The paper is made of many layers of plastic, laminated together. The center is usually made of a plastic resin known as polyvinyl chloride acetate (PVCA). This resin is mixed with other materials such as dyes and plasticizers to give the look and feel appropriate.
A number of ink or paint in various colors, used for printing credit cards. These inks and dyes are especially made for use on plastic. Special magnetic ink is also available to print the magneticStripe (magnetic stripe) on the back of the card. The ink is made by diffusion of particles of metal oxide resources. card issuers like Visa, which have their own holograms, special order more print jobs that are involved for cards, like VISA, with featured holograms.
The production of paper is required to perform the following steps:
1st plastic compounding and molding: The plastic sheet melts my heart PVCA with other materials.This mixture melted in appropriate equipment and molding plate thickness is adjusted by passing it through rollers. This sheet is then allowed to cool.
2nd Printing: Each sheet of paper printed with text and images. Syskermwerk and magnetic ink are the processes used. Magnetic tape can also be created by heating pad. magnetic heads are used to encode and decode the iron particles in the strip, so that relevant information can bestored in them. But the magnetic particles can be good if they are on the surface of paper, so this step is carried out after rolling.
3rd Lamination: lamination protects the card base and its strength increased. Lamination occurs on both sides of the card.
4th Cut and Embossing: rolling, after each sheet cut into a set of cards. Each page has a yield of about 63 cards. The plate is first cut into seven sections and longitudinalEach of the seven sections is cut into nine cards. Each card has a separate sheet and will be embossed with account numbers and other information. The cards are now ready for shipment to cardholders! Each card must be of excellent quality. Customers can not be given, will raise short or damaged, after a certain period. important aspects of quality in the composition of plastic and color matching. The American National Standards InstituteA standard for plastic raw materials (ANSI x4.16-1973). The ingredients must be properly weighed, mixed and blended according to the correct temperature and other conditions of production. Similarly, the process under control, casting defects, which may cause the cards to crack or fracture prevention. The final quality control is to ensure the correct numbers are printed on paper from the process of relief.
The many development technologies in this field will helpgenerate credit card with better quality and make them more cost effective in terms of production. New generations of credit cards can carry integrated computer chips, a lot of useful information, the paper more useful and secure.
