Random talk on CD-ROM pad printing technology in silk printing and offset printing (Part 1)
the most commonly used CD-ROM printing methods are silk printing and offset printing, and pad printing is a relatively new situation. As a special printing process, pad printing technology has always been closely related to printing in its field of expertise. Where printing can be applied, pad printing often pays attention to it as a friend
optical disc is the latest way of information recording in modern society. It can not only record the graphic information originally recorded by strengthening the management of hydraulic oil books, but also record multimedia information such as sound and video. However, the information recorded in the CD-ROM is not as visible as that in books. It can only be read and written with the help of lasers, that is, it records some "invisible things", which must be restored to the "original state" by modern technology in order to be recognized by people. If you give such a thing to an ancient erudite bachelor to study, it can only see a shiny disc different from laser sintering. This analogy also proves the importance of printing. Human history has been creating all kinds of black boxes, and printing can make us associate with its mystery. When we print this disc with a brief introduction, the bachelor will understand some of the contents recorded in the disc. Of course, curiosity will force him to smash the CD to search for the contents
when it comes to disc printing, pad printing technology is definitely not just for fun. In fact, the wonderful performance of pad printing technology on CDs has been recognized by more and more people in the industry. It is undoubtedly the most successful to use offset printing to print optical discs. It has the highest resolution and the fastest printing speed. But its speed is too fast. If the number of discs is not very large, offset printing is indeed not an ideal choice. The cost of offset press is not affordable. Therefore, printing often replaces offset printing. There are many advantages of India, but one disadvantage is fatal. When the plate is pressed down on the disc and the scraper is used for scraping, the pressure fluctuates from one end to the other end. Because the discs are thin sheets with a thickness of less than 1.5mm, they are very light and will always be slightly rubbed, which often affects the printing quality. Many CD printing centers can start business after purchasing a few printers. Printing CD is a good thing, but it is not easy to ensure the printing quality. Because the CD-ROM needs to be transferred from one machine to another during multi-color overprint, the CD-ROM itself has no circumferential positioning mark, so it is difficult to achieve accurate overprint
advantages of CD pad printing technology
CD pad printing is a must for strategists, and it is natural for pad printing experts to pay attention to this market. The pressure of pad printing comes from the soft and elastic pad printing rubber head. It is pressed vertically from the top of the disc, and the position of the disc will not be affected in the printing process. Since the center of the disc is a central hole with a diameter of 15mm, the problem of blank area in the center of the rubber head can be eliminated. Multicolor pad printing machine is much simpler than multicolor printing machine. Of course, it is much more accurate for discs to receive multiple printing overprint in the same position
pad printing has always had advantages beyond printing, one of which is that it is very good at small area product printing. Although the discs are mainly large discs with a diameter of 120mm, the market share of 80mm small discs is becoming larger and larger. 1. Local discs and business card discs that regularly check whether there is oil leakage at the host and oil source emerge as the times require, which puts forward new topics for the adaptability of the printing process. The open workbench mechanism of the pad printing process makes it very convenient to place all kinds of fixtures, and it is also very simple to make special glue heads, especially the replacement of the pad printing plate is faster. The rapid gain of pad printing in favor of CD printing is by no means groundless
do you need color management
although CD-ROM carries greater value, its requirements for color are far less strict than those of paper publications. The main reason is that the pad printing machine manufacturing enterprises lack understanding of the cutting-edge technology of printing - color management. No enterprise can use the color management technology of other printing processes as the way of pad printing color control, so pad printing has been staying in the color quality space with large deviation. What are the differences between domestic film making experimental machines and imported experimental machines: there is a lack of effective color management means in the whole process of production, and its biggest risk lies in the control problem related to the superposition of optical disc pad printing points. Many enterprises are not complained about the problem of equipment, mainly focusing on the difficulty of color to meet the requirements of customer samples stably. Due to the lack of professional technicians to put forward effective improvement methods for color management, color management has always been a problem that manufacturers avoid. They would rather accept the inherent gap of pad printing than frankly point out the solution. Today, when the mainstream printing industry proposes to unconditionally push the quality requirements of customers to the limit, the key reason why pad printing is difficult to compete with them is that the color management of pad printing has not been paid attention to, and has not even been mentioned by most manufacturers
in any case, pad printing enterprises must begin to pay attention to color management, which is the only way for pad printing CD printing to become a favorite. Maybe we can't be as strict as offset printing, but at least we can establish this framework from today, and then gradually improve it. It is necessary for us to realize the digitization of the basic parameters of the film production process. We should start to use densitometers. We should understand the color characteristics of our computers, scanners, printers and laser imagesetters. Only in this way, pad printing technology can move forward step by step
