Thermal Transfer Technology (6)

Digital inkjet thermal sublimation transfer is the use of digital cameras or scanners and professional gallery images to data, through the computer for image processing and design, made of the required colorful, delicate images, and then through the use of dedicated thermal sublimation Ink-jet ink-jet printer prints the ink on a base paper in a computer-designed image, and then heats the image on the transfer paper through a roasting machine, a pan-baking machine or a rotograter. The image is transferred to porcelain in a few minutes. Plates, t-shirts and other souvenirs.

1. Sublimation transfer printing paper production

Sublimation transfer printing paper production process is similar to the digital color inkjet proofing system, that is, the computer will be thermal transfer of text, photos, etc. for processing and design, using a digital inkjet printer to print on the base paper, digital inkjet The printer is equipped with four independent ink cartridges, yellow, blue, black, and black, so that monochrome images can be printed on the base paper, and color images can also be produced. This inkjet printer saves the plate making process, reduces the production cost, and makes the thermal transfer process more simple.

2. Heat transfer patterns on souvenirs such as cups, plates, and plates

Using an electronically controlled baking cup machine, the pattern on the dye-sublimation transfer paper can be transferred to the cup in a matter of minutes. Using a baking cup machine to make a beautiful, full-color picture on the cup, the required consumption village is just a special transfer ink and a cup with a special coating, and the operation is convenient and quick.

The pattern on the dye-sublimation transfer paper can be transferred to the plate in minutes using an electronic digitally controlled baking pan. Equipped with a special transfer ink, the use of a baking machine can be baked on a special plate to produce a variety of patterns.

With an electronic digital control printer, the pattern on the dye-sublimation transfer paper can be transferred to porcelain plates and metal plates in a matter of minutes. Applicable to the production of medals, honor certificates, commemorative cards, portraits porcelain.

(C) Smart Card Dye Sublimation Infiltration Color Imaging Technology

Card printing has earlier printing methods such as plain printing, embossing, gravure printing and screen printing. With the rapid development of high-tech, card printing has developed into thermal transfer and sublimation transfer printing. Thermal transfer has been discussed in the foregoing, and now the main application of sublimation transfer printing in card printing is described.

There are two forms of color sublimation transfer card printing. One is the use of a ribbon. The ribbon is coated with four layers of yellow, white, blue and black. Each length is equal to the length of the card. Taking the PTSO00 smart card device sold by Beijing Leopard Technology Development Co., Ltd. as an example, the print speed is 28s/card, the print head resolution is 12dot/mm (300dpi), and the ribbon can print 250 cards. Card surface materials are PVC and PET.

There is also a color separation ribbon. The color printing process is printed by four ribbons of blue, yellow, yellow, and black respectively. That is, only one color ribbon is installed per color printing unit, thereby avoiding the traditional four color segments. The inherent disadvantages of ribbons have reduced the cost of consumables, enabled color customization, and extended the life of printheads. For example, the printing resolution of PT6000 smart card equipment sold by Beijing Panchi Technology Development Co., Ltd. is 300dpi, the maximum production speed is 650 cards/h (including data transmission time), the printable capacity of ribbons is 3300 to 10,000 cards, and the card material ABS , PC, PET, PVC and so on.
