ID card Processing: How It All Works

The Direct-to-Card printing technology further uses two significant methods: dye-sublimation and resin thermal transfer. Dye-sublimation is the process in which the dye is transferred to a material using heat. Dye-sublimation, today, is better off called dye diffusion to kill the concept of turning solid to gas without getting onto the liquid state (which is the scientific idea of the word sublimation) which is not really observed in the entire process. The images obtained after the process are print-smooth, continuous-tone images on plastic cards, which are photographic in looks. This image quality was derived from the color panels which are grouped in a repeating series of colors.

These colors are called YMC or Yellow, Magenta, and Cyan. The print heads which actually contains thermal elements heats the dyes on the ribbon. The dyes then evaporate and disperse into the card. The color panels have their own ways. Through the combination of YMC and through the use of different degrees of heat, the colors are transferred and the printer may produce varying colors. The resin thermal method on the other hand uses only one ribbon. This single-ribbon is used to print black text on plastic cards. It may also print crisp bar codes. This differs only with the dye-sublimation process because of its use of transferred solid dots of color instead of making combination of colors through heat pressure.

Retransfer printing on the other hand is relocating an image to a retransfer film before it is placed on a card. The process first uses a clear layer of film where the image is reverse directly printed. After which, using heat and pressure the print heads grow to a certain temperature then the image films are then bonded. Other than printing an image to a certain card, card printers also offer other applications such as encoding information into the card. This is an advantageous application as it provides security and safety of the card.

Encoding information directly to the card can be less of a hassle from minor and major errors and counterfeiting of card use due to erroneously and manually decoded information. Card printing process works complicatedly, but it provides efficiency, simplicity, and accuracy. Efficiency in such a way that printing do not cost a lot of days before it is released unlike really traditional ways of ID printing. The easy management of ID makes it a very simple process to those who are well-learned about this. It also provides accuracy when it comes to reading and recording barcode and other information with just one swipe.
