How far is "long-distance proofing"?

In a modern society, the work efficiency is getting higher and higher, and the rhythm is getting faster and faster. Accelerating the speed of color proofing and shortening proofing time have become urgent requirements of the printing industry. It's true how proofs are printed and modified. It takes time, but the delivery process can always be shortened. This leads to a new concept of “remote proofing”: users connect through the base T-1 or other high-speed network, and the printing and proofreading of the prints can be performed on the network, which saves delivery time and speeds up the proofing process. Created an excellent working model. However, how did this innovative and problem-simplified method not lead to a crowded scene and printers scrambling for a lively scene? Quality is a problem. Real life can't be as simple as talking. Although the main fortress hindering remote proofing has been conquered, the only real realization of a wide range of applications is the adoption of an agreed-upon quality standard. This is not an easy task. If the proofing work wants to “do something according to the contract”, the system must have: * Reliable and stable file source: The file cannot be misplaced, distorted or missing pictures; * The color and content can be reproduced accurately; High, easy to operate; * Efficient and economical transmission network system. The requirements are not simple. This is a problem with the file format for stable and reliable original file functions. Although Adobe, Agfa, Enfocus, Lantana, Cero, Heidelberg, Sai Angel are all working hard, PDF still does not replace Postscript, Quark, Illustrator, Photoshop, TIFF, etc., becoming the mainstream format for file transfer. Although it is flawed, PDF should satisfy the requirements for stable and reliable transmission of original files. AP Adsend uses it to send 75,000 advertisements a week. Remote proofing should also have the appropriate tools. PDFs can perform software proofreading, GroupLogic's ImageExpo can modify and discuss in real time, and RealTime Image can perform non-vector image corrections as well as Render View. Software applications are on the one hand, but the proofreading of most four-color prints also requires related equipment. Epson introduced the 3000 and -5000 series piezoelectric inkjet systems, followed by Canon, Hewlett-Packard, Minolta and so on. The price of their machines is lower than that of traditional proofers, and the effect is not bad. However, the use process must be very careful. Minolta and Imation jointly produced a full set of Color Laser Systems for proofing, but they used toner proofing. Questions about color management. Although some people suspect that this technology is procrastinating and they have found many other simple and inexpensive tools, the accuracy of those systems varies from person to person and is not suitable for creating or working environment. Although printing companies and prepress design companies are responsible for specifying relevant document formats before proofreading, the performance of these formats is often unstable and needs constant adjustment. Finally, mention the problem of transmission again. Big cities can rent T-1 transmission lines for about 700 yuan per month, which is lower than the courier fee. For smaller or no T-1 transmission lines, DSL lines can be used. Of course, such as through other special intranet or service providers DAX, DGNOnlin, Vio or WAM! Value-added services such as NET are also very good. We are looking forward to long-term proofing for a long time, but it is always because of this or that reason that we cannot come close to us. Like other new technologies that have just started, we are also watching its implementation. But now, it is not time for us to be nervous.
