrates the advantages of paperless proofing and remote digital proofing, but also effectively overcomes the deficiencies of both methods. The first is that the monitor meets the printing color standard: several displays of EIZO, SONY and Apple have obtained SWOP certification, which can correctly display the printing color; the screen correction tool factory provides advanced color correction equipment such as Glinda's I1, etc., controls the color difference between the screen and the printing standard within the deltaE2 that can be distinguished by the human eye. Secondly, the use of a luminous body to output proofs is to some extent an improvement. The proofs are affected very little by the light source and are no longer affected by other conditions such as temperature and humidity. The individual differences in the display are inevitable. Just as there are differences in the individual proofing devices, the test data shows that the individual errors of the high-precision display can be smaller than the paper proof output devices.
Due to the use of the same proofing job for outputting, proofing, and proofing, paperless remote proofing can effectively overcome the problems caused by the diversity of differences. However, like traditional digital proofing, paperless remote proofing does not perform well when simulating special spot colors (such as metallic colors), and lacks the ability to simulate special processes for packaging and printing.
Recalling that digital proofing entered China several years ago, users are skeptical about using non-printing methods to simulate printing results. Today it is difficult for us to find a printing factory that does not accept digital proofing. By avoiding weaknesses, the comprehensive proofing system has become the mainstream. Technological progress has brought us benefits. Paperless remote proofing has also gone through a process from recognition to acceptance, but it has been much shorter. Due to the excellence in proof-making/annotation-reproofing-licensing and the features of high quality, convenience, and low energy consumption, paperless remote proofing has become an integral part of the integrated proofing system in the United States. As the printer of "Times Weekly", the famous American printing company BrownPrintingCompany has a deep impression: The biggest benefit of paperless remote proofing is that it is no longer necessary to place the same one in the branch printing factories all over the United States as in the past. There are several different proofs for the job, but the car must be printed according to the proofs they had never seen before. The degree of automation at the same time (mainly the proofing process) is greatly improved.
With advanced screen display technology and color management tools as the guarantee, paperless remote proofing will certainly add luster to the rapid development of China's printing industry.
