On the application of digital printing technology

Talking about the application of digital printing technology in the production of certificates and cards

card type certificates began in 1958. First, Americans applied them to driving licenses, which required high operating experience. Then, the emergence of identity cards, medical cards and credit cards made the card technology develop rapidly and the application scope expand greatly, It is characterized by the smart combination of card type electronic certificates and computer certificate making and identification technology brought by the national "made in China 2025" strategic exhibition of microelectronics technology development in Nanjing. Therefore, modern certificate making technology is card making technology

compared with European and American countries, the application field of card in China is far from wide enough and the depth of application is far less than that in developed countries, but the development speed of the application field and depth of card in China is gratifying. In 1993, with the official launch of the "gold card project" focusing on the application of electronic money in China, this intelligent and portable card was rapidly popularized and developed in China, opening up a broad market for China's electronic information industry. Abbott machinery (Shanghai) Co., Ltd. will introduce in detail how Abbott's injection molding machine can help the medical industry develop the market

card type

ordinary ID card - a kind of card that can be used as identity recognition, with market-oriented operation as the core card, and can carry the user's photo on it. ID cards are widely used in identification cards of students and employees, driver's licenses, various VIP cards, membership cards, etc

barcode card - uses international standard black-and-white stripes to store a large amount of information. It was first used in packaging identification, books and periodicals, mail and other aspects. It can be read out quickly and closely. Recently, a two-dimensional barcode has appeared, which can store cardholder photos. The information content is greatly improved, which is convenient for encryption and anti-counterfeiting, but it cannot be rewritten

magnetic (strip) card - a magnetic (strip) card is a card made by pasting a magnetic tape and signature strip with the function of storing information on a specific position on one side of the card type certificate, identifying the hologram, and printing the convex code. The magnetic strip has the function of storing information, while the signature strip, hologram, and corresponding number have the function of identity recognition

contact IC card - contact IC card is abbreviated as IC card. IC chip is embedded (or injected) on the card carrier, which has the function of storage or microprocessor. With large information capacity, it can store photos, fingerprints and other human physiological data, and has good security performance. It can run independently without relying on the database. The memory can be divided into multiple application areas to realize multiple uses of one card. Due to the above advantages, contact IC cards are widely used, but recently they have also been strongly impacted by non-contact IC cards

contactless IC card - Contactless IC card is referred to as inductive card for short. It inherits the strengths of contact IC card and improves the reading and writing mode of card. It is adjusted from electric signal contact reading and writing to wireless inductive reading and writing. In this way, contactless IC card shows great advantages for certificates that need to be used frequently or when working outdoors. Of course, due to the relatively complex manufacturing process of non-contact IC cards, and the need for special safe read-write modules for reading and writing machines, the price is higher than that of contact IC cards

rfid card - it is similar to a contactless card, but it is read-only and contains an RFID antenna embedded in it. Its advantage is that the RFID different frequency radar transceiver can be read out by the reader anywhere, including in the magnetic field, the antenna is buried in many objects (including cards), and the radio waves can pass through non-metallic objects and be read, which can prevent the data from being worn out in daily use and damaged under the influence of the environment. Theoretically, the readable distance is greater than 10ft

each of the above cards has its own characteristics. There are great differences in other aspects, such as business card printing process, processing technology, etc., but because PVC materials are generally used, they have the same properties in printing. Several traditional printing processes such as offset printing, gravure printing, embossing printing, silk screen printing, etc. can be used for the printing of cards, which requires the establishment of a production line through plate making and color printing machines. In the case of mass production, the purpose of reducing costs and improving economic benefits is achieved through economies of scale. However, for small batch and personalized prints, this method inevitably has the problems of high cost and long cycle, which is difficult to meet the requirements of customers, especially for some cards that require attaching photos and images to the cards to help identify, such as students' and employees' identification cards, access cards in special regions, admission cards, etc., this method cannot meet the requirements

the traditional production method relies on multiple steps such as printing/cutting/pasting/gelatinizing. First take a recent photo of yourself, and then cut and decorate it to adapt to business card printing; Then print the information of the person on another card material: then combine the photo and the card to make a card. This kind of card is easy to forge and tamper, and the production process is labor-consuming and time-consuming, which brings great inconvenience to people. In contrast, there is only one step in the digital printing process of the card, that is, to print the explanatory text, patterns and photos directly on the card through the computer system. These cards are usually the same size as credit cards and are made of PVC (or PVC). These cards can be printed on one side or both sides, either monochrome or color. The digital printing methods of cards include heat transfer printing and laser inkjet printing
