Screen soft proofing: what you see is what you get (I)

in printing, when people get used to the screen, they never stop pursuing "what you see is what you get". With the continuous improvement of software and hardware technology, we are getting closer and closer to "what we see is what we get", so the screen soft proofing has been paid more and more attention by the printing industry. For many printing enterprises in China, can screen soft proofing be recognized and developed rapidly? Where is the screen soft proofing path? To this end, the magazine interviewed industry experts and front-line practitioners to jointly discuss the technology related to screen soft proofing. We would like to express our deep appreciation to the industry experts yinyoufang and Mr. xietiesheng, as well as Mr. liuwenbin and Mr. chenyaxiong of China business for their help

(I) what is screen soft proofing

1. what is screen soft proofing

generally speaking, screen soft proofing is a proofing method that simulates and displays the printing output effect on the screen. It enables the printed live parts to preview on the display at any time before printing, that is, the display replaces the original paper and other media. In fact, this method is not very novel. Now many people often preview page content by exchanging PDF files, which can also be understood as an original way of screen soft proofing

since ICs remote proof 2.0 obtained swop certification as the first screen based proofing system, soft proofing has become a valuable topic. Then Kodak poly light launched its screen soft proofing system, matchpr 10t v1rtual

swop certification confirms an incredible concept. Thanks to the industry-renowned swop certification, the screen soft proofing system has the credibility. People can use the swop certified soft proofing system to directly examine the printing effect on the screen without relying on the actual proofing to simulate the printing effect. Therefore, hard proofing samples can be discarded

2. use of screen soft proofing

screen soft proofing can be used for printing live parts from design and production to graphic preview in the printing process, and even as a contract digital signature between the printing factory and the customer, which is also a more widely used method at present

Remote Proofing is another application field of screen soft proofing. There are two main methods for Remote Proofing based on display: one is to transfer PDF files by mail, and the other is to directly transfer files to the customer's FTP site. Both methods are used to check the page content and layout by the customer, or simulate the hard copy sample by using the precise color management system

3。 Implementation of screen soft proofing

behind the screen soft proofing is the color management technology. To display the output printing effect on the screen, the key is the consistency between the screen display effect and the hard proofing. Therefore, with ICC Color Management Technology, the screen soft proofing can be realized to a certain extent. Of course, it also needs to be equipped with relevant hardware, such as display, screen calibration instrument, standard light source, etc

there are many ways to realize screen soft proofing. Many graphic and image software now include the function of formulating ICC files, so it can also realize screen soft proofing to a certain extent, but it is not professional enough

nowadays, there are many professional software proofing systems in the market, including hardware and software to choose from, and the price is generally acceptable. The products provided by some manufacturers can even be used for contract sample signing. In China, in addition to professional software for screen soft proofing, many printing enterprises are now using Photoshop, InDesign and other common graphics and image software for screen soft proofing

(II) why do you perform screen soft proofing?

when it comes to screen soft proofing, you should mention hard proofing. Proofing has two main functions. One is to provide users with printing samples equivalent to the printing effect for customers to modify and sign samples. It is a way to convey customers' intentions in the production of a) the oil pipe is a chain connecting the oil pump and the jaw; Second, as a bridge between prepress and printing department, it checks the quality of prepress production and provides correct operation guidance for the printing machine. Therefore, proofing is an indispensable part in the printing process

both traditional mechanical proofing and emerging digital proofing require a certain amount of time, which may become a bottleneck in the printing process. Especially now, more and more people need to check and sign samples, such as front-end designers, printing customers, printing operators, and more often, these departments are located in different places. At this time, soft proofing is not only an ideal mode to reduce the weight of the car, but also essential. Otherwise, it will cost a lot of time and manpower in the process of transferring the samples. In this sense, the screen soft proofing can save a lot of costs

while saving time and cost, fast feedback is also a major advantage of soft proofing. Before adopting soft proofing, some businesses, especially the prepress production of high-end picture albums, often need to be repaired repeatedly. They need to test the non specific elongation Rp0.2 or specify the total elongation RT change. They need to negotiate and confirm with customers repeatedly. If the hard copy method is adopted, it needs to be output repeatedly, which is not only cumbersome, but also a waste of many digital proofing, Soft proofing on the screen makes it possible for many people to view and annotate proofs at different places at the same time. It can modify documents repeatedly in real time and interactively. It can also conduct remote proofing to effectively control publishing requirements. For live parts with urgent requirements, such as magazines, soft proofing and proofing can be carried out inside the publishing house to shorten the confirmation time
