The old saying “change is good†also applies to color proofs, and its changes are obvious to all. Following the development trend of the entire industry, color proofing quickly shifted from analog to digital, and eventually digital proofing occurred. Now people already know how to use it, where to use it and benefit from it. But what is strange is that analog proofing has not stopped the pace of development, and is no longer a subtle change.
Is it a simulation of the previous system?
Simulation proofing is actually a proofing method for film. When proofing is required, the film has to be transferred from one place to another. The user gets a proof of the film. Since the data is locked in the film and will not change, using film as a medium for transferring data is a good method. However, with the continuous standardization of the file format, this proofing method is also changing.
The main direction of change is to transmit data through the network, but in the process of transmission, it will encounter many problems, such as fonts, overprints, and software version compatibility. At present, the commonly accepted file formats in the industry are TIFF/IT and PDF formats. Using such a standard file format to digitally transfer files can overcome many problems, and at the same time can basically guarantee that when copying in the same manner, Stability, predictability, and credibility.
Digital Trends On the one hand, the development of digital proofing is very fast. People have begun to adopt and trust this technology and have a deeper understanding of it. This is the result of spending some time. They believe that the use of digital proofing technology is very handy, and can benefit from it, and with the deepening of proficiency and understanding, they know how to solve problems that may be encountered.
On the other hand, analog proofing has been around for about 22 years, and users have reached a very proficient level. In fact, anyone in the printing field may have obtained mock-up proofs, and can roughly describe the type of use and related specifications and parameters (eg, whether to print using SWOP - web offset publication specification parameters or to use Commercial printing methods; what type of dot gain value should be used).
However, digital proofing broke this situation. Any proofs are different from the past, they appear in a variety of different formats (with or without dots), and they are different (inkjet, thermal sublimation, thermal development and thermal transfer). For each person, to understand the continuous tone sample without a network, and compare it with the proofs with a network point to understand its formation process and the principle requires a long learning process.
After recognition of its quality, people feel that they can choose this kind of continuous proofing method and realize that when considering the turnaround time of printed jobs, the quality level of the final printed sheets, and other issues (such as moiré), the choice is still Many of them are not limited to analog proofing.
But the change is not easily accepted by some people, so some manufacturers use various methods to help people who do not want to turn to digital proofing to change their minds. Fuji Corporation has developed two systems and has already invested in the market:
PictroProof - This is a dye-based double-page continuous proofing machine that is positioned inside the proofing and does some proofing without a halftone dot; FinalProof - a four-page high quality proofing proofer, is actually a Fuji The exact copying of ColorArt, the proofing machine, can print halftone dots, pigments and use the same screening method on the actual printing materials used.
What else needs to be done for an all-digital process?
When all the digital devices are there, but there are quite a few people who have not changed their minds and adopted them, what should be done in the face of such facts? Now the company can completely operate without film, from digital information to digital proofing, modify and re-do a digital proof, after confirmation, go to computer direct plate (CTP) equipment or direct imaging press, and then print copy, and simulation The method is as accurate.
In the past, there was a dispute between those who did a full digital process and those who did a simulation process. The latter believed that a complete digital process could not be achieved. In the process of production, they will encounter troubles and there will always be unexpected events, but this has become a thing of the past. Now they have done enough work on the adopted file format, industry standardization and improving the quality of CTP and digital proofs, so that a complete digital process can be used at every stage of the process.
